Повний текст джерелаSARAF, Manish Kumar. Polymerization of Vinylidene Fluoride in Supercritical Carbon Dioxide: Molecular Weight Distribution (Under the direction of Drs. George W. Roberts and Joseph M. DeSimone)Conventional vinylidene fluoride polymerizations require the use of large amounts of water. Therefore, energy and cost-intensive drying and separation steps are required to isolate the polymer. Additionally, some conventional polymerizations use fluorosurfactants that belong to 3M?s ?Scotchgard? family of surfactants, which are being phased out due to environmental concerns. In this research, we investigate a "green" process for the continuous polymerization of vinylidene fluoride by free-radical precipitation polymerization in supercritical carbon dioxide (scCO2). Significant technological and environmental improvements can be achieved by this technology, such as: 1) elimination of waste streams generated by conventional suspension, and emulsion processes; and 2) achievement of major energy savings, as the polymer is isolated in a dry form with no water or solvent to evaporate. The experimental system used in this research consisted of a continuous stirred tank reactor (CSTR) for polymerization, and a polymer withdrawal system where polymer was collected, and continuously ejected to ambient conditions. The polymer was collected as a dry "free-flowing" powder, and was characterized by GPC (gel permeation chromatography), DSC (differential scanning calorimetry), and Fluorine-19 NMR (nuclear magnetic resonance spectroscopy). Experiments were carried out to study the effect of different parameters such as inlet monomer concentration ([M]in= 0.78 to 3.5 M), pressure (P=3050 to 4400 psig) , temperature (T=65 to 85 oC) , and average residence time (t = 12 to 50 mins.), on the polymerization rate and the average molecular weights. A homogeneous model based on classical free radical kinetics predicted the polymerization rate very well at the lower rates. However, this could not predict an inhibition in the rate that was observed at higher monomer concentrations. A bimodal molecular weight distribution was obtained at inlet monomer concentrations greater than around 1.9 M. The second (high molecular weight) mode was more prominent at higher monomer concentrations, higher residence times, and lower temperatures. Two hypothesis, poor mixing and long chain branching, were investigated to explain these broad and bimodal molecular weight distributions (MWDs). Agitation studies showed that poor mixing can account for the slower rate of polymerization at high monomer concentrations, but does not to bimodal MWDs. End group analysis using NMR showed that chain transfer occurs, probably to polymer. A homogeneous kinetic model was developed to investigate the effect of chain branching arising from chain transfer to polymer. This model showed that broad MWDs with large polydispersity indices (PDIs) are obtained at high monomer concentrations and at high residence times. These predictions matched very well with experimental data. However, the model predicted a unimodal MWD even at very high values of the rate constant for chain transfer to polymer.Batch polymerization studies were carried out to develop alternate low temperature initiators, which could reduce operating and equipment costs and potentially produce high molecular weight polymer with reasonable yields. A fluorinated initiator obtained from hexafluoropropynl oxide dimer produced PVDF with very high molecular weights (~90 K) at reasonable yields.

Повний текст джерелаMany ferroelectric devices benefit from the ability to deposit thin ferroelectric layers. Poly(vinylidene) fluoride (PVDF) is the prototypical ferroelectric polymer, but processing of thin film ferroelectric PVDF remains a challenge due to the formation of large voids in the film during traditional thin film processing. The research described in this dissertation starts by investigating the origin of these voids. The cause of these voids is found to be caused by vapor induced phase separation (VIPS). Guided by the thermodynamics of VIPS, a process is then designed to produce void-free ferroelectric PVDF thin films on polar and non-polar substrates. The films are shown to have a high remnant polarization (~6.5 C m–2). The later part of this dissertation is focused on understanding the temperature and structural phase dependent kinetics of polarization switching in PVDF films. A polarization switching model is developed with considerations of Avrami nucleation and growth, local electric fields, temperature and structural phase. The kinetics of polarization switching are shown to follow a universal behavior when correctly accounting for temperature and structural phase.

Повний текст джерелаThis thesis work deals with an understanding of the versatile roles of phosphonium ionic liquids (ILs) as nanostructuration and interfacial agents for the fluorinated polymer matrix, i.e.,poly(vinylidene fluoride-chlorotrifluoroethylene) (P(VDF-CTFE)). In this context, two phosphonium ILs with different functionalities in steric hindrance and extra dipolar groups are firstly incorporated in P(VDF-CTFE) matrix to prepare polymer films. The crystalline phase structure, dispersion morphology and crystallization behavior are finely characterized with the goal of providing a full and deep understanding of the versatile and tunable nanostructuration effect of phosphonium ILs. Subsequently, in order to elucidate the mechanism of interfacial influence of IL, a fluorinated phosphonium IL with a cation structure combining three phenyls and a short fluorinated chain is added on the surface of graphene oxide (GO) and reduced graphene oxide (rGO), making them as functional nanofillers to be incorporated into P(VDF-CTFE) matrix. Thus,P(VDF-CTFE)/graphene composite films with different filler contents are prepared in order to investigate the mechanism of interfacial interaction and its influence on the composite films, such as crystalline phase structure, crystallization behavior, chain segmental relaxation behavior, dispersion morphology and the final dielectric properties

Повний текст джерелаStructural safety and integrity continues to be an issue of utmost concern in our world today. Existing infrastructures in civil, commercial, and military applications are beginning to see issues associated with age and environmental conditions. In addition, new materials are being put to service that are not yet fully characterized and understood when it comes to long term behavior. In order to assess the structural health of both old and new materials, it is necessary to implement a technique for monitoring wear and tear. Current methods that are being used today typically depend on visual inspection techniques or handheld instruments. These methods are not always ideal for large structures as they become very tedious leading to a substantial amount of both time and money spent. More recently, composite materials have been introduced into applications that can benefit from high strength-to-weight ratio materials. However, the use of more complex materials (such as composites) leads to a high demand of structural health monitoring techniques, since the damage is often internal and not visible to the naked eye. The work performed in this thesis examines the methods that can be used for phase change activation and characterization of sprayable poly(vinylidene) fluoride (PVDF) thin films in order to exploit their piezoelectric characteristics for sensing applications. PVDF is widely accepted to exist in four phases: alpha, beta, gamma, and delta. Alpha phase PVDF is produced directly from the melt and exhibits no piezoelectric properties. The activation or transition from α phase to some combination of beta and/or gamma phase PVDF leads to a polarizable piezoelectric thin film to be used in sensing applications. The work herein presents the methods used to activate phase change in PVDF, such as mechanical stretching, annealing, and chemical composition, to be able to implement PVDF as an impact detection sensor. The results and analysis provided in this thesis will present the possibilities of spray-deposited PVDF thin films in both small-scale and large-scale sensing applications that can be applied to both simple and complex geometries.

Повний текст джерелаThis dissertation shows how the morphology and polymorphism of poly(vinylidene fluoride) (PVDF) membranes prepared by using vapor-induced phase separation (VIPS) and liquid-induced phase separation (LIPS) were tuned by varying the dissolution temperature at which PVDF was dissolved (Tdis) to form the casting solution. We observed a transition temperature denoted by critical dissolution temperature, Tcri, across which the morphology and polymorphism of membranes (obtained by VIPS) drastically changed. The phenomenon was considered as general, as a Tcri was observed for all the three solvents N-methyl-2-pyrrolidone (NMP), dimethylacetamide (DMAc), and N,N-dimethylformamide (DMF) and the non-solvents, water and a series of alcohols, used in the present study. No matter which Tdis we used, polymer crystallization occurred prior to the L-L demixing. With Tdis above Tcri, the prepared membranes were composed of nodules (mainly in beta crystalline form) and the size of polymer domains decreased as the Tdis decreased. Because the polymer chains could freely coarsen to a large domain during the phase separation, we called the system free coarsening. With Tdis below Tcri, membranes with lacy (bi-continuous) structure (mainly in alpha crystalline form) were obtained. Because the polymer solution gelled during the phase separation, we called the system hindered coarsening. It was proven that PVDF membrane morphology and crystalline polymorphs can be monitored by Tdis and the solvent-nonsolvent exchange rate. These results were discussed in terms of self-seeding effect and competition between the gelation, crystallisation and L-L demixing

Ferrocenyl ferrocenyl-substituted allenylidene complexes [(η5-C5H5)(L)2Ru=C=C=C (Ph)(Fc)][PF6] (L = PPh3, 1a; 1/2 dppe, 1b) was prepared by treatment of a methanol solution of (η5-C5H5)(L)2RuCl (L = PPh3, 1/2 dppe) with the propargylic alcohol 1-ferrocenyl-1-phenylprop-2-yn-1-ol in the presence of NH4PF6. Reaction of 1a-b with Grignard reagent RMgBr or MeLi in THF yielded the neutral acetylide complexes 2a-3d (η5-C5H5)(L)2Ru-C≡CCPh(Fc)R (Fc = (η5-C5H4)Fe(η5-C5H5), L = PPh3, R = CH2CH=CH2, 2a; R = CH2C≡CH, 2b; R = CH2C(CH3)=CH2, 2c; L = 1/2 dppe, R = CH2CH=CH2, 3a; R = CH2C≡CH, 3b; R = CH2C(CH3)=CH2, 3c; R = Me, 3d). Complexes 2a-3d undergo protonation reactions affording the corresponding vinylidene complexes 4a-5d [(η5-C5H5)(L)2Ru=C=CHCPh(Fc)R]+ (L = PPh3 ,R = CH2CH=CH2, 4a; R = CH2C≡CH, 4b; R = CH2C(CH3)=CH2, 4c; L = 1/2 dppe, R = CH2CH=CH2, 4a; R = CH2C≡CH, 4b; R = CH2C(CH3)=CH2, 4c; R = Me, 4d). The cationic complex 4a in methanol solution for 12h followed by subsequent addition of NaOMe to give the new neutral acetylide complex (η5-C5H5)(PPh3)2Ru-C≡C-CH2C (Ph)([Fc])CH=CH2 (6). This transformation was proposed that a metathesis process of the terminal vinyl group with the C=C of the vinylidene group as mechanism. The presence of a gem-ferrocenylphenylmethylene moiety at the vinylidene ligand with the appropriate terminal vinyl or alkynyl group along with the correct steric environment implements such a specific reactivity in the ruthenium vinylidene complexes. The bisvinylidene complex [Ru]=C=C(Ph)CH2CH=C=[Ru]2+ (8) ([Ru] = (η5-C5H5) (dppe)Ru) can be obtained from the reaction of {[Ru]=C=CPhCH2C≡CH}+ with [Ru]Cl in the presence of NH4PF6 and methanol. Deprotonation of the bisvinylidene complex 8 formed the alkylnyl vinylidene complex [Ru]=C=C(Ph)CH2C≡C-[Ru]+ (9), which was alkylated by primary alkyl halide to give the ruthenium bisvinylidene complex [Ru]=C=C(Ph)CH2C(CH2R)=C=[Ru]2+ (R = CN, 10a; R = COOMe, 10b; R = C≡CH, 10c). Deprotonation of 10a by NaOMe is followed by a cyclization process yielding the stable complex 11, containing a three-membered carbocyclic ring ligand, which is characterized by NMR spectroscopy. No deprotonation reactions of 10c was observed under various basic conditions. Deprotonation reaction of the cationic isocyanide complexes of molybdenum {[Mo]-C≡NCH2C6F5}Br ([Mo] = (η7-C7H7)(dppe)Mo), with NaOMe in the presence of acetone leads to the synthesis of oxazolinyl complexes 13. This reaction proceeds via an azirinyl intermediate detected by NMR spectra followed by insertion of a carbonyl group into the C-C single bond of the three-membered ring. Regiochemistry of the C-C bond formation is different from that in the photolytically induced insertion of carbonyl compound to organic azirine. Methyl substituted isocyanide complex 14 containing a stereogenic carbon center was obtained by treatment of iodomethane with oxazolinyl complex 13. Complex 14 are determined by X-ray diffraction studies.
