Full textThe aim of this study is the synthesis of controlled surface energy polyurethanes with hydrophilic or hydrophobie behaviour. Ta this objective, some reactive surface active agents with different natures and chemical s t ructures were introduced in the formulations. In accordance with the Fowkes's approach, the two cornponent s of the surface energy are determined from advancing and receeding liquid contact angles onto polyurethane surfaces. The observed hysteresis is attributed ta the environment change at the surface, and is related ta molecular motions and also to liquid absorption effects. In some cases , hysteresis can be attributed ta local surface deformation caused by capillary forces. The chemical nature of each polyurethane constituents (macrodiol, diisocyanate, cross-linking agent) was varied. Surface energy was found ta be dependent on bath the macrodiol nature and the presence of molecule substituents. The polyurethane surface modification was then carried out by introducing different amounts of surfactants with different chemical structures and mobilities. The role of glass transition temperature was also studied

Full textThe development of new chiral molecules is a major challenge since few decades. This PhD work focuses on the synthesis and the characterisation of a variety of molecules based on helicenes. Indeed, helicenes are chiral and show exceptional chiroptical properties. Therefore, combining these chiral entities with various motifs allow the modulation of their properties. In a first part of this manuscript, we were interested in the association of helicenes with tetrathiafulvalene (TTF), thus combining the redox properties of TTF with the chirality of helicenes. The second part concerns the preparation of luminescent helicenes based on benzothiadiazole and BODIPY for circularly polarised light luminescence (CPL). In a third part we investigated the self-assembly and the reactivity of helicenes on gold and copper surfaces. Finally, we have prepared single molecule junctions based on helicenes. In Conclusion, we developed different redox and photoactive helicenes with applications towards the self-assembly on surfaces and single molecular junctions

Full textThis thesis focuses on two topics ubiquitous in soft matter: first, mediated interactions between nano-to-micrometer sized objects, second, surface tension in out-of-equilibrium systems. The first part of this thesis is devoted to the properties of a system of particles whose interactions are mediated by a fluctuating background. We start with a nonequilibrium study and we show that the combination of mediated interactions and of the nonequilibrium drive leads to complex structures. Our predictions, beyond statistical mechanical methods, rest on extending the methods of nonlinear dynamics in pattern forming systems, to systems with a local conservation law. The second study of this part is dedicated to an equilibrium experimental system of colloidal particles embedded in lyotropic lamellar phases. Relying on a bottom-up approach, we implement the details of the interaction between each colloidal particle and each lamella to come up with an exact description of the effective force emerging between colloids. These analytical results are then used to discriminate between two types of interaction, both being possibly encountered in experiments. The second part of this thesis focuses on the notion of surface tension for interfaces involving active fluids. We will come up with a definition relating macroscopic forces to microscopic ones, either between particles or, when applicable, between particles and a confining medium. When the active fluid is in contact with a solid boundary, the solid-fluid surface tension is, in general, a more complex quantity than its equilibrium counterpart. By this we mean that its value may depend on the geometry or other details of the measuring device. We will also show that a carefully designed probe allows us to access an equation-of-state-abiding surface tension akin to its equilibrium counterpart. Liquid-vapor interfaces can also be encountered in assemblies of self-propelled particles when these undergo a motility-induced phase separation. We show also that the surface tension associated to a liquid-vapor interface possesses a mechanical definition that echoes the equilibrium one

Full textTextiles are widely used in medical devices which are implantable or not (wound dressing, vascular prosthesis etc…) and researches currently aim to bring them therapeutic properties (antibacterial, healing, regenerative). Among the most efficient solutions, transforming the device into a drug delivery system capable of releasing some drugs or bioactive substances is investigated. The main challenges are firstly to chemically modify such inert materials with soft methods in order to keep their original properties, and secondly to adsorb a sufficient therapeutic dose of the drug that should then be released covering the critical healing period. The concept developed by the UMET laboratory consists of grafting cyclodextrins on several biomaterials for extended drug release. This work presents an evolution of this latter concept thanks to the Layer-by-Layer process. Multilayer assemblies are built on a textile support thanks to alternative adsorptions of polyelectrolytes with opposite charges. It forms a multilayer coating on the fibers which allows the extended release of active molecules. Our multilayer system is based on an anionic polymer of β-cyclodextrin and chitosan (cationic polymer). Multilayer building optimization following the LbL process was simultaneously studied with Optical Waveguide Lightmode Spectroscopy (OWLS) and on textile. Its degradation and release of actives model molecules were followed in different media and biological and microbiological properties were studied

Full textIn this work we were interested in demonstrating some of the potentialities of electrochemistry on nanostructured surfaces in the field of plasmonics and in the realization of atomic contacts. The first chapter of this manuscript describes the creation of active plasmonic devices. It underlines how the redox properties of conducting polymers can modulate and/or commutate localized surface plasmon resonances of gold nanoparticles (network or colloidal solution). In the second part, an engraving System assisted by Atomic Force Microscopy (AFM) was developed. This technique allows the production of varied structures, on sub-micrometric and nanometric scales, for applications in the field of plasmonics and for nanoscale electrochemistry. The last part shows how electrochemistry can be used to obtain atomic contacts. The phenomenon of quantum conductance was studied on contacts obtained with copper nanowires and its variations with molecular adsorption were demonstrated. To protect the contact and to make it more stable, the use of cyclodextrins in the electrolytic growth medium appears to lead to its encapsulation and protects it against molecules interacting strongly with copper
