This study is synthesizing conductive polymers with high strength and processibility. The polyaniline was coplymerized with polyurethane prepolymer to form polyurea copolymer. The resultant conductive polymer was more soluble and had better processability. The number average molecular weight of the prepared polyaniline was 1380 according to the GPC analysis. It can be dissolved in NMP up to 5wt%. After doping with high concentration HCl, the conductivity of 0.83 S/cm is obtained. It approaches the conductivity of polyaniline with high molecular weight. Two processes for copolymerizing polyaniline and polyurethane prepolymer have been performed in the experiment. For the process I, the maximum tensile strength of the copolymer is 42.7MPa. The maximum conductivity is 0.18 S/cm, which is in the conductive range of semiconductor (10-7~102 S/cm). From the TGA study, the thermostability is improved by increasing polyaniline content. From the DSC and DMA study, the glass transition temperature (Tg) raises with the increase of the amount of polyaniline. For the process II, the result is similar to the polymer blend. And the conductivity is 10-6~10-5 S/cm. Keyword: Polyaniline, Polyurethane, Copolymer, Conducting polymer.

Chitosan is widely used in biomedical applications due to its antibacterial property. However, the antibacterial activity of chitosan significantly reducesat physiological pH (7.4). In the study, [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETMAC) was grafted onto chitosan using ammonium sulfate (APS) as a redox initiator to improve its antibacterial activity in neutralpH. The effects of APS and AETMAC concentrations and reaction temperature on graftingpercentage and grafting efficiency were studied.Theincorporation of AETMAC into chitosan chains was confirmed by Fourier transforminfrared (FTIR) spectroscopy.The effects of grafting on thedegree of crystallinity, solubility, water absorbance ratio, water vapor transmissionrate (WVTR) and antibacterial activity of graft copolymer (CS-g-PAETMAC) membraneswere investigated. The results showed that the graftingpercentage and grafting efficiency increased with increasing the concentration of APS and reaction temperature. Moreover, the grafting efficiency decreased with increasing the concentration of AETMAC. CS-g-PAETMAC had a higher graftingpercentage when the concentration of AETMAC was 0.15 M. FTIR spectra confirmed the formation of graft copolymer and thefact by increasing the amount of AETMAC in the feed mixture, the amount ofincorporation AETMAC in the graft copolymers increased.X-Ray diffraction exhibited that the grafting of AETMAC disturbed the crystalline structure of chitosan. Additionally, the CS-g-PAETMAC membrane has a higher solubility in pH 5.0 and pH 7.4 solutions, water absorbance ratio and WVTR than pure chitosan membrane. Moreover, the higher the concentration of AETMAC, the higher were solubility, water absorbance ratio and WVTR.Finally, the antibacterial activity of the chitosan membranes wasperformed by inhibition zone method against Staphylococcus aureus. It demonstrated a distinct inhibition zoneadjacent to CS-g-PAETMAC membrane when the concentration of AETMAC was higher than 0.15 M. However, it was not observed around the pure chitosan membrane. Therefore, the CS-g-PAETMACmembranehas the potential for wound-dressing application.

Chondroitin sulfate(CS)is one of the polysaccharide in nature and has been used as a biomaterial widely because of biocompatibility, nontoxicity and highly enzymatic hydrolysis. Therefore to prepare CS hydrogel, which can be used to sustain drug release well is of great interest. Since the natural CS is highly water soluble, which may not maintain as a solid form in the human physiological condition, therefore the incorporation of methacrylate (MA) groups on CS side chain to introduce the double bonds, which can further polymerized with any vinyl monomers to form hydrogels. Three degrees of substitution (DS) determined by 1H-NMR were prepared in the order of 75%, 45%, and 20% respectively. These CS-MAs are further copolymerized with acrylic acid as a molar ratio of 1: 5 to form hydrogels. The enzymatic degradation by GPC and the drug-released behavior by HPLC will be traced. The compression modulus evaluated by material testing machine and hydrogel morphology observed by scanning electron microscope will be presented in this article. Finally, the potentially sustain-released efficiency of these hydrogels will be tested using the BSA as a protein model drug.

This study used various instruments to analyze and identify the properties and crystallization behavior of a series of Polybutylene terephthalate/Polytetramethylene Ether Glycol thermoplastic Polyester Elastomer (TPEE) synthesized in this laboratory. The first part is the identification of components and properties. Firstly, the results of PBT and PTMEG copolymerization were confirmed by FTIR and NMR spectroscopy. The actual peak ratio of PTMEG in each material was calculated from the corresponding characteristic peak area of NMR spectrum. When the Tg point was tested by DMA, it was found that the Tg point decreased significantly with the increase of PTMEG content. The same trend appeared when the Tm test by DSC. Indicating that the softness of the whole molecular chain was obtained with the increase of the soft chain PTMEG content And the Tm and Tg decrease. However, there was no significant difference between pure PBT and other copolymers at the Td test (5%) by TGA, indicating that the initial cracking step was dominated by the hard segment PBT. The second part is non-isothermal crystallization kinetics. The temperature is raised and lowered by DSC at 2, 5, 10, 20 °C/min. The crystallization curve is observed. It is found that under the same cooling condition, when the proportion of PTMEG increases, the temperature range of the crystallization peak was lowered. And then analyzed and compared using the Avrami and Mo models, and the crystallization activation energy was calculated by the Kissinger equation. The third part is a temperature-controlled hot plate with a polarizing microscope to make the materials isothermally crystallize and observe the behavior and crystallization rate changes. Similar to the DSC non-isothermal crystallization, at the same temperature, the crystal growth rate decreases as the PTMEG content increases. The crystal morphology, with the increase of PTMEG content, the more obvious the color of negative spherulite field. Indicating that the soft segment increases the flexibility of the molecular chain, and the stack is more regular. In the same material, as the crystallization temperature increases, the molecular chain kinetic energy is enhanced and it is difficult to form a stack, the color different becomes inconspicuous, and the shape of the crystal deviates from the spherical shape.
