PES/PCz kompozitinin sentezlenmesi ve karakterizasyonu

In recent years, conductive polymers have been used in various field and become an important alternate instead of metals. This approach causes an increase in improvement regarding conductive polymers. Conductive polymers are used as body area network (BAN), antenna, sensor, electrode, cathode material obtained by coating onto PET and glass, electrocardiography (ECG), electromiyography (EMG), electromagnetic shielding applications in military and on the sports field. Conductive textiles are one of the applications of conductive polymers. Polypyrrole (PPy), polyaniline (PANi), polythiophene (PTh), polydioxythiophene(PEDOT):paratoluenesulphonicacid(PTSA), PEDOT:PSS copolymers and Poly(3-methyl thiophene) (P3MTh) nano application are within application of conductive polymers. In this study, it is aimed to synthesize PCz by in situ polymerization onto polyester (PES) textile substrate with using different oxidants and solvents. Most studies have been focused on in situ polymerization to produce conductive textile since this method does not require the destruction of the substrate and provides reasonably good conductivity. The final form of PCz is that of a long conjugated backbone. The polymer has resonance structures. In this neutral state the polymer is not conducting and only becomes conducting when it is oxidized. FeCl3 and CAN were used as oxidant. Acetonitrile (ACN), water and toluene was used as solvent. It was investigated the effects of different concentration of monomer, oxidant, solvent and polymerization time and also the order of immersion of Cz monomer and oxidant solutions to electrical conductivity. Electrical conductivities and capasitive values were measured by disc probe. PES/PCz composites were characterized by Color analysis, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), Dynamical Mechanical Analysis (DMA) methods. As a result, PCz was coated onto PES tekstile in the presence of FeCl3 and PES/PCz composites were obtained with 0.32 Ω electrical resistance.
