| Summary: | 碩士 === 萬能科技大學 === 工程科技研究所 === 95 === The conductivity of poly(3,4-ethylenedioxythiophene)(PEDOT) doped with poly(4-styrenesulfonate) (PSS) containing various organic solvents was measured. The solvents used were isopropanol [IPA,(A)], N-methyl-2-pyrrolidone [NMP(B)], N,N-dimethyl acetamide [DMAC(C)],dimethyl sulfoxide [DMSO(D)] with concentration 25wt% and 50wt%, respectively. It was found that an addition of organic solvent. lower resistance by one or three orders of magnitude when the concentration was used by 25wt% . The PEDOT/PSS films have been studied using four point probe conductivity meter, X-ray diffractometry (XRD), fourier transform infrared (FTIR), thermogravimetric analysis(TGA) in order to discuss the conductivity the crystallity the chemical structure and the thermal properties of the PEDOT/PSS film. Conducting PEDOT/PSS-IPA/DMSO(AD25) solution mixed with polymethyl- methacrylate(PMMA) resin to coat hydrophobic fabrics, which can be used for the dissipation of electrostatic charge. We design different screen patterns (square, circle, cross, triangle) and utilize it coating PET fabrics, Nylon fabrics and Acrylic fabrics, witch are subjected to electric conductivity and electrostatic discharge. Attenuation of the electrostatic discharge (ESD) for various pattern shape be described. The ESD behavior was also related to a percolation area, it was proofed that a ESD effect of pattern with covered area (connected pattern) was higher than that of less covered area (separated pattern). Finally we selected the best connected pattern shape and prescription to coat hydrophobic fabrics.Obviously, the more shorter decay time , the charge dissipation more faster. This thesis could apply to printing pattern design and could achieve not only antistatic charge but also reduce cost, It is very helpful to textile industry and soon.
