Transparent, anti-static coating on poly substrate (methyl methacrylate)

Abstract:
In this research, by spin coating, a layer of conductive poly(3,4-ethylene dioxythiophene)(PEDOT) synthesized via in situ polymerization of 3,4-ethylene dioxythiophene(EDOT) was coated on poly(methyl methacrylate)(PMMA) substrate. The effect of different factors such as time and temperature of curing, speed of spin coating on the structural, electrical and mechanical properties of coated layer were characterized by FT-IR and UV-Vis spectroscopy, conductive measurements and tape test. The results revealed that a surface with good conductivity (61.38 kΩ) and excellent transparency with an excellent adhesion was obtained which can be useful for anti-static application. Also these data show that the resistance of the prepared coating is less than 108Ω and since the decrease of polymer electrical resistance to108 Ω or less, can reduce the accumulation of static electricity on the surface of the polymer, therefore, this coating has the ability to reduce accumulation of static electricity.
