Preparation and characterization of conducting polymer coating on ABS substrate
Conducting polymer coatings on ABS were prepared by dipping them into m-cresol solutions containing polyaniline (PANI), poly(o-toluidine) (POT), and poly(o-anisidine) (PoAN) protonated with dioctyl hydrogen phosphate (DiOHP) in the presence and absence of polystyrene (PS). The surface resistivity of ABS plates coated with DiOHP-doped PANI in the presence and absence of PS were 5.3 X 10(7) and 3.0 x 10(5) Omega, respectively. The ABS plates coated with DiOHP-doped PoAN and -doped POT showed higher resistivities (4.2 x 10(9) and 2.4 x 10(7) Omega, respectively) than that with DiOHP-doped PANI. Although the conductivity of the coated ABS with DiOHP-doped PANI was less in the presence of PS, the permanency and uniformity of the coating, which are very important for practical use, were much improved. Coatings and the coated ABS were characterized by X-ray diffraction, TG/MS, SEM, and reduced viscosity measurements.
