ABSTRACT:
The compound ortho-methoxyaniline (o-anisidine) can be polymerized by both chemical and electrochemical means to produce polyanisidine, a soluble polymer of high electrical conductivity. Also called poly-o-methoxyaniline or PANIS, polyanisidine can be further blended with various other polymers enabling construction of devices with desirable electrical, optical and physical properties. Oxidative polymerization yields have been increased to 47 percent with no apparent loss in electrical conductivity. PANIS has been blended with polystyrene, polyacrylonitrile, polyethylene oxide and poly(trimethyl hexamethylene terephthalamide) (nylon) to form free-standing, stable, flexible films and fibers having electrical resistance values dependent upon the concentration of PANIS. The applicability of PANIS technology has been demonstrated with the construction of three devices: a switching device that will change color upon the application of positive and negative voltages, an inert polymer electrode, and an electromagnetically shielded connector.
