Electric Field -Induced Surface Morphology in a Copolymer of Vinylidene Cyanide and Vinyl Acetate
We investigated the surface morphology of the film of a copolymer of vinylidene cyanide and vinyl acetate, using atomic force microscopy. It was found that when a high electric field is imposed to the film near its glass transition temperature, a thin fiber–like assembly about 10 nm thick appears on the surface. The surface structure was discussed relating to the relatively high piezoelectricity in this amorphous–type polymer.
