Poly (ethylene terephthalate) (PET), nylon 6, and p-aramid films were sputter-etched with argon ions at a pressure of 0.1mmHg and their surfaces were examined by scanning electron microscopy. The uniaxially stretched PET and nylon 6 films showed a number of wavy crevices perpendicular to the stretching direction, whereas biaxially stretched PET and nylon 6 films produced many protrusions. Casted p-aramid film also produced the same protrusions.
