Transient behavior of electrical conductivity in low‐density polyethylene in the presence of acetophenone

Abstract

The transient current in low-density polyethylene (LDPE) is studied, particularly in the presence of the small organic molecule acetophenone (ACP). Crosslinked LDPE is used extensively in high-voltage power transmission, and acetophenone is a common byproduct of the crosslinking chemistry. Timedependent current measurements of LDPE with and without ACP soaked into the polymer as well as at one or both electrodes are performed by applying step
