Poly woven grafts

Alkaline zinc-Mn02 batteries generally employ macroporous non woven separators made from cellulose or synthetic fibers (poly(vinyl alcohol) (PVA), nylon, rayon, and so on). Attempts to improve separators have generally been unsuccessful. For rechargeable Zn-Mn02 batteries, the separators are made from cellophane, grafted membranes, or polymeric films.
