PVA microfibrils were gold coated by sputtering at 140 and 150 W for 1, 2, and 3 minutes, respectively. Weight gain by gold atoms reached up to 7% for PVA microfibril treated at 150 W for 3 minutes. Morphological changes at surface were observed by microscopic method and the mechanism of gold coating on PVA microfibril was suggested.
