Изменения контактного угла смачиваемости ПЭТФ трековых мембран после автоклавирования

Abstract

Wettability has been recognized as one of the most important properties of membranes for both fundamental and practical applications. Water adsorptions were used to evaluate the wetting behavior of the polyethyleneterephthalate (PET) track membranes. The experimental results revealed that the wettablity and contact angle of the PET track membranes were significantly affected by autoclaving. The steam sterilization method increases the hydrophobicity of the membrane surface. The interaction sterilized membrane with air increases surface wetting ability by means of the formation of hydroxyl groups.
