Method of sulfonation of polymer substrate to impart a hydrophilic layer in said substrate with improvement in at least one of anti-fog, anti-static, wettability, lubricity anti-microbial properties, and articles made thereby

摘要

A sulfonation method to treat a polymer substrate to provide a hydrophilic layer with an improvement in at least one of anti-fogging, anti-static, wettability, lubricity, anti-microbial and/or transparency properties. The articles formed thereby find excellent application in a wide range of areas.
