AAc photografted porous polycabonate films and its controlled release system.
The AAc grafted porous PC film was prepared by simultaneous UV irradiation and the pH sensitivity of the grafted films was investigated with the simple controlled release device designed by the authors. The grafted porous PC films showed remarkable pH sensitivity and can be reused after proper treatment.
