摘要
Polyvinylidene fluoride nanofibers were treated by dimethylformamide to create micropores on membrane surface. Photocatalysts were firmly bounded by nanofibers during stretching and shrinking. Particulate catalysts were fixed yet high exposed on the membrane surface. Surface self-bounded photocatalytic membrane exhibited tenfold higher decontamination activity than embedded catalyst.
