A facile method using nano-particles to control the surface structure and the wettability was reported.Three kinds of pofy(vinyl chloride) (PVC) films with different surface structure were prepared by the imprinting of nanosilicas.The wettability studies of these films showed that the contact angle for water was changed from 103°to 65°.then improved to 130°.The PVC film surface was examinated by using a scanning electronic microscope.It was showed that the PVC film surface had nanoholes and nanoprotmdings structure after being imprinted with nanosilicas
and the parallel experiments proved that chloroform and NaOH solutions could not improve the wettability of PVC films.
