Preparation of ZnS Modified PHBV Film by Chemical Bath Deposition Method

摘要

Zinc nitrate hexahydrate, ethylene glycol, thiourea and triethanolamine were purchased to be starting materials. Nano zinc sulfide solution has been successfully prepared by Chemical bath deposition method, and then the prepared zinc sulfide modified polyhydroxybutyrate valerate (PHBV) to form the thin film. The morphology, structure, transparency and luminescent properties of the prototype were characterized by X-ray diffraction, UV-visible spectrophotometer, polarized light microscopy, scanning differential thermal balance and fluorescence spectrophotometer. The results show that ZnS is the presence of a nucleating agent in the PHBV. With the zinc sulfide modified PHBV, the nucleation density and the toughness of the film can be improved while the composite film have fluorescence. But the addition of zinc sulfide can not change the crystal structure of PHBV films which will reduce the thermal stability of PHBV and inhibit the process of crystallization.
