凹凸棒土对聚偏氟乙烯结晶行为的影响
The Effect of Attapulgite on Crystallization Behavior of Poly (vinylidene fluoride)
摘要
Abstract
Attapulgite (ATP)and amino-functionalized attapulgite (ATP-NH2 )were used to prepare poly (vinylidenefluoride)(PVDF)/ATP and PVDF)/ATP-NH2 composites.The spherulite morphology was ob-served by polarized optical microscopy (POM).Crystal form were identified by Fourier transform infrared spectroscopy (FTIR).The melting and crystallization behaviors were detected by differential scanning cal-orimeter (DSC).The results showed that both ATP and ATP-NH2 had no effect on the final crystalline form of PVDF crystal.In PVDF/ATP composites,un-uniform size spherulites formed and double melting peaks were observed because of bad miscibility.Even when 2% ATP was added in the PVDF composite,a little small decrease of the spherulites was observed.These spherulites were not dispersed well.In the case of ATP-NH2 ,the miscibility with PVDF chains was better than ATP.Thus,it had a good nucleation effect on the PVDF crystallization,leading to a uniform size spherulites and sharp single melting peak. Small addition of w=0.5% ATP-NH2 had a good nucleation effect on PVDF crystallization.This nuclea-tion effect was enhanced by the increase of addition of ATP-NH2 .关键词
