摘要:
将凹凸棒土(ATP)和氨基化凹凸棒土(ATP-NH2)填充于聚偏氟乙烯(PVDF),制备了PVDF/ATP和PVDF/ATP-NH2复合材料。利用偏光显微镜(POM)观察复合材料中PVDF的结晶形态,傅里叶变换红外(FTIR)鉴定了PVDF的晶型,差示扫描量热法(DSC)分析了PVDF的熔融结晶行为。结果表明,ATP和ATP-NH2对PVDF晶型没有影响。PVDF/ATP复合材料中,由于相容性较差,PVDF球晶尺寸不均一,出现双熔融峰。即使当ATP含量为2%时,球晶尺寸仅略微减小且分布不均。ATP-NH2与PVDF相容性明显改善,起到了成核剂的作用,生成尺寸均一的PVDF小球晶,且熔融峰为单一熔融峰、熔限较窄。少量ATP-NH2(w=0.5%)对PVDF成核作用明显。随着ATP-NH2含量的增加,成核作用增强。
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 observed 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 calorimeter(DSC). The results showed that both ATP and ATP-NH2had 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 nucleation effect was enhanced by the increase of addition of ATP-NH2.
