冷冻处理凹凸棒黏土对PVA/APT纳米复合膜性能的影响
Effects of Freeze Treated Attapulgite on Properties of PVA/APT Nanocomposite Films
摘要
Abstract
Poly (vinyl alcohol )/attapulgite (PVA/APT) nanocomposite films containing freeze process treated APT were prepared using film-casting method. The microstructures of the nanocomposite films were investigated using SEM, FTIR and XRD. The mechanical properties and water resistance of the nanocomposite films were also tested. The experimental results indicate that frozen APT can be dispersed better in PVA matrix than APT not treated by freeze process, thus mechanical properties and water-resistance of the nanocomposite films have been significantly improved. When adding APT with freeze treated 16 h, the nanocomposite film has optimum performances. The tensile strength, elongation at break and water resistance have an increase of 17.4% , 25.4% and 19.2% , respectively.关键词
