一种多功能有机蒙脱土-纳米TiO2/环氧树脂复合材料
|
Abstract:
将有机蒙脱土（O-MMT）和纳米TiO2共同复合到环氧树脂中，成功地制备出了一种高性能多功能O-MMT-纳米TiO2/环氧树脂复合材料。由XRD检测结果和TEM观察结果证实，由于利用了O-MMT、纳米TiO2与环氧树脂间的相互作用，蒙脱土（MMT）层被高度剥离，所得的二维MMT纳米单片与零维纳米TiO2颗粒交错分布于树脂基体中。力学性能测试、热分析和耐沾污性试验表明，O-MMT-纳米TiO2/环氧树脂复合材料的多项性能都比纯环氧树脂有大幅提高。 Versatile high-performance organo-montmorillonite (O-MMT)-nano TiO2/epoxy composite was successfully prepared by co-incorporating O-MMT and nano TiO2 into the epoxy matrix. XRD and TEM reveale that in O-MMT-nano TiO2/epoxy composites, montmorillonite (MMT) layers are highly exfoliated into nanoscale MMT mono-platelets by the strong interaction among O-MMT, nano TiO2 and epoxy, and the 2D MMT mono-platelets take an interlacing arrangement with the 0D nano TiO2 particles in the epoxy matrix. The mechanical tests, thermal analyses and test for dirt pickup resistance and stain removal show that the resulting O-MMT-nano TiO2/epoxy composite obtain considerable improvements over the pure epoxy in multiple properties. This study suggests that co-incorporation of proper, dimensionally different nanoscale particles into polymer matrices is a successful way for preparing versatile high-performance polymer composites. “十三五”装备预先研究项目（10204010307）；海军工程大学理学院基础研究基金（HGDLXY17ZK004）
