一种多功能有机蒙脱土-纳米TiO2/环氧树脂复合材料

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-nano TiO2/epoxy composites

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.
