采用一种简单、节能、适合工业化生产的工艺制备了含有自组装二维胶体α-磷酸锆纳米片（ZrP）的环氧树脂薄膜。ZrP纳米片在环氧树脂中形成同时具有层状有序和螺旋排列的手性近晶中间相。该环氧纳米复合材料薄膜是透明和柔性的，并表现出非常高的拉伸模量和强度。这些发现对开发工程应用的多功能材料具有广泛的意义。
Epoxy films containing self-assembled 2D colloidal a-zirconium phosphate nanoplatelets (ZrP) in smectic order were prepared using a simple, energy-efficient fabrication process suitable to industrial processing. The ZrP nanoplatelets form a chiral smectic mesophase with simultaneous lamellar order and helical arrangements in epoxy. The epoxy nanocomposite films are transparent and flexible and exhibit exceptionally high tensile modulus and strength. The findings have broad implications for development of multifunctional materials for engineering applications.
