摘　　要：以甲胺为胶体化试剂,进而采用“层离-插层法”合成得到长链季铵盐十六烷基三甲基溴化铵(C16)／α-ZrP插层化合物(记为OZrP),并用XRD,TEM,SEM,IR等对其结构、形貌和疏水性等进行了表征和研究。结果显示,所获得的插层化合物OZrP保持有序的层状结构,层间距增大为2．9 nm,并具有良好的疏水性,是制备聚合物／α-ZrP纳米复合材料的优良前驱物。High-intensity ultrasound was applied to the intercalation process of a-zirconium phosphate （α-ZrP） with alkylamine, which can increase the reaction rate obviously. In this paper, methylamine was chosen as a colloidal reagent for the exfoliation of α-ZrP, the intercalated compound of hexadecyltrimethyl ammonium bromide（C 16） with α-ZrP, which could be abbreviated to OZrP, was prepared by ＂exfoliation-intercalation method＂, and its structure, morphology and hydrophobic property were characterized and investigated by XRD, TEM, SEM, IR. The results indicated that the OZrP retained layered structure with the d-spacing of 2.9nm. Interestingly, the OZrP presented well hydrophobic property, which may be used as a promising precursor for preparing polymer/α-ZrP nanocomposites.
