摘    要:采用本体聚合法制备了纳米AgBr/PMMA(聚甲基丙烯酸甲酯)光致变色杂化材料. XRD分析表明,纳米AgBr/PMMA杂化材料是无定形的. SEM分析表明, AgBr含量不同,杂化材料的断面形貌明显不同,随AgBr含量的增加,杂化材料由韧性断裂向脆性断裂转变. EDS面分析表明, Ag、Br元素在杂化材料中均匀分布.所制备的纳米AgBr/PMMA杂化材料具有一定的光致变色效应.

关 键 词:AgBr  聚甲基丙烯酸甲酯(PMMA)  纳米材料  杂化材料  光致变色

Abstract:Nanosized AgBr/PMMA hybrid material of photochromism was synthesized byin situ polymerization. XRD analyses indicate that the nanosized AgBr/PMMA hybrid materials are amorphous. SEM analyses show that the morphology of the hybrid material varies with the AgBr content in the hybrid materials, and the tenacity fracture of the hybrid material changes into fragility fracture with the increase of AgBr content. EDS reveals that the distributions of both elements of Ag and Br in the hybrid material are homogeneous. The nanosized AgBr/PMMA hybrid material has a photochromic effect.
Keywords:AgBr  PMMA(polymethylmethacrylate)  Nanomaterial  Hybrid material  Photochromism
