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.
