纳米MoO3／PMMA杂化材料的制备与表征

Preparation and Characterization of Nanometer-Sized MoO3/PMMA Hybrid Material

摘要:

采用原位聚合法制各了纳米MoO3／PMMA杂化材料。XRD分析表明，杂化材料是无定形的。SEM分析表明，杂化材料中MoO3含量不同，材料的断面形貌明显不同，随MoO3含量的增加，杂化材料的脆性增加。EDS分析表明，Mo在杂化材料中的含量为1．09％（质量分数）。实验表明，随MoO3含量的增加，杂化材料的透过率和溶解性降低，材料的硬度和断裂强度均呈下降趋势。

Abstract:

The nano-sized MoO3/PMMA hybrid material was prepared by in-situ polymerization method. XRD patterns show that the hybrid material is amorphous. SEM indicates that the morphology of fracture plane of the hybrid material is different when MoO3 content is varied in the hybrid materials, and the fragility increase with the increase of MoO3 content. EDS reveals that the content of Mo is 1.09%. It is found that the transmissivity, solubility, hardness and fracture strength of the hybrid materials decrease with the increase of MoO3 content.
