| 摘 要： | 采用不同浓度的聚甲基丙烯酸甲酯(PMMA)丙酮溶液对玻璃纤维进行表面处理，并对不同处理条件下的玻璃纤维表面化学组成、PMMA的吸附量及齿科树脂基复合材料的力学和界面性能进行了分析和测试。结果表明，经过表面处理，玻璃纤维表面吸附上PMMA，且吸附量随PMMA溶液浓度的增大而增大。控制玻纤表面吸附的PMMA质量分数在1%左右，可以设计其与齿科树脂形成半互穿网络结构的良好界面。与未处理的玻纤复合材料相比，用质量分数为5%的PMMA溶液处理的玻纤/光固化树脂基复合材料的弯曲强度提高29.6%，弯曲模量提高30%，可以作为一种齿科修复用的新型生物复合材料应用。

| Abstract: | Glass fibers were surface treated with polymethylmethacrylate(PMMA) acetone solutions of various concentrations.The amount of PMMA on glass fiber,surface nature of glass fibers and the interfacial and mechanical properties of the treated glass fiber/dental resin composites were investigated.The results show that PMMA polymer adhered to the glass fiber surface and the amount of PMMA on the glass fiber surface increases with increasing concentration of PMMA solution.By controlling the mass fraction of PMMA on... |
