一般描述

聚(甲基丙烯酸甲酯)(PMMA)是无定形、透明的热塑性聚合物。PMMA 的折射率为 1.49 ,因而被认为是光学聚合物。因此,它被用于光纤。由于其较低的吸水能力和生物相容性,它在生物应用中得到应用。PMMA 的最大含水量为 1.71%,SBF 吸收率为 1.96%。模拟体液试验(SBF)是一种通过将材料浸入 SBF 水溶液中来表征陶瓷材料的体外生物活性的方法。

应用

PMMA/HA(羟基磷灰石)复合材料已经用于生物医学应用,例如牙科、矫形保持器和骨替代物。它用作石墨烯生长的基质。
一些研究报告它用于
PMMA-二氧化钛杂化光学薄膜
PMMA /聚苯乙烯/粘土纳米复合材料
用于甲醇燃料电池的 PMMA /聚氨酯/炭黑纳米复合材料
