一般描述

聚(甲基丙烯酸甲酯)（PMMA）是一种无定形透明热塑性聚合物。PMMA的折射率为1.49，被认为是一种光学聚合物。因此，它被用于光纤中。由于它具有较低的吸水能力和生物相容性，因此，它被用于生物应用中。PMMA的最大含水量为1.71%，SBF吸收率为1.96%。模拟体液（SBF）测试方法通过将陶瓷材料浸入SBF水溶液中来鉴定材料的体外生物活性。

应用

PMMA可以用作石墨烯生长的基质。已有研究报道了将其用作
  • 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/碳黑纳米复合材料
  • 丙烯酸玻璃
  • 外科中的植入物
  • 作为垫片。
