一般說明

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。

應用

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

Fibrous scaffolds are used for bone tissue engineering purposes with great success across a variety of polymers with different physical and chemical properties. It is now evident that the correct degree of curvature promotes increased cytoskeletal tension on osteoprogenitors leading

文章

Professor Aran (Claremont University, USA) thoroughly discusses the engineering of graphene based materials through careful functionalization of graphene oxide, a solution processable form of graphene.

Developed in the last several years, fluorescence quenching microscopy (FQM) has enabled rapid, inexpensive, and high-fidelity visualization of two-dimensional (2D) materials such as graphene-based sheets and MoS2.
