产品介绍 |
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 General Description Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index of 1.49. Hence, it is used in optical fibers.It finds uses in biological applications because of its lower water absorption capability and biocompatible.The maximum moisture content of PMMA is 1.71% and SBF absorption is 1.96%.Simulated Body fluid test (SBF) is a method to characterize the in vitro bioactivity of ceramic materials, by immersing the materials in an aqueous SBF solution. Application PMMA/HA (Hydroxyapatite) composites have been used in biomedical applications such as dentistry, orthopedic retainers, and bone replacement. It is used as substrate for graphene growth. Some studies report its use in PMMA-titania hybrid optical thins films PMMA/polystryrene/clay nanocomposites PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells |
