一般說明

聚甲基丙烯酸甲酯 (PMMA) 是一种非晶态透明热塑性聚合物。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。它的低吸水性和良好生物相容性使其在生物领域得到广泛应用。PMMA 的最大含水率为 1.71%，SBF 吸收率为 1.96%。模拟体液测试 (SBF) 是一种通过将陶瓷材料浸入 SBF 水溶液中来表征其体外生物活性的方法。

應用

PMMA/HA（羟基磷灰石）复合材料已应用于牙科、矫形固位器和骨置换等生物医学领域。它被用作石墨烯生长的基质。
一些研究报告其可用作
PMMA-二氧化钛杂化薄膜
聚甲基丙烯酸甲酯/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。

A new AgNW-graphene hybrid transparent conducting electrode (TCE) was prepared by dry-transferring a chemical vapor deposition (CVD)-grown monolayer graphene onto a pristine AgNW TCE. The AgNW-graphene hybrid TCE exhibited excellent optical and electrical properties as well as mechanical flexibility. The

Fluorescence Quenching Microscopy: Imaging Two-Dimensional Materials

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.

A Review of Mesoporous TiO2 Thin Films

In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes. Specifically, we focus on recent developments in TiO2 mesoporous thin films in a combined sol-gel and evaporation-induced self-assembly (EISA) process.
