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。

Properties and Applications of Functionalized Graphene Oxide

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.

Recent Trends in Self-Healing Soft Electronic Materials and Devices

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.

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.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).
