- 通过共聚反应合成甲基丙烯酰化软骨素硫酸盐pH敏感水凝胶。这些水凝胶可用于药物传递系统。
- 高性能木质素基热固性树脂。
- 凝胶聚合物电解质，然后与阴极集成以形成高性能锂离子电池。
General description
甲基丙烯酸酐是一种有机化合物，来源于甲基丙烯酸，属于丙烯酸类。它主要用作聚合物的单体，特别是聚（甲基丙烯酸）及其共聚物的生产中。由于其优异的化学和热稳定性，这些聚合物在广泛的行业中应用，包括生物可再生树脂、pH敏感水凝胶、热固性树脂、涂料、胶粘剂和塑料。在甲基丙烯酸酐的聚合过程中，最常用的抑制剂是Topanol A。通常以小量（2000 ppm）添加，以阻止在聚合过程中不良的副反应，确保受控和高质量的聚合物形成。

A PCL/hydrogel construct that would mimic the structural organization, biochemistry and anatomy of meniscus was engineered. The compressive (380 ± 40 kPa) and tensile modulus (18.2 ± 0.9 MPa) of the PCL scaffolds were increased significantly when constructs were printed with a shifted design and circumferential
