一般說明

丙烯酸是一种不饱和羧酸,碳氧之间的活性双键结构令其成为化学工业中常用的多功能合成砌块。它可制成各种丙烯酸类聚合物,这些聚合物可用作胶粘剂、油漆&涂料、医疗器械、有机半导体、薄膜晶体管、水凝胶和锂离子电池。此外,丙烯酸也用作自组装高分子制氢膜的聚电解质。

應用

丙烯酸主要用作单体合成各种丙烯酸聚合物,包括聚丙烯酸、聚甲基丙烯酸甲酯(PMMA)、丙烯腈-丁二烯-苯乙烯(ABS)等。这些聚合物具有各种优异性能,包括透明、耐刮擦、柔性、防水和耐化学品,用途广泛。丙烯酸也用作超吸水聚合物(SAP)的主要合成成分。这种聚合物可快速吸收并保留大量水。这一独特性能令SAP广泛用于多个领域,包括药物递送体系、化学工业和个人护理等。

丙烯酸的其他用途:
  • 用作重要组分制备共聚物粘合剂,以优化锂离子电池性能。
  • 聚丙烯酸可用作碳纳米管的表面改性剂,提高氧化物半导体基体中纳米管的粘合性和分散性,用于薄膜晶体管。
  • 用作活性单体,与乙二醇二甲基丙烯酸酯通过同步聚合法表面修饰聚二甲基硅氧烷(PDMS)。改性后的PDMS可用于微流控或生物医疗器械等新领域。
  • 用作前体,经由共聚反应合成腰果胶(cashew gum)/丙烯酸纳米粒子。丙烯酸可将亲水官能团引入腰果胶骨架,提高其水溶性及其它亲水材料的相容性。
丙烯酸可用于制备单分散聚N-异丙基丙烯酰胺(PNIPAM)/丙烯酸微凝胶。AAc经血浆沉积至表面,用于细胞培养应用。通过紫外诱导AAc接枝共聚,对聚(对苯二甲酸乙二醇酯)(PET)膜进行表面改性。AAc主要被用作丙烯酸酯生产的中间体。

Surface modification of argon-plasma-pretreated poly(ethylene terephthalate) (PET) films via UV-induced graft copolymerization with acrylic acid (AAc) was carried out. Galactosylated surfaces were then obtained by coupling a galactose derivative (1-O-(6'-aminohexyl)-D-galactopyranoside) to the AAc graft chains with the aid of a
