一般描述

N,N-二甲基丙烯酰胺(DMAA)是一种非离子单体,具有高反应性和低起始温度。它通常被用作聚合物和共聚物的单体,用于各种应用,如水凝胶、高分子絮凝剂、生物医学和药物传递应用、聚合物涂层、智能涂层、胶粘剂、传感器、自修复材料和水处理剂。DMMA独特的结构可与其他水凝胶形成三维网络,增强它们的保水能力。它还被用作聚合反应中的交联剂。

应用

N, N-二甲基丙烯酰胺(DMAA)可用于以下应用领域:
  • 合成聚(N,N-二甲基丙烯酰胺(PDMAA)纳米颗粒,用于生物医学和药物传递应用。
  • 作为共聚单体,用于合成在智能涂层、胶粘剂和传感器中使用的热响应性聚合物。
  • 作为紫外线固化涂料和油墨的制造中的反应性稀释剂。
  • 与聚乙二醇二甲基丙烯酸酯(PEGDMA)和壳聚糖衍生物一起作为共聚单体,用于开发可注射的水凝胶,可用作骨组织工程基质。
  • 一系列基于DMMA的水凝胶,用于从污染水中去除重金属和有机染料。由于静电作用以及DMMA主链中的氢键结合作用,这些水凝胶在去除阳离子染料方面具有较高的效率。
  • 通过表面引发逆加成-断裂链转移聚合合成无毒发光碳点/聚(DMMA)纳米复合材料。
  • 用于石英晶体微天平(QCM)传感器的聚合物涂层。聚(DMMA)凝胶作为一种敏感材料,从盐酸水溶液中吸附Au(III)离子,对大多数其他金属离子和有机化合物无活性。

特点和优势

  • 由于具有起始温度低和反应性高的特性,它适用于共聚作用的前体。
  • 独特的结构形成三维网络,提高了水凝胶的保水性能。
  • 极易溶于水。
  • 易于与胶粒结合,增强桥联效应,在絮凝作用中起着关键作用。

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
