丙烯酸氟烷基酯聚合物涂膜憎水性能研究

Study on the hydrophobicity of fluoroalkyl acrylate polymers film

分析了合成丙烯酸氟烷基酯所需的各类单体及其各自在共聚物中所发挥的作用,描述了憎水表面的形成过程,重点分析了侧链结构对聚合物涂膜憎水稳定性的影响。提出通过分子设计,选择恰当的氟烷基侧链、无氟烷基侧链以及间隔链,通过表面结晶或交联的方法来限制表面结构重组,从而提高其憎水稳定性。

The monomers used to synthesize fluoroalkyl acrylate polymers and their effects on the copolymers properities were analyzed, respectively. The formation of hydrophobic surface was described, and the emphasis was given to the influence of the structure of side chains on the hydrophobic stability of the film. Molecular design was proposed, that is, by chasing proper fluoroalkyl side chains, fluorine-free alkyl chains and space chains, the surface rearrangement can be restricted through crystallization or crosslinkage on the top surface, hence the hydrophobic stability of the film can be improved.
