聚硅氧烷性能优异,如表面能低、优异的热稳定性、低温柔顺性和气体与水汽渗透性等。由于分子间的作用力较弱,聚硅氧烷力学性能欠佳,在某些领域的应用受到了限制。聚硅氧烷与有机聚合物或无机高分子形成互穿聚合物网络,不仅可以弥补聚硅氧烷在力学性能的不足,且能改善有机聚合物或无机高分子的表面特性、传输性质和柔顺性等性能,使互穿聚合物网络兼有两者的独特性能。本文较详细论述了几类主要的聚硅氧烷互穿聚合物网络的研究状况与应用,并展望未来的发展方向。
Polysiloxane performance, such as low surface energy, excellent thermal stability, low temperature compliance and gas and water vapor permeability and so on. Due to the weak intermolecular forces, the mechanical properties of polysiloxanes are poor, and the application in some fields is limited. Polysiloxane and organic polymers or inorganic polymers to form interpenetrating polymer network, not only make up for lack of mechanical properties of polysiloxane, and can improve the organic polymer or inorganic polymer surface properties, transmission properties and compliance Sexual performance, so that the interpenetrating polymer network both the unique performance. This paper discusses in more detail the research status and applications of several major types of polysiloxane interpenetrating polymer networks, and looks forward to the future direction of development.
