摘要
综述了聚硅氧烷聚氨酯中含硅链段的主要引入方法,即分别由聚氨酯软段引入、聚氨酯硬段引入,并对各自的优缺点进行了评述。阐明了聚硅氧烷聚氨酯乳液的稳定性、材料的微相分离与表面形态、耐水性及低表面能、机械性能、耐热性和生物相容性等性能及其影响因素,并指出了国内外聚硅氧烷聚氨酯的研究热点和发展方向。
The general methods of preparing poly(siloxane-urethane) were reviewed,especially the introducing of siloxane-containing group to the hard-segment of polyurethane,soft-segment of polyurethane.The advantages and disadvantages of each method were alsodiscussed.Typical properties of poly(siloxane-urethane) were presented.,such as stability of the emulsion,mirophase-separation and surface morphology,water resistant and low surface energy physical-mechanical,thermal stability and biocompatibility.The future deve...
