氟、硅改性聚氨酯材料的研究进展

Progress on fluorine and silicon chemical modification of polyurethane

聚氨酯(PU)是一类用途广泛的工程材料,但用传统原料和方法制备的聚氨酯也存在诸多缺点,如耐热性、耐侯型不好,从而限制了它在工程技术领域的进一步应用。为此,聚氨酯的化学改性成为该领域的研究热点之一。作者综述了近年来氟、硅化学改性聚氨酯方面的研究进展,并对今后的研究发展进行展望。

The polyurethane（PU）is a kind of engineering materials tional way of making polyurethane has some disadvantages, such as ance, so it sets bounds to its further application in engineering. This and silicon chemical modification of polyurethane. with broad applications. The tradi heat resistance and weather resist review has a closer look at fluorine
