Abstract

It is reported in this paper that waterborne polyurethane (WPU) can be modified by nanopolyphosphazenes fibers, which had benn prepared containing hydroxyl groups, followed by reaction with WPU. At the same time, physical blends had also been carried out in the experiments. The results showed that the tensile strength of the WPU films through chemical modification containing 0.5 wt% fibers is 1.22 MPa, and that the elongation at break is 1294.50%. This data have significantly increased when compared against WPU, in which the elongation at break is only 785.50%. The thermal decomposition temperature of the WPU modified by nanopolyphosphazenes is 50 % higher than that of WPU. At the same time, its preparation method had some influences on the mechanical properties of the composite materials.
纳米聚磷腈改性WPU的制备及性能研究
研究了用含羟基纳米聚磷腈纤维对水性聚氨酯(WPU)进行改性的方法。同时,还进行了物理共混实验。结果表明,含0.5 wt%纤维的化学改性后的WPU薄膜拉伸强度为1.22 MPa,断裂伸长率为1294.50%。与WPU相比,这一数据显著增加,WPU的断裂伸长率仅为785.50%。纳米聚磷腈改性后的WPU热分解温度比WPU高50%。同时,其制备方法对复合材料的力学性能也有一定的影响。
