制备了钛酸钾晶须（PTW）填充蓖麻油基聚氨酯（PU）/环氧树脂（EP）互穿聚合物网络（IPN）复合材料。从组成上系统地研究了IPN复合材料的阻尼性能、热稳定性和拉伸强度。结果表明，PTW的加入能显著提高PU/EP IPN的阻尼性能，并能提高PU/EP IPN的热分解温度。拉伸试验表明，PTW的加入提高了IPN复合材料的拉伸强度。PTW填充IPN复合材料有望用作结构阻尼材料。(C)2010爱思唯尔有限公司保留所有权利。
A series of potassium titanate whiskers (PTW) filled castor oil-based polyurethane (PU)/epoxy resin (EP) interpenetrating polymer network (IPN) composites were prepared. The damping properties, thermal stability as well as tensile strength of the IPN composites were studied systematically in terms of composition. Results revealed that the addition of PTW can significantly improve the damping properties of pure PU/EP IPN and can improve the thermal decomposition temperature. Tensile tests showed that the tensile strength of the IPN composites was improved after the incorporation of PTW. It is expected that the PTW filled IPN composites may be used as structural damping materials. (C) 2010 Elsevier Ltd. All rights reserved.
