摘要
采用不同禾本科植物纤维对聚丁二酸丁二醇酯(PBS)进行改性,利用热压成型工艺得到植物纤维/PBS复合材料。研究了植物纤维颗粒大小及含量对复合材料力学性能的影响,通过力学性能测试、热重分析(TGA)、X射线衍射(XRD)、接触角测量等方法比较了不同植物纤维/PBS复合材料性能的差异。研究结果表明,120mesh植物纤维添加量为5%时,复合材料性能最优;竹纤维复合材料较稻草、小麦纤维复合材料具有更优的力学性能、热稳定性、疏水性;禾本科植物纤维的纤维素、综纤维素结晶度越高,植物纤维复合材料性能越好。
poly ＇（butylene succinate） （PBS） was modified by different gramineae fiber, and gramineae fiber/PBS composites were prepared by hot-pressing technology. The effects of plant fiber particle size and content to the mechanical properties of composites were studied, the performance differences of gramineae fiber/PBS were analyzed hy mechanical test, TGA, XRD and contact angle measurement. The results show that when the content of 120 mesh plant fiber is 5%, the performance of composite is the best, bamboo fiber/PBS composites has the better mechanical, thermal stability, hydrophobicity properties compared with rice straw/PBS composites, wheat fiber/PBS composites. When the crystallinity of the gramineae plant fiber is higher, the performance of the composites is better.
