摘　　要：聚3-羟基丁酸酯4-羟基丁酸酯（P34HB）是聚羟基脂肪酸酯（PHA）的最新一代产品，为提高其物理机械性能、降低成本，本文对P34HB进行了天然竹纤维（BF）增强，并研究了复合材料结构、物理机械性能和降解性能。结果表明，改性后的BF的添加量为10％（wt％）时，所制得的P34HB／BF复合材料的力学性能达到最佳，拉伸强度和弯曲强度分别提高了56．8％和46．2％，复合材料的结晶温度和热稳定性也得到了一定程度的提高，且复合材料的碱降解能力较纯P34HB得到了很大的改善。In this paper, a new kind hydroxybutrate（P34HB）was reinforced with of biomaterial, poly-3-hydroxybutyratemodified bamboo fiber（BF）to improve the properties and reduce the cost. The results showed that the optimum mechanical properties reached when the BF loading was 10 phr, the tensile strength and bending strength was increased by 56.8% and 46.2% compared with that of pure P34HB, respectively.The crystallization temperature and thermal stability of P34HB/BF composite were enhanced,as well as the degradability of the in alkali solution.
