%X 采用熔融共缩聚反应法合成聚（丙三醇-癸二酸-柠檬酸）酯（PGSC）弹性体，再采用半原位聚合和研磨分散的方法制备多壁碳纳米管(MWCNT)/PGSC复合材料，并对复合材料的性能进行研究。结果表明，MWCNT对PGSC的玻璃化温度影响不大；随着MWCNT用量的增大，MWCNT/PGSC复合材料的弹性模量和拉伸强度总体增大，溶胀度和吸水率逐渐减小；当MWCNT用量达到或超过1份时，与PGSC相比，MWCNT/PGSC复合材料的弹性模量和拉伸强度较大，降解速率较小。;A poly(glycerol-sebacate-citrate)(PGSC) elastomer was synthesized by melting copolycondensation，then a MWCNT/PGSC composite was prepared by semi-in-situ polymerization and grinding dispersion method，and the properties of composite were investigated.The results showed that the MWCNT had little effect on the glass transition temperature of PGSC；as the addition level of MWCNT increased，the elastic modulus and tensile strength of MWCNT/PGSC composite increased，the swelling degree and water absorption decreased；when the addition level of MWCNT reached or exceeded 1 phr，the elastic modulus and tensile strength of MWCNT/PGSC composite were higher than those of PGSC，and the degradation rate was lower
