| Abstract: |
| 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. |
