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. |
