Abstract:
      Ethylene-propylene-diene monomer rubber（EPDM）/SiO2 composites were prepared by mechanical blending，and EPDM based artificial muscle materials were prepared by mechanical training process，and their properties were studied.The results showed that，when the strain of mechanical training increased from 50% to 120%，the elastic modulus of EPDM based artificial muscle material of EPDM composites with 40 phr of SiO2 and 12 phr zinc methacrylate（recorded as S40Z12） increased from 2.8 MPa to 35.8 MPa，12 times of the increase.The Kraus curve slope of EPDM based artificial muscle material after mechanical training remained negative and the absolute value was larger，indicating that the interface interaction between EPDM matrix and SiO2 particles was enhanced.Under fixed stress mode，The reversible driving strain of EPDM based artificial muscle material of S40Z12@350%（with 350% of mechanical training strain） reached 47%.Under the thermal stimulation response，EPDM based artificial muscle material could drive the load object to achieve multiple reversible switching of rising and falling repetitive actions，with a driving load mass exceeding its own mass by 126 00 times and a driving strain greater than 35%.
