Thermally activated shape memory behavior of copolymers based on ethylene reinforced with silica nanoparticles

In this work, a study on the dual-shape and triple-shape memory response of poly(ethylene-co-methacrylic acid) copolymer, EMAA, and its counterpart neutralized with sodium salt, EMAA-Na has been report. Moreover, both matrices were reinforced with silica nanoparticles in different amount. Morphologi...
