...Wei Xu; Guoqiang Li Traditionally, programming of shape memory polymer (SMP) material requires initial heating above the glass transition temperature (T g ), subsequent cooling below T g and removal of the applied load. Therefore, the shape fixity process is inconvenient for some applications. Most...

... or anomalous diffusion typically occurs when the rates of diffusion and viscoelastic relaxation in a polymer are comparable, and the ambient temperature is below the glass transition temperature T g of the polymer. As a result, it is necessary to take into account the time-dependent response of a polymer...
