Shape memory fixity
Webb28 feb. 2024 · Shape memory polymer (SMP) is a kind of smart material, which has the advantages of large strain and low density. It has broad application prospects in space … WebbThe result is a shape memory PB-PODA copolymer that can be fabricated by melt processing and programmed without cooling below ambient temperature. It is found that good shape memory (i.e., high shape fixity and recovery) is obtained at a low PB weight fraction where a percolating PODA crystal network is formed at room temperature.
