| 摘 要： | Shape memory polyurethane(SMPU)is a typical temperature-sensitive functional polymer having an excellent shape memory behavior1,which has been extensively studied since19882,10.B.K.Kim et al.3reported the effect of hard segment contents(HSC)and soft segment length(SSL)of SMPU on its modulus,hardness and recovery strain.They attributed these effects to its micro-phase separation of its soft segment and hard segment as well as its soft segment crystallization.F.K.Li et al.4found that high…

| Abstract: | A novel method of controlling the shape memory properties of shape memory polyurethane (SMPU) by addition of micro-phase separation promoters including 1-octadecanol (ODO) and liquid paraffin (LP) is reported. The results indicate that the strain recovery temperature and the strain modulus rate (Eg/Er) were increased significantly with addition of small amount of micro-phase separation promoters. Thus it can increase the shape memory fixity rate and other shape memory behaviors of SMPU. |
