Abstract
The disclosure provides a system of thermoset shape memory poly(urea-urethane) with permanent reshaping property and its application. The breakthrough of the present invention is that the reshaping temperature can be tuned in a wide range by incorporation of urea bonds into the polymer network. The permanent shape for shape memory poly(urea-urethane) can be repeatedly and cumulatively reshaped at certain temperature, largely facilitating the fabrication of complex structures.
