Paper Abstract

In this paper, the high temperature polyimide-based shape memory polymers were exposed to simulated vacuum thermal cycling environments from −170 °C to +170 °C up to 600 hours for an accelerated irradiation. The effects of vacuum thermal cycling on optical transmittance, stretchable shape memory effects, thermomechanical and thermal properties were evaluated. Even if they experienced 600 hours of vacuum thermal cycling irradiation, the glass transition temperatures (Tg), optical transmittance, thermal stability, and the shape memory effects had no significant changes. The results are quite instructive in selecting and evaluating material for aerospace structures. polyimide-based shape memory polymers also shows great potential application in large-area space flexible electronics.
