Aug 01, 2022 · In order to describe the deformation properties of shape memory polymers, viscoelastic model is used. In this paper, the long-term relaxation modulus is 27.7 MPa, Poisson's ratio is 0.4, and the thermal expansion coefficient is11.6 × 10 −5 K −1. T g is 54.85 °C,C 1 is 15.6, andC 2 is 32.6 .. The folding and deployable process of the model is divided into four stages: …
