Thermomechanical Deformation Analysis of Shape Memory Polymers Using Viscoelasticity

Some segmented polyurethane polymers are known to have shape memory function, i.e., when a certain temperature is given to them, they deform into a memorized shape from any temporary ones. In this study, shape memory polymers were characterized using DMTA to investigate their viscoelastic behavior,...

Summary:Some segmented polyurethane polymers are known to have shape memory function, i.e., when a certain temperature is given to them, they deform into a memorized shape from any temporary ones. In this study, shape memory polymers were characterized using DMTA to investigate their viscoelastic behavior, in particular focusing on the thermomechanical deformation. Then, the linear viscoelastic theory was applied to model their thermomechanical behavior in the small deformation regime and its validity was discussed focusing on the fixity and recovery property of the shape memory polymer.
