Abstract
AbstractRecycled polyvinyl butyral film (RPVB) is reactive blending with different dosages of styrene‐maleic anhydride copolymer (SMA) in a torque rheometer. The shape memory properties of the RPVB/SMA blends are studied. The cross‐linked reaction between RPVB and SMA is the main factor affecting the shape memory properties of the binary blends. When the RPVB and SMA blending ratios are 3:1 and 4:1, both blends exhibit superior shape memory properties (the shape fixation ratios are above 96% at room temperature, and the shape recovery ratios are over 99% at 80°C). Furthermore, the RPVB/SMA/NRGO composites are prepared by adding the NH2‐functionalized reduced graphene oxide (NRGO) with an excellent thermal stability. The introduction of NRGO not only improves the tensile properties of the composites, but also endows them with an excellent light‐induced shape memory function.
