Summary:Light-activated shape-memory materials can return to the originally printed or manufactured shape in temperatures higher than their glass transition temperatures. This effect is widely applicable in the field of biomedicine, biology and others. In this research we are focusing on new materials for light-activated 4D printing—the focus is placed on biocompatible CuS nanoparticle /polyurethane composite for light conversion to heat that can be used as a filament for 3D printing. The synthesis of the composite and nanoparticles, as well as the physical properties of the material are described, and the shape-memory effect is tested for different concentrations of the nanoparticle filler. The best results were found to be for 0.5% CuS/PU composite that reached the unfolding time of 63 s under Xe lamp irradiation.
