Development of biobased dynamic thiol–acrylate photopolymers: 3D-printed self-healing and shape memory materials

Abstract

), mechanical performance, and network adaptability. The findings from stress relaxation experiments indicate that the printed material is capable of dissipating 63% of its initial stresses within 3.6 minutes at a temperature of 200 °C, thereby facilitating self-healing and shape reformation. The materials showed promising healing, shape memory, degradability, and reprocessing capabilities, highlighting its potential for use in soft active devices and soft robotics application.
