- Abstract
Polycaprolactone (PCL) networks with disulfide bonds are synthesized through a thiol‐ene "click" reaction. The PCL networks have various functional properties, including self‐healing, shape memory, reprocessability, and degradability. Pronouncedly, a healing efficiency of 92% on the yield strength of the PCL network is obtained after heating for 1 h at 60 °C. Meanwhile, the PCL networks show shape memory property with fixing ratio (Rf) and recovery ratio (Rr) at 98% and 95%, respectively. The PCL network still retains good mechanical properties after reprocessing cycles and can be fast‐decomposed through a thiol‐disulfide exchange reaction. A novel polycaprolactone (PCL) network is conveniently synthesized through a highly efficient thiol‐ene "click" reaction. The optimized PCL network with 105 MPa Young's modulus can achieve a healing efficiency higher than 90% after heating for 1 h at 60 °C. Meanwhile, the optimized PCL network also has shape memory ability, reprocessability, and degradability.
