摘要:
The present discovery shows how to make a self-crosslinking SMP. Shape Memory Polymer (SMP) can be formulated as a castable coating. This process allows the polymer to dissolve in solvent, and as the solvent evaporates the polymers self-crosslink at room temperature in air, creating a copolymer coating wherein the copolymer coating is an SMP. This technology has coating applications where shape memory would be an asset: from shape memory textile and fabric to self-healing coatings for vehicles and morphing skins for aircraft.
