Problems solved by technology

Although the above research work has achieved certain results, there are still shortcomings, mainly reflected in: the preparation process of photothermal conversion agents such as gold nanoparticles is complicated, which increases the processing cost of smart materials; changing the cross-linking method, although improving the material Mechanical strength, but correspondingly reduces the deformation ability of smart materials; using active materials and passive materials, although deformation driven by near-infrared light can be realized, the interlayer bonding strength is poor, which weakens the service life of smart materials
