Abstract Poly(N-isopropylacrylamide)-based stimuli-responsive hydrogel actuators have made significant progress. By introducing responsive modules such as photothermal nanoparticles, the can respond to environmental changes and construct anisotropic structures, allowing quickly bend realize complex shape deformation. However, there remains a need enhance mechanical properties of these hydrogels accommodate multiple deformation actions different application scenarios, compatibility between nanoparticles improve comprehensive performance materials are still issues that be solved. In this study, we modified two-dimensional MXene nanosheets with polydopamine (PDA) obtain P-MXene, which served agent stably dispersed within system. We copolymerized thermosensitive N-isopropylacrylamide (NIPAm) 2-(dimethylamino)ethyl methacrylate (DMAEMA) in situ used direct current electric field induce concentration gradient distribution P-MXene hydrogel, resulting preparation good stretchability conductivity. The structure was characterized using scanning electron microscopy Fourier transform infrared spectra. swelling properties, conductivity were studied. actuation behavior P(NIPAm-DMAEMA)/P-MXene under thickness intensity investigated. Additionally, sensitivity stability conductive tested functions monitoring human health information transmission realized. It integrated rapid photo responsiveness self-sensing capabilities monitor process through real-time relative resistance during actuations. This work is expected expand soft provide new insights into design generation robots.
