Nature-inspired multifunctional membrane adaptively hybridized with PNIPAm and PPy
Plants have specialized functions to resure their survival and reproduction in a great diverse of habitats. Some palnts contain soft materials which equip combinational functions of deformability and electrochemical properties in response to various environmental stimuli. Stimuli-responsive hydrogel with electrochemical property is a good candidate for imitating such special functionalities in nature. They have great potential in a wide range of academic sciences and industrial applications, such as in biosensors, actuators, and biomedical devices. However, their mechanical rigidity, multistep fabrication processing, and low reproducibility reduce applicability. Here, nature-inspired from stimuli-responsive functionalities of vascular plants, a new thermo-responsive multifunctional hybrid membrane (HM) is synthesized by in situ hybridization of conductive poly(pyrrole)(PPy) on a photopolymerized poly(N-isopropylacrylamide)(PNIPAm) matrix. In terms of morphology, the HM can be easily fabricated into various structures by photopolymerization patterning, and it exhibits thermo-responsive deformability. In terms of functionality, it exhibits various electrical and charge responses to thermal stimuli. This simple and efficient fabrication method could be used as a promising platform for fabricating a variety of functional devices.
