Abstract
The present disclosure provides a freezing transfer method for porous carbon electrodes based on subzero temperature and applications in sensors, the method including: forming porous carbon electrodes to be transferred on a substrate, introducing a hydrogel material between the porous carbon electrodes to be transferred and a flexible/elastomeric material, expanding the hydrogel material to form a structural coupling with porous carbon, removing the substrate to realize peeling, and completing the transfer of the porous carbon electrodes. According to the present disclosure, fast and complete peeling of the porous carbon electrodes can be realized, a thinner flexible-elastomeric substrate is required, and a composite electrode formed has superior electroconductive stretchability, which helps to realize manufacturing of conformal flexible electronics such as ultrathin flexible or stretchable sensors.
