The invention discloses a method for constructing anisotropic conductive hydrogel based on bidirectional freezing. First, sodium alginate and silver nanowires are mixed uniformly, and then long-range ordered silver nanowires with layered structure are formed by bidirectional freezing. Wire-sodium alginate aerogel substrate, after adding monomers and cross-linking agents to the aerogel to construct a hydrogel with a layered structure, due to the existence of silver nanowires in the aerogel wall and the subsequent injection of After the hydrogel is loaded, the structure of the initial aerogel is not destroyed, so the prepared hydrogel has good electrical conductivity, and because the hydrogel has a long-range ordered layered structure, it is parallel to the layered direction. and the stress perpendicular to the layered direction are also different, thereby exhibiting anisotropic properties. |
