The invention discloses a preparation method of a low temperature resistant, fatigue resistant and oil swelling resistant organic hydrogel pressure sensor, which comprises the steps of firstly forming a silver nanowire-polymer hydrogel substrate with a porous structure by adopting oriented freezing, then modifying the silver nanowire wall of the hydrogel substrate by using a photoinitiator 907, and finally introducing an oily precursor solution for ultraviolet light polymerization. Meanwhile, due to the synergistic effect of the two hydrophilic and oily interpenetrating networks, the organic hydrogel prepared by the invention has excellent low temperature resistance, low temperature resistance and oil swelling resistance. |
