The invention discloses ionic conductive
polyurethane with
high adhesion and self-repairability and a preparation method thereof, and belongs to the technical field of high-performance conductive binding materials, the method comprises the following steps: mixing 1-ethylimidazole and 3-chloro-1, 2-
propylene glycol, condensing and refluxing, sequentially extracting in trichloromethane and
acetone solutions, and
drying in vacuum to obtain the ionic conductive
polyurethane with
high adhesion and self-repairability. The dihydroxy imidazolyl
ionic liquid is prepared; the preparation method comprises the following steps: adding a dihydroxy imidazolyl
ionic liquid solution into a
polyurethane prepolymer, stirring for reaction, adding a polyhydroxy MXene-OH dispersion liquid subjected to
etching treatment and a 1, 3, 5-tri (6-isocyanatohexyl)-1, 3, 5-
triazine-2, 4, 6-trione cross-linking agent, carrying out chain extension cross-linking reaction, adding 1-ethyl-3-methylimidazoline bis (trifluoromethylsulfonyl)
imine, and carrying out reaction, so as to obtain a polyurethane
prepolymer; and carrying out mold pouring and
drying treatment to obtain the ionic conductive polyurethane with
high adhesion and self-repairing property. The covalent cross-linked network endows the material with good
toughness, and the bi-cross-linked structure can also effectively block
permeation of water molecules, so that the problem of poor
water resistance of the traditional polyurethane material is solved.
