Inorganic nanoparticle-dihydric alcohol dispersion liquid as well as preparation method and application thereof

The invention relates to the technical field of material modification, in particular to an inorganic nanoparticle-dihydric alcohol dispersion liquid as well as a preparation method and application thereof, and provides the following scheme: the preparation method comprises the following steps: mixing inorganic nanoparticles and a dihydric alcohol solvent, and carrying out nanometer grinding dispersion to obtain a mixed liquid; uniformly mixing a silane coupling agent and a grafting stabilizer, and adjusting the pH value to be alkaline to obtain a modified solution; continuously adding a grafting stabilizer into the modified liquid, and mixing with the mixed liquid to obtain an inorganic nanoparticle dispersion liquid; and carrying out rotary evaporation to remove the redundant grafting stabilizer to obtain the inorganic nanoparticle-dihydric alcohol dispersion liquid. According to the method, under the condition that the total addition amount of coupling agent types is not changed, the grafting stabilizing li
