Abstract

The invention provides high-transparency polyvinyl alcohol hydrogel as well as a preparation method and application thereof. According to the high-transparency polyvinyl alcohol hydrogel, polyvinyl alcohol and inorganic salt are used as raw materials, water is used as a solvent, the concentration of the polyvinyl alcohol is 3-30 wt%, and the concentration of the inorganic salt is 0.5-29.9 wt%. The method disclosed by the invention is green and environment-friendly, and the prepared polyvinyl alcohol hydrogel has high transparency, adhesion and ultralow-temperature freezing resistance, and has elasticity, ductility, ionic conductivity and moisture retention, so that the problems of non-transparency, no adhesion, no freezing resistance and the like of the polyvinyl alcohol hydrogel during application are solved, and the prepared polyvinyl alcohol hydrogel can be applied to the fields of medicines, materials and sensors.
