PRESSURE-SENSITIVE HYDROGEL AND USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive hydrogel.SOLUTION: A pressure-sensitive hydrogel composition includes a liquid solvent, a polymer, and an acid gas. When the acid gas is dissolved in the solvent and the polymer is dissolved in the solvent, the composition is present as a first liquid phase. When the acid gas is not dissolved in the solvent and the polymer is precipitated from the solvent, the composition is present as a second gel phase. The solvent may include at least one of water and a buffer solution.
