(57) [Summary] [Problem] An article storage sheet that reversibly absorbs and releases moisture in the air at a specific temperature, suppresses a large change in humidity, and provides an environment suitable for storage of articles and the like. Get. SOLUTION: This article-preserving sheet contains a polymer gel exhibiting a property of reversibly absorbing and releasing contained water when a specific temperature is reached. The monomer constituting the polymer gel is an organic compound exhibiting the property that the solubility in water is reversibly different at a specific temperature, and the monomers are N-ethylacrylamide, N-cyclopropylacrylamide, N-isopropylacrylamide. , N-methyl-N'-ethylacrylamide, N, N'-diethylacrylamide, N-methyl-N-isopropylacrylamide, N-methyl- It is a substance represented by Nn-propylacrylamide and the like. |
