<P>PROBLEM TO BE SOLVED: To provide a high-diffusion-coefficient material such as wet gel. <P>SOLUTION: The material is a material comprising (i) a first polyrotaxane, (ii) at least either of the following substances (a) and (b): (a) a first polymer except the first polyrotaxane and (b) a second polyrotaxane, (iii) a solvent, and (iv) a first solute, wherein at least part of the first polyrotaxane (i) and at least part of the substance (ii) are chemically and/or physically crosslinked, and the effective diffusion coefficient D/q<SP>1/3</SP>(wherein D is a diffusion coefficient; and q is the swelling degree of the material) of the first solute in the material is at least 1.1 times larger than the effective diffusion coefficient of a second solute in a comparative sample which is a comparative sample entirely consisting of poly(acrylamide), water, a tris-hydrochloric acid buffer, and the second solute being disodium 3-hydroxy-4-[(2,4,5-trimethylphenyl)azo]-2,7-naphthalenedisulfonate and has a water content of 95%. <P>COPYRIGHT: (C)2008,JPO&INPIT |
