摘要： An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.

摘要： It is an object of the present invention to provide a hydrogel, in which its initial high adhesive force is retained by suppressing the swelling of the gel due to invasion of water from the outside and reducing the loss of a plasticizer.
The hydrogel of the present invention is a hydrogel comprising a polymer matrix, water and a plasticizer, wherein the hydrogel is characterized in that the plasticizer loss ratio is less than 2, the swelling rate is 115% or less when the hydrogel is exposed to the environment of 40° C. and 90% RH for 1 hour, and the initial adhesive force to a Bakelite plate is 100 gf/20 mm or more in the environment of 23° C. and 55% RH. The plasticizer is preferably polyoxyalkylene alkyl ether and/or sugar.
