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： A method for preparing an acrylate laminating adhesive by soap-free emulsion polymerization, and an acrylate laminating adhesive prepared by soap-free emulsion polymerization. In the method, an acrylate block oligomer with emulsifiability is synthesized by using a RAFT active radical polymerization process, and an acrylate monomer is emulsified by using the acrylate block oligomer for a semi-continuous emulsion polymerization, which overcomes a defect that traditional small molecule emulsifiers tend to migrate to a surface of an adhesive film to form a weak interface layer, resulting in a decreased bonding strength, a poor water resistance and the like. Further, in the disclosure, the use of n-pentanol as a chain transfer agent could not only reduce the molecular weight of polymer, improving fluidity and laminating uniformity of the adhesive, but also reduce the surface tension of the emulsion, improving coating wettability and levelling properties of the acrylate laminating adhesive.
