Bonding composite gel easy to disassemble

The invention discloses bonding composite gel easy to disassemble and belongs to the technical field of bonding materials easy to disassemble. The composite gel comprises a gel A and a gel B. A preparation method of the gel A comprises the following steps: taking acrylamide and acrylamide-beta-cyclodextrin as raw materials, taking N, N '-methylene bisacrylamide as a cross-linking agent, and carrying out free radical copolymerization reaction to obtain beta-cyclodextrin-polyacrylamide gel; a preparation method of the gel B comprises the following steps: carrying out oxidative cracking on bacterial cellulose by using sodium periodate, carrying out amination modification on the bacterial cellulose by using polyethylamine, and carrying out amidation reaction on the modified bacterial cellulose and 1-adamantanecarboxylic acid to obtain the adamantyl-bacterial cellulose gel. The gel A and the gel B are bonded in deionized water to form composite gel, the composite gel is detached in ethyl alcohol to obtain the gel
