Abstract
Traditional adhesives such as cyanoacrylate glue are mostly solvent based. They are facing the problem of insufficient adhesion to some substrates, and also the drawback of volatilization and release of small organic molecules in the process of usage. Therefore, a novel adhesive with non-irritating, high adhesive strength and antibacterial properties is highly required. In this study, a full physically crosslinked zwitterionic poly(betaine sulfonate methacrylate) (PSBMA) hydrogel is proposed. The physical crosslinking interactions endow the hydrogel with good self-healing property. Besides, the pure physical crosslinking hydrogel can form PSBMA powder adhesive after lyophilization and return to the hydrogel state after hydration. The mechanical properties of PSBMA adhesive can be modulated via adjusting the solid content and initiator dosage. Following the cure process similar to that of snail mucus or insect exoskeleton does in nature, adhesion of the PSBMA adhesive is improved at least 100 times than its wet state. In addition, the PSBMA adhesive is easy to be removed due to the dissociation of cross-linked structure in salt water environment. Moreover, PSBMA adhesive with antifouling properties can effectively prevent adhesion of proteins and bacteria, which shows potential applications in assembly of medical devices.
