A dry double-sided tape post-treated with tannic acid for long-term adhesion in a wet environment

studies demonstrated that DST-TA had significantly higher swelling resistance and tensile strength than DST. The introduced catecholyl group could reduce over-swelling of the DST, and improve short-term and long-term adhesion in a wet environment. We also demonstrated that the DST-TA had good hemocompatibility, biodegradability, and no cytotoxicity, offering a potential option for long-term medical adhesive in a wet environment.
