Polysiloxane dressings offerthe advantage of low irritation during removal; however, their practicalapplication remains restricted by poor adhesive performance and physiologicalinertness. Inspired by mussel foot proteins, protocatechuic aldehydewas grafted via Schiff base reaction onto the pendant chains of anaminopropyltriethoxysilane (APTES)/vinyltriethoxysilane (VTES)/polyethyleneglycol (PEG) copolymer synthesized by transesterification, yieldingPAP enriched with catechol pendant groups and vinyl moieties. ThePAP was subsequently incorporated into a polysiloxane gel matrix viahydrosilylation to fabricate the PAP-gel dressing. The incorporationof catechol groups enhanced interfacial adhesion and enabled sustainedadhesive performance under moderately moist conditions. The gel conformedwell to wound geometry, ensuring intimate contact with damaged skin,thereby increasing the wound–dressing contact area for improvedadhesion stability while facilitating interaction between the woundbed and catechol groups for therapeutic benefit.
