Enhanced skin adhesive property of α-cyclodextrin/nonanyl group-modified poly(vinyl alcohol) inclusion complex film

For skin contact medical devices, realizing a strong with is essential to precisely detect human biological information and enable human-machine interaction. In this study, we aimed fabricate characterize an inclusion complex film (ICF) for adhesion using α-cyclodextrin (α-CD) nonanyl group-modified PVA (C9-PVA) under wet conditions. Based on the water insolubility of C9-PVA ability α-CD alkyl groups, α-CD/C9-PVA ICF was prepared. Among prepared ICFs, α-CD/2.5C9-PVA (w/w = 0.5) showed highest bonding strength T-peeling porcine skin. Furthermore, had better vapor transmission rate than that commercial tapes. addition, ion permeability test revealed exhibited excellent Na Cl permeability. These results demonstrated multi-functional can be promising adhesive devices.
