Abstract: In this work,we grafted polyvinyl alcohol( PVA) with a functionality of adhesive structure,3,4-dihydroxybenzaldehyde,to obtain a mussel-inspired modified PVA( m-PVA). Firstly,m-PVA was synthesized with PVA and 3,4-dihydroxybenzaldehyde via acetalization. The m-PVA was characterized by UV-spectra,FT-IR and H1 NMR,which confirmed the catechol was grafted in the polymer. And the grafting ratio is about 10%. In addition,the thermal stability of m-PVA was also measured by TG analysis method. For mimic of mussel adhesive protein gel,UV-spectra were used to study the formation of m-PVA adhesive gel,which was obtained by coordinating with Fe3 +with different p H. UV-spectra were also used to investigate the formation of m-PVA adhesive gel,which formed by oxidation of Na IO4 that can oxidize the catechol to form quinone. Through our primary work,adhesive gel was synthesized successively,which mimics mussel adhesive protein gel to some extent.
