Abstract
A biomimetic polymer adhesive comprising a poly (gallol-co-styrene) group, its use in dry and wet (e.g., underwater) adhesion, and its method of manufacturing.
Claims9
A method of manufacturing a gallol-containing polymer adhesive, the method comprising the steps:
- (i) mixing a dispersant and a surfactant in the presence of a solvent;
- (ii) mixing a styrene monomer with 3,4,5-trialkoxy styrene monomer;
- (iii) adding an initiator to the mixture of monomers of step (ii);
- (iv) adding the initiator-monomer mixture of step (iii) to the mixture of step (i) to form monomer droplets;
- (v) allowing a polymerization reaction in the monomer droplets under continuous stirring;
- (vi) quenching the polymerization reaction to obtain 3,4,5-trialkoxy styrene-co-styrene;
- and
- (vii) hydrolyzing the 3,4,5-trialkoxy styrene-co-styrene to obtain the gallol-containing polymer.
