11 Claims

1. A method of synthesizing a clay-polyacrylate composite comprising the steps of:

a) mixing an aqueous solution comprising clay with at least one organosilane coupling agent comprising an acrylate moiety to form a silanized-clay suspension;

b) contacting the silanized-clay suspension with a first acrylate monomer and a second acrylate monomer in an inert environment, wherein the first acrylate monomer and the second acrylate monomer have different solubility; and

c) adding a polymerization initiator to the silanized-clay suspension before or during step (b) in the inert environment to form the clay-polyacrylate composite comprising the first and second acrylate monomer, wherein the first acrylate monomer is a hydrophilic acrylate monomer comprising a hydroxyl (—OH) group and the second acrylate monomer is a hydrophobic acrylate monomer which repels water.
