DISSOLUBLE PDMS-MODIFIED p(HEMA-MAA) AMPHIPHILIC COPOLYMER AND METHOD FOR FABRICATING THE SAME

A method for fabricating a dissoluble poly(dimethylsiloxane)-modified poly(2-hydroxyethyl methacrylate-methacrylic acid) amphiphilic copolymer, comprising steps:

• dissolving 2-hydroxyethyl methacrylate (HEMA) and methacrylic acid (MAA) in deionized water to form a first solution, adding a photo initiator to said first solution to form a second solution, agitating said second solution uniformly, and illuminating said second solution with ultraviolet ray to polymerized compounds in said second solution to form a third solution, which is a white-colored solution containing a copolymer;
• adding an activating reagent and an alcohol solvent to said third solution containing said copolymer to form a fourth solution, and agitating said fourth solution uniformly to form a mixture solution;
• slowly dripping a dimethylsiloxane (DMS) solution to said mixture solution to form a fifth solution, adding a catalyst to said fifth solution to form a sixth solution, and agitating said sixth solution uniformly to form a solution of a poly(dimethylsiloxane)(PDMS)-modified poly(HEMA-MAA) amphiphilic copolymer.
