UV-induced Radical Graft Polymerization of Water-soluble Monomers from Glass Surface

Abstract: Fixed to the surface of the glass with a layer of γ-propyl triethoxysilane (KH-550) , the amino of the KH-550 and the benzophenone (BP) derivative LQBSB can form photoinduced redox initiate system to photoinduce water-soluble monomer on the glass surface radical polymerization, so as to achieve the purpose of  modification of the glass surface. The polymerization of acrylates, acrylamides and other water-soluble monomer was initiated on the glass surface.The glass surface was characterized by attenuated total reflection Fourier transform infrared spectroscopy (ATR - FTIR) and contact angle tester to prove the polymer was successfully grafted on it. Polymerization on the glass surface accomplished in a shorter time, 6 minutes was enough. To study the DMAAm in detail as a model.When the ratio of raw materials was m(LQBSB):m(DMAAm):m(H2O)=5:100:1000 and reaction time was 6 minutes, the graft ratio and the grafted amount per unit area of the samples reached 2.96 ‰ and 7.75 mg/cm2, the surface has also undergone a significant change. Among these monomers , the graft effect of N, N-dimethylacrylamide (DMAAm) was much more obvious. The effect of the amount of initiator and the reaction time on the grafting rate was researched. And the test showed good adhesion properties between acrylic resin and the glass surface grafted with DMAAm.
