Synthesis of Poly(2-Hydroxyethyl Methacrylate)-based Hybrid Nanoparticles via Visible-Light-Initiated Radical Polymerization

Abstract

We report a new, unique process for the design of poly(2‐hydroxyethyl methacrylate) (PHEMA)‐based hybrid materials, which involves the coating of PHEMA on TiO2 and TiO2 /Ag nanoparticle surface under visible light. New hybrid materials initiated under different conditions were prepared under visible light, which could be used for the theoretical design of nanohybrid materials. The hybrid materials thus prepared were characterized by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The experimental results confirmed the successful synthesis of TiO2–PHEMA hybrid materials. Compared to other methods, the method reported here involving the direct combination of PHEMA on the TiO2 surface was simply catalyzed by visible light without the addition of initiators.

“…The great weight loss between 150°C and 260°C was provided by the decomposition of BAC groups . The second weight loss between 260°C and 370°C was due to the degradation of PHEMA chains in the network . Moreover, the large weight loss can be ascribed to the decomposition of the PDMAEMAQ chains and CDs at about 360°C to 440°C .…”

“…23 The second weight loss between 260°C and 370°C was due to the degradation of PHEMA chains in the network. 24 Moreover, the large weight loss can be ascribed to the decomposition of the PDMAEMAQ chains and CDs at about 360°C to 440°C. 25 As shown in Figure 2C, the UV-vis absorption spectra of the CDs and CDs@NGs were measured and found that the absorption wavelength of the CDs@NGs has no significant change in contrast to free CDs.…”
