Effect of silane modified nano ZnO on UV degradation of Polyurethane Coatings
Progress in Organic Coatings, 2015Co-Authors: To Thi Xuan Hang, Nguyen Thuy Duong, Ngo Thanh Dung, Trinh Anh Truc, Bui Van Truoc, Thai Hoang, Dinh Thi Mai Thanh, Marie-georges OlivierAbstract:Nanosized ZnO modified by 2-aminoethyl-3-aminopropyltrimethoxysilane (APS) was prepared using theprecipitation method. Modified nano ZnO by silane (ZnO-APS) was characterized by XRD, SEM, TEM and UV-vis measurements. The degradation of the Polyurethane Coating, the Polyurethane Coatings containing 0.1 wt% nano ZnO and the Polyurethane Coatings containing nano ZnO-APS at two concentrations (0.1 and 0.5 wt%) during QUV test was evaluated by gloss measurement and electrochemical impedance spec-troscopy. The Coating surface after QUV test was observed with SEM. The results show that nano ZnO-APS has spherical structure with particle size around 10-15 nm. Nano ZnO improved the UV resistance of the PU Coating and surface treatment by APS enhanced the effect of nano ZnO. The presence of nano ZnO-APS at 0.1 wt% concentration significantly improved the UV resistance of Polyurethane Coating.

MODIFICATION OF GRAPHENE OXIDE BY CURCUMIN AND APPLICATION IN Polyurethane Coating
'Publishing House for Science and Technology Vietnam Academy of Science and Technology', 2020Co-Authors: To Thi Xuan Hang, Nguyen Thuy Duong, Boi An Tran, Phan, Thanh Thao, Vu, Ke Oanh, Nguyen, Anh Son, Nguyen, Tuan AnhAbstract:Curcumin modified graphene oxide (GO-CR) was prepared using adsorption method and Polyurethane (PU) Coating containing 0.3 wt% GO-CR was prepared on carbon steel. Synthesized GO-CR was characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and zeta potential measurement. Corrosion protection property of Polyurethane Coating containing GO-CR was evaluated and compared with blank Polyurethane Coating and Coating containing GO by electrochemical impedance spectroscopy. The results showed that GO-CR has layer structure like GO with lower crystallinity. In GO-CR structure curcumin was attached on GO surface. The presence of curcumin on GO-CR surface provided corrosion inhibition action for PU Coating and also improved the dispersion of GO in PU Coating
