By using organic amine as the soft template, TiO2 nanostructured thin films have been deposited on the surface of short glass fibers (SGFs) by biomimetic synthesis technology at low temperature (85°C). The properties of composite particles, including surface morphology, the phase composition of the coating layer and microstructure were characterized by SEM, XRD, XPS and Raman. The results show that the functional layers containing NH2 and OH groups can be formed through a kind of organic amine, which can induce the bio-mineralization of nano-TiO2 on the SGFs surfaces. The XRD shows that TiO2 thin films uniformly coated on SGFs surfaces were mainly anatase. The surface roughness of SGFs was remarkably increased after coating. Compared with uncoated SGFs as filler, the abrasive loss of composite coatings decreased to 47 percent of that coatings filled with uncoated SGFs, when the composite fiber powders were filled in wear-resistant coatings based on the silicone modified epoxy resins. Therefore, anti-wear property of coatings was notably enhanced. |
