Recently, development of functionalized hybrid hard coating materials has beenperformed for the application of touchscreen display panel.In this study, tridecafluoro-n-octylsilane (TFS)as a flourinated alkoxy silane wasusedto obtain hybrid coating films with anti-pollution surface property.The hydrophobic and oleophobic property could be derived through chemicalfixation of flourine alkyl group onto the surface of silica particlesduring sol-gel process.Thermally curable melamine system consisting of Hexamethoxy melamine (HMM) and Hexamethoxymethyl melamine (HMMM) was employedas an organic component in the hybrid coating materials. Surface property and energy of the coated films were evaluated in terms of contact angle for water, ethylene glycol, and n-hexadecane. In addition, the influence of TFS and silica content on the morphology, abrasive resistance, and optical transmittanceof the coated filmwas investigated. Conclusively, hybrid coating films with improved anti-pollutionpropertycould be produced through incorporation of a quite small amount of TFS, which may not result inreduction in surface hardness. |
