Hydrophobicity which is one of the surface treatment technologies has been required to improve the quality related to a reliability and stability of semiconductors, optical lenses, solar cell, automotive and display materials for corrosion resistance, chemical resistance, anti-fingerprint, etc. In this study, fluorinated siloxane precursors for a low surface energy were synthesized by the sol-gel reaction. And then transparent water-repellent coating layers were fabricated using synthesized fluorine siloxane-modified polysilazane solutions; which were varied depends on composition ratio of fluorine and siloxane of precursor. The layers appeared transparent hydrophobicity and good chemical resistance as measuring above 91% transmittance, below 0.3% haze and above 109˚ water contact angle. Besides, the coating layer on glass was measured as 9H pencil hardness at a load of 1Kg.
