Abstrakt:	Organic/inorganic hybrid materials were formed using the sol-gel process, in which SiO2/fluoroalkyl- trialkoxysilane (FAS)/2-hydroxyethyl methacrylate (2-HEMA)/trimethylolpropane triacrylate (TMPTA) and SiO2/3-(trimethoxysilyl)propyl methacrylate (MSMA)/ 2-HEMA/TMPTA thin films were formed on a glass substrate using dip coating. Experimental results revealed that FAS and MSMA improved the pencil hardness of SiO2/2-HEMA/TMPTA thin films without affecting their optical properties. FAS strengthened the hydrophobic and hydrophilic characteristics of SiO2/2-HEMA/TMPTA thin films more than did MSMA. However, an excess of FAS and an increase in withdrawal rates deteriorates the gloss, because both increased the SiO2 content, reducing the reflectivity. [ABSTRACT FROM AUTHOR]
