A new type of sol-gel process addition of ethylene glycol has been developed. Sol-gel derived bulk and thin films were prepared from different compositions containing varying concentrations of ethylene glycol from 5% to 15% at constant water (H 2 O)/tetraethyl-orthosilicate (TEOS) ratio. Scanning electronic microscope (SEM) was carried out to monitor the effects of concentration of ethylene glycol on the internal environment of sol-gel materials. Sol-gel thin films, prepared by rotating coating technique were depicted uniform and cracked surface at rotating speed 2,000 r/min (high speed) and 800 r/min (low speed) respectively. It was shown that an antireflective film produced by incorporation of ethylene glycol in the precursor solution is a more effective method to effect the uniformly porous structures of SiO 2 thin film on the glass substrate. The surface of the film on glass substrates is seen to exist in different conditions with different compositions of ethylene glycol. |
