In Figures , the experiment was conducted to compare and contrast Si-OR bonds, with/without the presence of a catalysis. The theory behind the time manipulation on the sol-gel process, states, if the acid acids can form a strong interconnected network, with an increase rate, then, the heating treatment performed on should take less time, since the bonds are stronger, performing a heating treatment should take less than four hours and form the sol-gel bonds. Based on the graphs below, one can confirm, the four hours of heating, is an essential step and must be perform for the strong Si-OR bonds.
