1. A sol-gel method for preparation of a self-cleaning coating solution, the method comprising the steps of:
mixing an aluminium compound with a solution of an ethanol compound to form a solution;
subjecting the formed solution to a first magnetic stirring, wherein after the first magnetic stirring a first transparent solution is formed;
adding 302 μL of stabilizing agent to the first transparent solution of the aluminium compound and the ethanol compound, wherein the stabilizing agent comprises mono-ethanolamine that decreases a rate of hydrolysis of the aluminium compound, wherein subsequent to adding the stabilizing agent a translucent solution is formed, and wherein the stabilizing agent controls reaction kinetics and forms mono-dispersed alumina nanoparticles for providing a thin film coating; and
subjecting the formed translucent solution to a second magnetic stirring for forming a homogeneous second transparent solution, wherein the second transparent solution formed is a coating solution.
