A mixture of the sugar solution and polyacrylic acid was prepared by mixing 3.7 % (w/w) of PAA in the sugar solution until PAA was dissolved in it homogeneously. The composite coating was made by mixing 36% (w/w) of the above sol-gel solution with, 7 % (w/w) of glycerol, 1 % (w/w) of superwetting agent, and 56 % (w/w) of PDMS & its corresponding quantity of its cross linker (10:1.2). While most of the experiments were performed with polyacrylic acid, we have also used polyvinyl alcohol occasionally. With the latter, 7% of an aqueous solution of PVA was added to the sugar solution and was heated with continuously stirring at 60C° till a clear solution was formed. 36% of this solution was then blended with the other components to prepare the base of the composite coating.
