| Abstract: | It is shown that the adsorption of Sn(II) compounds proceeds by chemical mechanism when ion exchange with carboxyl groups is realized on the polyimide film from the acid and not aged SnCl2 solutions and by physical mechanism which includes colloidal particles sticking on the alkali silica glass from the acid and alkaline, freshly prepared and aged solutions. The adsorbed nanoparticles fulfill the function of the growth centers. It is determined that only chemical adsorption can provide the formation of island-type uniform monolayer film, which consists of the particles 5-10 nm in sizes at a quantity of 300-600 µm−2 and covers the dominating part of the substrates. |
