Na2S04 is then extracted by water and the composite films are dried in absolute alcohol. Polyacrylic acid can also be extracted by multiple washing in water. Decrease in temperature leads to the decrease of particle sizes down to 10 nm. A number of non-soluble sulfides such as CuS, ZnS, CdS were synthesized in polyvinyl alcohol matrix by means of this method, which can also be applied to oxide formation [2]. The particle size in that case is determined by tte deformation of polyvinyl alcohol matrix and, in first approximation, does not depend on filler concentration.
