Abstract:
1. A method of manufacturing a selective infiltration thin film of a specific, pre-determined diameter D (in mm) of the bacteriostatic circle at a constant temperature 37° C., comprising the steps of (a) mixing Polyethyleneimine (PEI) and Polyvinyl Alcohol (PVA) with a casting method for a polymer thin film; (b) setting a value of r ranging between 0 and 1, and rεR, or real numbers; (c) Obtaining a value of M in Pearson's product-moment formula, M=r·D, and adding an amount M of an inorganic metal oxide, namely, Polyoxometalate (POM) into the polymer thin film; (d) forming the selective infiltration thin film, wherein the desired diameter D of the bacteriostatic circle of the thin film corresponds to a diameter D′ obtained according to the following steps: after 24 hours of training of the wafer paper spindles in a constant temperature incubator at 37° C., measuring the diameter D′ of the bacteriostatic circle.
