PDMS is the most widely used silicon-based organic polymer, as its versatility and properties lead to many … See more The chemical formula of PDMS is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [Si(CH3)2O] units. Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: See more PDMS is hydrophobic. Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air plasma and argon plasma will work for this application. This treatment renders the PDMS surface hydrophilic, … See more According to Ullmann's Encyclopedia, no "marked harmful effects on organisms in the environment" have been noted for siloxanes.
