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. PDMS is … See more • Amodimethicone Amodimethicone structure and properties See more PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid, similar to honey. However, at short flow times (or low temperatures), it acts like an elastic solid, similar to rubber. Viscoelasticity is a form of nonlinear … See more Surfactants and antifoaming agents PDMS is a common surfactant and is a component of defoamers.
