Beschreibung

Allgemeine Beschreibung

Poly(dimethylsiloxane) (PDMS), also known as dimethicone, is an organosilicon compound that is widely used as a siloxane based elastomer. It is a hydrophobic material with attractive physical and chemical properties such as elasticity, optical transparency, tunable surface chemistry, and low electrical conductivity.[1][2][3]

Anwendung

PDMS can be used in microfluidic devices,[4] nanolithography,[5] and other membrane based applications.[6][7]
