Crosslinkable polar siloxane copolymers for ion detection devices

Abstract

Functionalized polysiloxanes can be used as sensing membranes in ion‐sensitive field effect transistors (ISFETs). A new 0 ue‐Si and reproducible route for obtaining well‐de‐fined polysiloxane copolymers–the anionic copolymerization of cyclotetrasiloxanes with different side groups (one of which is shown in the Figure)–is reported and the characterization and use of the copolymers in CHEM‐FETS described. magnified image
