ENHANCED PERFORMANCE OF POTASSIUM CHEMFETS BY OPTIMIZATION OF A POLYSILOXANE MEMBRANE

[摘要] In a way to enhance performance of CHEMFETs based on chemically modified polysiloxane membrane matrix, the effect of the polarity of polysiloxane material on the membrane homogeneity in relation to the covalent binding of the ionophore was investigated. Potassium sensors with the membrane based on the new polysiloxane showed a response with a Nernstian slope in a whole investigated range of cation activity. A new polysiloxane as the membrane matrix improved its homogeneity and increased the yield of functioning CHEMFETs.
