ION EXCHANGING ELECTRODES FROM POROUS-GLASS

Low frequency electrical properties of numerous organic and biological materials depend on the transport of ions. Commonly used electrodes, such as metal films or Nesa glass, are blocking ones. When studying th in layer samples one must seriously account for, generally unknown, in fluence of an electrode. It has been shown previously that ion-exchang ing membranes may serve as ion-injecting electrodes. However, problems with supporting of thin samples were reported. Porous glass has been used for preparation of ion-exchanging electrodes, for the studies of liquid crystals and polymers.
