FIELD: microtechnology; manufacture of microchip electrode systems for microanalytical devices.
SUBSTANCE: proposed conducting composite incorporates elastomer, conducting polymer, and conducting carbon filler in the form of polymethyl methacrylate. Proportion of components is as follows, mass percent: conducting carbon filler, 95-97; elastomer, 1-2; polymethyl methacrylate, the rest. It is most reasonable to use glass-reinforced carbon or granular graphite as conducting carbon filler and polydimethyl siloxane, as elastomer. To facilitate its use conducting composite may be transformed to suspension in volatile concentrated solution or hexane or cyclohexane in dichloroethane. Resistivity of dried composite is 0.05 - 0.14 Ohm-cm.
EFFECT: facilitated preparation and use, enhanced chemical and biological inertness of composite.
