METHOD FOR CONTROL OF ELECTROCONDUCTIVE POLYMER COMPOSITE MATERIALS Russian patent published in 2015 - IPC G01N25/72 

FIELD: electricity.

SUBSTANCE: method for control of electroconductive polymer composite materials includes: installation and fixation of current electrodes at opposite sides or at one side of the controlled facility, installation of two measuring electrodes at one or two surfaces of the controlled facility, simultaneous measurement of potential difference between measuring electrodes and current intensity between current electrodes, determination apparent resistance between measuring electrodes by dividing potential difference by current value between current electrodes, identification of defects in the material against value of apparent resistance, current and measuring electrodes are interconnected rigidly, the complex of current and measuring electrodes is moved along surface of the controlled facility, measurement of potential difference between measuring electrodes and current intensity between current electrodes is repeated many times in order to identify defects in the material for the whole facility.

EFFECT: improved reliability is ensured for state identification of facilities made of electroconductive polymer composite materials.
