The article presents the study of electrical conductivity of composites made electroconductive. Prepared systems for polymer composites made of nonwoven polypropylene based on a weight of 35 glm2 - PP containing: as a conductive polymer: Polyaniline in the form of composite with carbon black - PANIC as the polymer matrix: poly (n-butyl methacrylate) - PMB, poly (vinyl acetate) - POW, poly (ethylene-vinyl acetate) - EVA were tested for reaction to the presence of selected vapors organic substances, such as cyclohexane and acetone in various conditions of temperature and vapor concentrations of these substances. It has been shown satisfactory response to cyclohexane vapor at normal temperatures fur the index of the polymer designated schematically PANIC + PMB + PP, while for higher temperature showed a good response rates indicated schematically: PANIC + POW + PANIC + PP and EVA + PP. In the case of acetone vapor at a temperature of about 22.0 °C showed a satisfactory response to all of the indicators used polymer. Indicators developed polymer can only be used as selective sensors in gas filters respiratory protection equipment. They can be a detector when connected to a power supply system and the ratio of the output signal from the sensor polymer.
