In current work it was investigated the temperature dependence of special surface resistance compos- ites on the basis of gelatin with different content of Cu2S and CdS chalcogenide semiconductor nanoparti- cles. It was shown that, nanocomposites has posistor effect. It was defined that, posistor effect is the result of intermolecular influence in the boundary of polimer-nanoparticles phase and the reason of electrotransfer charge in such systems is polymer layer tunneling between nanoparticles before percolation threshold and percolation theory after percolation threshold.
