        Abstract
        A comparative study on 4-N,N'-dimethylamino-3- acetamidonitrobenzene (DAN) doped polycarbonate (PC) and DAN doped poly-methyl-methacrylate (PMMA) shows that electrical poling enhances electrical conductivity. This enhancement is mainly due to the interaction between the guest molecules and the host polymers. In this work it has been found that the increase in conductivity is higher in DAN/PC than in DAN/PMMA. This is due to the hydrogen bonding which occurs between the carbonyl group of PC and the nitro group of DAN. Hydrogen bonding enhances also the poling efficiency of DAN molecules in PC. Besides the increase of the magnitude of the electrical conductivity, a hysteresis loop is obtained..
