Abstract In this work, we used the design strategy “doped nonpolar polymers” and synthesized polyurethane elastomers (PUEs) by doping with highly polar aromatic molecules such as benzoic acid (BA), 4(para)-nitro-benzoic (PNBA), 3, 5-di-nitro-benzoic (3, 5-DNBA) using solution casting method. The effect of each molecule in three different weight percentages 2%, 4%, 6% on electrical thermo-mechan...
