Claim 3:
4. An electrically conductive composite material, comprising:
polyaniline and a metal-organic framework, wherein the metal-organic framework is MOF-5;
wherein the polyaniline is integrated into pores of the MOF-5 and the MOF-5 has a formula Zn4O(BDC)3, where BDC is 1,4-benzenedicarboxylate;
wherein the electrically conductive composite material has:
an electric conductivity of about 4.69×10−9 S cm−1,
an ionic resistance of about 100 ohms, and
a minor powder x-ray diffraction peak in the range of 5° to 10°;

wherein the electrically conductive composite material is obtained by:
mixing, by sonification, a first solution of polyaniline and dimethylformamide to form a second solution;
mixing, by sonification, the second solution with 1,4-dicarboxylic acid;
mixing, by sonification, a third solution of zinc nitrate hexahydrate with dimethylformamide;
mixing, by sonification, the second and third solutions to form a fourth solution;
solvo-thermal processing the fourth solution at a temperature in the range of 80-120° C. for a time in the range 12-48 hours;
cooling the fourth solution; and
filtering and washing the cooled fourth solution to isolate the electrically conductive composite material.
