Abstract
A method for enhancing the conductivity of MOF-5 by the development of an MOF-5 polymer composite material. The composite material incorporates a conductive polymer, preferably polyaniline, in the solvo-thermal synthesis pathway of MOF-5. The electrically conductive MOF-5 composite exhibits electric conductivity three orders of magnitude higher than that of MOF-5 while maintaining the crystallinity, robustness, and thermal stability of MOF-5.
