Controlling the polymerization of aniline in presence zirconium-based metal–organic frameworks (Zr-MOFs) using polystyrene sulfonic acid as a dopant resulted formation new type free-standing thermoelectric composite film. Polyaniline chains interpenetrate into Zr-MOFs to enhance crystallinity polyaniline, resulting an improved degree electrical conductivity. In addition, inherent porosity functions suppress increase thermal conductivity, thus dramatically promoting negative Seebeck coefficient. When 20 wt % Zr-MOF was used, power factor up 664 μW/(m K2) obtained, which accompanied by surprisingly large, The class MOF-based composites offers direction for developing types efficient materials.
