[0002] There are few reports on the combination of unsubstituted thiophene and inorganic materials, all of which are compounded in organic solvents (chloroform) or thiophene directly with montmorillonite at the boiling point of thiophene; unsubstituted polythiophene has poor solubility in water, Usually in organic solvents such as chloroform or by electrochemical polymerization, when thiophene is polymerized in chloroform solvent, it is often necessary to evaporate the chloroform or dispose of it by other means, which increases the time and cost of the reaction, which is not conducive to industrialization; and When electrochemical polymerization, it is necessary to seek a suitable solvent, and there are too many variable factors, it is difficult to guarantee the quality of polythiophene, and the industrialization is also limited; the compatibility of inorganic fillers and polythiophene is poor, and the stability of the finished product is low, so The purpose of the present invention is to endow the composite material with new functions on the basis of improving the stability and compatibility of polythiophene and inorganic fillers, so as to enhance its applicability in different fields
