Abstract

The invention discloses a preparation method of a polyamide and graphene oxide combined photoelectric material, which relate to the field of preparation methods of photoelectric materials, and mainly aim at solving the problems that a polyamide photoelectric material prepared by a conventional method is poor in thermal stability, poor in conductivity and low in electrochromism response sensitivity. The polyamide and graphene oxide combined photoelectric material is prepared from acylating chlorination graphene oxide, diamine, diacid, calcium chloride, pyridine and triphenyl phosphate. The preparation method comprises the following steps of: firstly, preparing the acylating chlorination graphene oxide; secondly, preparing a primary product of the polyamide and graphene oxide combined photoelectric material; and thirdly, purifying and drying the primary product. The polyamide and graphene oxide combined photoelectric material has the advantages that electrochemical oxidation reduction reversibility is high, the response to color change in electrochromism is rapid, the color change sensitivity is high, and the state after the color change can be stably maintained for half a year. The polyamide and graphene oxide combined photoelectric material is applicable to the photoelectric field.
