Flexible polyvinyl chloride heat storage film with photoelectric double response and preparation method of flexible polyvinyl chloride heat storage film

The invention discloses a flexible polyvinyl chloride heat storage film with photoelectric double response and a preparation method thereof, and belongs to the technical field of photoelectric response materials. The preparation method comprises the following steps: dissolving polyvinyl chloride, pyrrole, polyethylene glycol and an organic phase change material in an organic solvent, uniformly coating the mixture on the surface of a substrate material through a film coating device, and immersing the whole substrate material in an aqueous solution in which a catalyst is dissolved to obtain the film. The flexible heat storage film with light absorption capacity and conductivity is prepared through a one-step method, the process of secondary modification of the polyvinyl chloride film is omitted, meanwhile, the organic phase-change material exists in the film, so that the coating has certain heat storage capacity, the process of preparing a composite phase-change material is omitted, the time needed in the film
