Abstract

The invention discloses a flexible smart film material with a photonic band gap structure and a preparation method of the flexible smart film material. The preparation method comprises the steps as follows: firstly, spherical particles are taken as raw materials, and a photonic crystal template is obtained through assembly; then the photonic crystal template is filled with a low-concentration polymer solution and a high-concentration polymer solution of the same polymer sequentially and then subjected to solidification treatment, a solidified photonic crystal template filled with the polymer is obtained and soaked in a solution capable of dissolving the spherical particles, a film without the photonic crystal template is obtained, and the flexible smart film material is obtained after cleaning and drying. The prepared flexible smart film material combines characteristics of a photonic crystal and the polymer and has double characteristics of regulation of a light propagation path and chemical energy driving for the film, the defect of single performance of the traditional material is overcome, and the driving direction is controllable by changing a film cutting direction.
