[0037] The present invention firstly provides a method for preparing a fluorine-free superhydrophobic flexible photothermal film, comprising the following steps:
[0038] S1. Dispersing the photothermal material in an organic solvent to obtain a first dispersion;
[0039] S2. Adding a silane coupling agent to the first dispersion for dispersion to obtain a second dispersion;
[0040] S3, coating the second dispersion liquid on the surface of the flexible substrate and performing curing treatment.
[0041] In the present invention, the photothermal material is dispersed in the organic solvent first, and then the silane coupling agent is directly added for reaction. On the one hand, the addition of the silane coupling agent can reduce the surface energy of the coating and increase the hydrophobicity; The adhesion between nanomaterials and the substrate improves the mechanical strength of the coating; during the coating process, photothermal materials can spontaneously aggregate...
