Abstract: A charging post controller with various functional modules connected by a PCB, and a charging post thereof. The controller includes a monitoring unit (1), a direct-current main loop unit (2) and a mounting and fixing unit (3), wherein the monitoring unit (1) comprises a PCB (11) and an electronic circuit forming electrically connected functional modules (4), and the functional modules (4) are mounted on the mounting and fixing unit (3), to form a laminated arrangement structure among the monitoring unit (1), the direct-current main loop unit (2) and the mounting and fixing unit (3). A charging post using the controller has a relatively high degree of integration, relatively small overall volume and relatively low comprehensive cost, and is relatively easily promoted and applied.

Abstract: The present disclosure provides a three-dimensionally arranged nanoparticle film and a preparation method and use thereof, and belongs to the technical field of nanophotonics. The preparation method includes the following steps: coating nanoparticles with hydrophobic molecules, and dispersing in an organic solvent to obtain a modified nanoparticle dispersion; conducting a surface treatment on a three-dimensional template to obtain a hydrophilic three-dimensional template; and adding water to a surface of the hydrophilic three-dimensional template to form a water film, adding the modified nanoparticle dispersion dropwise on a surface of the water film to conduct self-assembly, and removing the water film to obtain a three-dimensionally arranged nanoparticle film with an array structure.
