Embodiment 1

[0025] The seawater power generation device based on the composite conductive film of carbon black graphene / water-based polyurethane coating provided by the invention, its preparation method comprises the following steps:

[0026] (1) Disperse a certain mass of water-based polyurethane coating into distilled water, and prepare a dispersion of water-based polyurethane coating with a mass-volume ratio of 0.001-0.023g / mL.

[0027] (2) Dispersing the mixed powder of graphene and carbon black into the dispersion liquid of the water-based polyurethane coating in step (1), the mass of the mixed powder of graphene and carbon black accounts for the total matter dispersed in the dispersion liquid The mass fraction of the carbon black is 40%, and it is dispersed by ultrasonic to form a stable dispersion; wherein the mass ratio of graphene and carbon black is 2:1.

[0028] (3) Apply the stable dispersion obtained in step (2) to the substrate, and dry naturally in the air to form a composi...

Abstract

The invention discloses a carbon black-graphene / aqueous polyurethane coating composite conductive thin film based seawater power generation apparatus, and a preparation method and an application therefor. The seawater power generation apparatus is prepared by the steps of dispersing the aqueous polyurethane coating into a dispersion liquid firstly; then enabling the dispersion liquid, graphene and carbon black to be mixed and dispersed; next, coating a substrate with the mixed dispersion liquid, and drying the substrate naturally to obtain the carbon black-graphene / aqueous polyurethane coating loaded composite conductive thin film; and then further assembling the seawater power generation apparatus. By making full use of the interface charge transmission generated when the composite conductive thin film is washed by sea water, the output of the current and voltage signals is realized; when the thin film is washed by seawater, the seawater power generation apparatus is formed; the seawater power generation apparatus has simple preparation method and low cost; the large-area preparation of the seawater power generation apparatus can be realized; and meanwhile, the seawater power generation apparatus is excellent in performance, and can be applied in power generation on coastlines, rocks, ships, sea islands and the like, so that the utilization of the inherent source of the sea is improved.

Description

technical field [0001] The invention belongs to the field of new material technology and new energy technology, and specifically relates to a seawater power generation device based on carbon black graphene / water-based polyurethane coating composite conductive film and its preparation method and application.
