Preparation method of compound nano film

Abstract

The invention discloses a preparation method of a compound nano film, and belongs to the field of electronic film materials. The method comprises the steps as follows: GOQDs (graphene oxide quantum dots) are assembled in a substrate with an LB (Langmuir blodgett) film method, and then conducting polymers are deposited on the GOQDs in a spin-coating manner, so that the compound nano film with the GOQDs tightly wrapped with the conducting polymers is formed. According to the preparation technique of the GOQDs / conducting polymer compound nano film, the defects in the prior art are overcome, large-area film formation can be implemented easily, the preparation method is reasonable, simple and easy to operate.

Description

technical field

[0001] The invention relates to the field of electronic film materials, in particular to a method for preparing a composite nano film based on graphene oxide quantum dots and conductive polymers. Background technique

[0002] Graphene oxide GO has good solution processability as a precursor for graphene preparation. In recent years, the research and development of new configurations of GO composite nanomaterials has become a hot spot in the field of functional materials research.

[0003] Graphene oxide quantum dots (Graphene oxide quantum dot, GOQD) are quasi-zero-dimensional nanomaterials, and the movement of electrons in them is restricted in all directions, so the quantum confinement effect is particularly significant and has many unique properties. Graphene quantum dots have important potential applications in the fields of biology, medicine, materials, and new semiconductor devices.
