Method for quickly depositing graphene on glass surface through metal-free catalysis

Abstract

The invention provides a method for quickly depositing graphene on a glass surface through metal-free catalysis. The graphene is quickly deposited on the quartz glass surface by using a chemical vapor deposition (CVD) method under the condition free of an assist of a metal catalyst. The method mainly comprises the following process steps of (1) putting a clean quartz glass sheet on a special bracket, putting the quartz glass sheet and the bracket into a quartz tube and making the glass surface vertical to the horizontal air direction; (2) introducing a carrier gas into the quartz tube, heating the quartz tube to a reaction temperature from a room temperature and introducing a carbon source gas; and (3) quickly growing the graphene on the glass surface through an atmospheric chemical vapor deposition method under the condition free of the assist of the metal catalyst. The process is simple in process and easy to operate; and the conductivity of the graphene glass surface is improved on the premise of ensuring high light transmittance of the graphene glass. The graphene conductive glass with good light transmittance has potential application in multiple fields, such as a photocatalytic substrate and an anti-fog window.

Description

technical field [0001] The invention relates to a method for directly and rapidly depositing graphene on a glass surface, and belongs to the technical field of material chemical preparation. Background technique [0002] Glass is a relatively transparent solid substance that forms a continuous network structure during melting, and is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. Glass is one of the indispensable materials in daily life, and has a wide range of applications in the fields of architecture, home furnishing and decoration. Traditional glass has the characteristics of insulation, hydrophilicity and high transparency. A layer of transparent conductive film is coated on the surface of the glass, and the obtained transparent conductive glass is widely used in liquid crystal displays, solar cells, optoelectronics and various optical fields. The most common conductive glass is ITO glass, that is, a layer of indium ...
