Value can expand the application space of glass, cause glass industries and added from the low value-added economizing type height that is applied to of high-volume
It is worth the revolutionary change of application.
Directly Graphene glass can be prepared in glass surface growth graphene.Liu Zhongfan etc. utilizes chemical vapor deposition
Method glass surface catalytic pyrolysis is overcome by the accuracy controlling to reacting gas concentration, growth temperature and growth time
Forerunner's ability of immigrants is low, and carbon fragment is in the problems such as substrate surface transfer ability is weak, and success is real on pyroceram and simple glass
The controllable growth for having showed high-quality graphene film grows size and all well-proportioned graphene disk of distribution.This growth
The Graphene glass that method obtains, the excellent specific properties such as the interfacial contact with glass and graphene is good, interface is pollution-free, still
Complex process, equipment requirement is high, expends big, unsuitable practical application.Liquid phase film or transfer also can be used in Graphene glass
Method obtains, i.e., coats grapheme material or be transferred on glass.For example, Li et al. people utilizes LB membrane technologies in gas
Liquid interface is prepared for graphene film, is from the bottom up picked up graphene film with glass to obtain Graphene glass.Such method
The hydrophobicity of glass surface, graphene can not be overcome to paste the problems such as not close with glass surface, the graphene film of acquisition is not
There are problems that surface and interface pollution avoidablely, to seriously affect the performance of Graphene glass.Therefore, develop a kind of operation letter
New method single, at low cost, yield is high is that one in presently relevant application study is crucial.
