Description
Technical field
The present invention relates to flexible transparent conducting film technical field, and more particularly to a kind of modified nano silver wire nesa coating
And the method for improving the electric conductivity and inoxidizability of nano silver wire nesa coating.
Background technology
Transparency electrode refers to while having an electron-like original paper of good electric conductivity and translucency.It is solar-electricity
One of essential element of the photoelectric functional device such as pond, display, touch-screen and light emitting diode, thus widely closed
Note.Indium tin oxide (ITO) transparent conductive film have higher light transmittance (>85%) with relatively low surface resistance (10ohm/
Sq), application is had been commercialized.But, due to its fragility (resistance is sharply increased below for bending or folding), production cost height and indium
The shortage of resource, thus it cannot be used for flexible, wearable electronic device.In recent years, ITO material is may replace in order to find,
People studied macromolecule conducting polymer, CNT, graphene, metal grill and metal nanometer line transparent conductive material.
In these materials, the stability of conductive polymer polymer not can solve always；CNT and graphene are current
Production technology it is also immature, and production cost is high；Metal grill line width is typically larger than 5 μm, there is obvious unauspicious interference existing
As.Nano silver wire conducting film has excellent conduction and heat conductivility, is the preferred material for preparing flexible transparent conductive film in the recent period
Material, great commercial applications potentiality.
At present, the preparation method of nano silver wire nesa coating is to be applied nano silver wire conducting film by liquid phase processing mode
Cloth forms the grid of nano wire-nano wire (NW-NW) random crosslinking in solid substrate.The sky that light passes through nano silver wire grid
Effusion crosses substrate, thus the light transmittance of conducting film depends on the factors such as surface density, diameter and the length of nano silver wire.Electronics along
Nano silver wire is transmitted, then pass to by NW-NW crosspoints other nano silver wire, therefore nano silver wire nesa coating is led
Electric energy power depends primarily on the contact resistance in NW-NW crosspoints.At present, prepare the more ripe method of nano silver wire be polyalcohol also
Former method, i.e., be prepared under polyvinylpyrrolidone (PVP) assistance by reduction of ethylene glycol silver nitrate.In the method,
PVP is as the stabilizer of nano silver wire and the structure directing agent of crystal growth, thus its introducing is successfully to prepare nano silver wire
Key point.But, remaining PVP is difficult to be removed by conventional washing methods.On the one hand, it is adsorbed by silver-O keys
Nano silver wire surface, forms a layer insulating.The insulating barrier causes NW-NW crosspoints to form the silver-colored boundaries of nonideal silver-PVP-
Face, so as to generate larger contact resistance, seriously hinders conduction of the electronics between nano wire and nano wire.The opposing party
Face, in addition, PVP are the macromolecules of a long-chain, it is impossible to the protective layer of densification is formed on the conductive film surface of nano silver wire, from
And effectively completely cut off air and moisture.This results in the more active nano silver wire of chemical property and is oxidized easily in atmosphere, from
And reduce the electric conductivity of transparent membrane.As can be seen here, contact resistance big between NW-NW and nano silver wire conducting film itself are poor
Stability be to influence the subject matter that faces of nano silver wire nesa coating practical application.
The content of the invention
It is an object of the invention to provide a kind of side for the electric conductivity and inoxidizability for improving nano silver wire nesa coating
Method, the method can be effectively reduced the contact resistance between NW-NW, strengthen the aerial antioxygen of nano silver wire nesa coating
The property changed.
Another object of the present invention is to provide a kind of modified nano silver wire nesa coating, this passes through modified Yin Na
Light transmittance height, good conductivity, the anti-oxidant and crooking ability of rice noodles nesa coating are strong, with good application prospect.
The present invention realizes above-mentioned purpose using following technical scheme.
The present invention proposes a kind of method for the electric conductivity and inoxidizability for improving nano silver wire nesa coating, and it includes：
To NaBH of the alcohol-water as mixed solvent4Solution carries out the first subsurface to nano silver wire nesa coating
Processing；
It will be contacted by the nano silver wire nesa coating of surface treatment for the first time with the solution of n- alkyl hydrosulfides, progress the
Secondary surface treatment.
The present invention proposes a kind of modified nano silver wire nesa coating, passes through above-mentioned raising nano silver wire nesa coating
Electric conductivity and the method for inoxidizability prepare.
A kind of modified nano silver wire nesa coating of the embodiment of the present invention and leading for raising nano silver wire nesa coating
Electrically and the beneficial effect of method of inoxidizability is：There is provided a kind of electric conductivity for improving nano silver wire nesa coating and anti-
The method of oxidisability.First, to NaBH of the alcohol-water as mixed solvent4Solution is carried out to nano silver wire nesa coating
It is surface-treated for the first time.PVP is adsorbed onto silver surface by its carbonyl, forms strong silver-O keys.The NaBH of selection4Can be by PVP
In the paired metal of carbonyl reduction to metal with strong compatibility there is the hydroxyl of weak compatibility so that PVP can be from silver
Nanowire surface is removed.Remove after PVP, NW-NW crosspoints are changed into preferable Yin-silver from the silver-colored interfaces of nonideal silver-PVP-
Interface, so as to effectively reduce the contact resistance in crosspoint.Secondly, it will be led by the nano silver wire being surface-treated for the first time is transparent
Electrolemma is contacted with the non-aqueous solution of n- alkyl hydrosulfides, is carried out second and is surface-treated.N- alkyl hydrosulfides are matching somebody with somebody for small molecule
Body, and its sulfydryl can form strong silver-S keys with silver effect.Thus, n- alkyl hydrosulfides can be in nano silver wire conducting film table
Water, oxygen and other corrosive ions and nano silver wire that face is formed in one layer of fine and close hydrophobic protective layers, obstruction atmospheric environment
Conducting film is contacted, so as to improve the inoxidizability of nano silver wire conducting film.Moreover, the modification of n- alkyl hydrosulfides is to nesa coating
Surface resistance influences very little, can ignore.In addition, the modification of n- alkyl hydrosulfides is gentle solution processing procedure, nano wire is not influenceed
The microstructure of nesa coating, thus remain the original high transmission rate of conducting film.
