Description
Technical field
This utility model belongs to electronic technology field, particularly relates to a kind of conducting film, specifically, relates to a kind of plated surface
The nano-silver thread conducting film of copper.
Background technology
Along with increasing electronic product enters the life of people, human-computer interaction function just becomes increasingly there is demand,
And modal human-computer interaction interface is exactly contact panel.Wherein consumer electronics product is as burning the hotest man machine interface
Carrier, it makes touch screen with the most use be resistive touch screen and capacitive touch screen at present.For this two classes touch screen mesh
The main flow nesa coating used on front market is all ITO conducting film, and ITO conducting film is as main product, has the transparency
Good, electric conductivity is excellent, and the advantage such as processing technique is ripe, but on the other hand, ITO itself, as ceramic material, has
The defect of mechanical strain ability, i.e. also can be easier to crackle occur under less external carbuncle.And replacing as ITO conducting film
Have novel transparent conductive film materials such as nano-silver thread, metal grill, CNT, Graphene and PEDOT for material, wherein with
Nano-silver thread is the most ripe.Nano-silver thread conducting film the most of the prior art exists starches, with silver, electrically conduct instability or adhesion
The problems such as power is the best, and if print silver slurry if, the production of automatization relatively difficult to achieve in terms of making technology, be unfavorable for efficiency
Lifting, and the management and control of cost.
Summary of the invention
For defect and the deficiency of prior art, the utility model proposes a kind of new technical scheme, i.e. a kind of plated surface
The nano-silver thread conducting film of copper.
A kind of nano-silver thread conducting film of copper coating, including transparent base, described transparent base be glass or
PET, COP, PMMA, PC high-molecular organic material or sapphire inorganic material, stack gradually in the side of described transparent base
Structure is provided with fall mist hardened layer, nano-silver thread layer, OC layer and copper conductive layer, and described nano-silver thread layer is mutually inlayed with described OC layer
Being embedded in together, described copper conductive layer is covered on described nano-silver thread layer and described OC layer.
The thickness of above-mentioned fall mist hardened layer is 0.5-5um, and the thickness of described nano-silver thread layer is 20nm-500nm, described OC
The thickness of layer is slightly less about 5%-20% than nano-silver thread layer, and described copper conductive layer thickness is 0.05-2um.
The generic term that above-mentioned PET, COP, PMMA, PC high-molecular organic material is in industry, as PET refers to poly-to benzene
Naphthalate, belongs to crystal type saturated polyester, and for milky or light yellow, the polymer of highly crystalline, surface is smooth to be had
Gloss, is a kind of resin common in life.
The material of above-mentioned OC layer is polymethyl methacrylate, and described fall mist hardened layer pencil hardness is at least up to 3H.
This utility model is equivalent to nano-silver thread layer as transparency conducting layer, and copper conductive layer is just worked as ultralow sheet resistance
Routing layer, nano-silver thread has low square resistance relative to the ITO material of main flow, resistance to around the advantage rolled over, and on nano-silver thread layer again
Plated with copper then can simplify work flow during follow-up making contact panel, is greatly saved processing cost；And nanometer can also be solved
Silver wire conducting film starch instability in electrical contact or bad etc. the problem of adhesion with silver；And also can be significantly in terms of processing procedure
Simplify production link, it is easier to realize automated production.
Due to above-mentioned beneficial effect, this utility model is widely used in various conducting film.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Reference: 1-transparent base；Mist hardened layer drops in 2-；3-nano-silver thread layer；4-OC layer；5-copper conductive layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings, it is further elucidated with detailed description of the invention of the present utility model.
As it is shown in figure 1, be cross-sectional view of the present utility model, the nano-silver thread conducting film of a kind of copper coating,
Including transparent base, described transparent base is PET high-molecular organic material, stacks gradually knot in the side of described transparent base
Structure is provided with fall mist hardened layer, nano-silver thread layer, OC layer and copper conductive layer, and described nano-silver thread layer is mutually inlayed with described OC layer
Together, described copper conductive layer is covered on described nano-silver thread layer and described OC layer.
The thickness of above-mentioned fall mist hardened layer is 2um, and the thickness of described nano-silver thread layer is 200nm, the thickness of described OC layer
Slightly little by about 10% than nano-silver thread layer, described copper conductive layer thickness is 1um.
The material of above-mentioned OC layer is polymethyl methacrylate, and described fall mist hardened layer pencil hardness is 4H.
Making programme of the present utility model is: the surface of base material is carried out plasma cleaning, then hard in the coating of its surface
Change layer, hardened layer is coated with nano-silver thread layer, nano-silver thread layer is coated with OC layer, sputter or copper steam-plating conduction on OC layer
Layer.
It should be pointed out that, for those skilled in the art, before without departing from this utility model principle
Putting, it is also possible to make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
