Description
Technical field
The present invention relates to a kind of conductive coating field, in particular to a kind of conductive coating with strong attachment fastness.
Background technique
Conductive coating is the special functional coating that develops rapidly with modern science and technology, grinding in recent decades
Study carefully and develop, conductive coating oneself be applied in a variety of military, civilian industrial circles such as electronics, electric appliance, aviation, chemical industry, printing.
Existing transparent conductive material application in using it is most common be ITO Coating Materials, its preparation method is transparent organic thin
The product that transparent indium tin oxide (ITO) conductive film coating obtains is sputtered on membrane material.The characteristics of product, is, in PET film
For upper, its thicker sheet resistance of ito film layer is smaller, but light transmittance also becomes smaller.Such as: high impedance ITO conductive film (PET-ITO),
300 ~ 500 Ω of sheet resistance/mouth, light transmittance >=86% indicate hardness >=3H, heat curling≤10mm；
Low ESR ITO conductive film (PET-ITO), 90 ± 15 Ω of sheet resistance/, light transmittance>=80%, mist degree<2%, width 406/
360 ± 2mm, curling≤10mm；Ito film light transmittance >=90% of most significant end, sheet resistance≤100 Ω/；
But there are the deficiencies of several aspects for ito film, first is that since its coating plates firmly, bending is poor, second is that spreading area is limited, three
It is that indium tin resource is deficient, is unsuitable for sustainable development equipment valuableness, process flow is long, and cost drop is not got off, Gu and research and develop ITO
Substitute have become the emphasis paid close attention in industry.
So far, being expected to substitution ITO product mainly has: conducting polymer, carbon nanotube (CNT), graphene and metal
Nano wire, a large amount of research of everyway investment and industrialization as early as possible:
1. conducting polymer: have good electric conductivity and has higher light transmittance in the case where solid content is lesser × secondary, it is so conductive
The adhesive force of high molecular material itself and all kinds of substrates has limitation, it must by and other high molecular materials combination ability
Have good adhesion, this × the electric conductivity and light transmittance for just reducing it.
The product introduction that can be seen at present: the positive nanometer PTT-023 in Shanghai Shanghai is compounded using conducting polymer and ITO material
Manufactured coating, sheet resistance: 80 ~ 400 Ω cm light transmittances: 80-85% indicates 2 ~ 3H of hardness water paint > 1H oiliness.
Also have patent introduction: using conducting polymer and ×× particle compositional liquor, light transmittance is up to 90.1%, sheet resistance 240
Ω/□；
Above-mentioned technical indicator is the basic performance close to ito film, still there is certain gap.
2. carbon nano-tube film
Theoretically, single armed carbon nanotube has excellent translucency and electric conductivity, but after film forming, due to film thickness and thoroughly
Light rate and resistance have direct correlation, Gu this needs to grope on film-forming process to obtain optimal balance point.
Su Zhouhan receives material Science and Technology Ltd. and technically has breakthrough and initially entered the film of yield 500mm wide,
It is introduced that light transmittance 89%, 200 Ω of sheet resistance/, mist degree < 1% substantially achieve the technical parameter of ito film；In price with
Ito film is close, and comparative advantages are little.
3. graphene film
Graphene has the characteristics that high conductivity, high tenacity, high intensity, high transparency；Undoubtedly a key areas and state
The important directions of family's 21st century new material development, but the product sufficiently solves volume production technology at present still in experimental stage
A longer process is also needed with production cost is reduced.
4. current most competitive alternative ITO's surely belongs to silver nanowires scheme, in recent years, this preparation process day
Gradually mature, volume production have a feasibility, at the same cost can also sharp fall, it is available that technology controlling and process is mixed with using polyalcohol
The line footpath of various combination is than silver wire, and this kind of silver wire is compounded with high molecular polymer, can get corresponding high transparency, high conductivity
Coating.Since the specific surface area of silver nanoparticle is very big, only needs minimal amount of silver wire that can be coated in coating and applied with other metals
Expect identical spreading area, Precious Metals Resources are greatly saved, in addition, coating can neatly select roller coating, showering, spraying to step on work
Skill, than ITO carbon nanotube form a film it is simpler, conveniently and not restricted by working (finishing) area, and use water soluble polymer aggregates into
Membrane substance then meets environment friendly and pollution-free requirement.
