Abstract
The invention discloses a kind of touch-screen UV curing nano silver wire slurries and preparation method thereof, the method is in silver nitrate/polyol systems, using photolytic activity prepolymer as nano-silver thread growth templates, using polyalcohol as reducing agent, after the completion of reaction, by system centrifugation, polyalcohol supernatant is removed, the compound of nano-silver thread/photolytic activity prepolymer is obtained.The light-initiated monomer of this compound addition, light trigger, solvent and related auxiliaries, this slurry can as needed be made the products such as the electrically conductive ink or conducting resinl of light-initiated solidification.Nano-silver thread compound prepared by the present invention, the absorption to nano-silver thread and parcel using prepolymer, nano-silver thread has reached good dispersion in system, have good uniformity, can be used directly to carry out formulated product simultaneously, process is simple, with good industrial prospect.
Description
Technical field
The present invention relates to nano-silver thread field, and in particular to a kind of touch-screen UV curing nano silver wire slurries and its preparation
Method.
Background technology
Touch-screen is widely used on various digital information systems as a kind of new human-computer interaction interface, is formed
Huge market.Touch-screen generally using ITO (tin indium oxide) as transparency electrode, but indium metal mineral reserve are increasingly
It is few, will be exhausted in the year two thousand twenty or so.Therefore, each major company in the whole world and colleges and universities and research institution are all striving to find ITO's
Substitute, as new transparent electrode material.
From the point of view of current progress both domestic and external, ITO newly replaces material to focus primarily upon five kinds of technologies, including wire netting
Lattice technology（Metal Mesh）, carbon nanotube technology, conducting polymer technology, Graphene technology and nano-silver thread technology.Compare
Compared with for, the single-layer graphene that larger area is prepared at present is also highly difficult, and cost is very high, it is difficult to industrialize；Conduction is poly-
Compound resistance value is higher, at the same electric conductivity have through when relaxation phenomenon；Metal grill technology has a volume production prospect, but light transmittance
It is low, it is difficult to meet high-end requirement；The resistance of carbon nanotube technology face is higher, it is difficult to for touch control line.Nano-silver thread has very excellent
Elegant electric conductivity, its face resistance is very easy to reach 100 Ω/below sq, even 50 Ω/below sq, is made nano-silver thread
After slurry, can be applied on base material by way of intaglio or slot coated, thickness can accomplish 0.1 ~ 1 μm, width
