Property.Since nano-silver thread is a kind of direct band gap wide-band gap material, forbidden bandwidth reaches 3.37ev, in the transmission of visible light wave range
Rate is very high, up to 90% or more, and raw material have it is from a wealth of sources, resourceful, nontoxic, pollution-free, environmental-friendly, in hydrogen etc.
Stability is better than the advantages of indium tin oxide films form in gas ions.Therefore, nano-silver thread electrically conducting transparent form is considered as most
It is possible that the form material of substitution tin indium oxide, the application of nano-silver thread electrically conducting transparent form will bring significant society's effect
Benefit.Currently, prepare the generally existing instrument and equipment valuableness of nano-silver thread, complex technical process, it is at high cost the problems such as, be unable to satisfy big
Scale prepares the actual demand of high quality nano silver wire.Hence it is imperative that developing a kind of technology, it is equal can efficiently to prepare size
One, the nano-silver thread of good conductivity.Prepare high shielding effect flexibility form film using nano-silver thread simultaneously there is also technologies it is immature,
The problems such as film performance of preparation is poor.
