Vacuum coating apparatus suitable for the conductive film flexible electronics
Vacuum coating equipment conductive film characteristics / cost than ITO transparent conductive film applicable to flexible electronic high-bandgap higher order metal oxides such as injection as indium tin oxide (ITO) formed in a very successful application of optoelectronics industry, covered the flat panel display, solar and a touch panel so the battery must be used. However, both transparency and electrical Subject thin film, the transparent conductive film is required to flexible electronic components must be provided with flexing properties, if the metal oxide thin film is still readily selected because of the bending defects, element rotatable about song number and the degree of bending will be restricted, thereby affecting the applicable range. In addition, indium oxide, indium tin commonly are rare, widely used after being prone to shortage of raw materials, prices drawbacks, developers comprising a transparent conductive film flexibility is important to the development of electronic technology flexible element .

Vacuum coating, vacuum coating plant type polymer material having conductivity range, such as polyacetylene (polyacetylene), polyaniline (Polyaniline), polypyrrole (polypyrrole), poly thiophene (Polythiophene), etc. However, given the need to take into account the properties of the transparent conductive and high degree, the most successful materials are Polythiophene series Poly (3,4-ethylenedioxythiophene) -PEDOT (product patterns for muddy and mostly Polystyrenesulfonicacid-PSS aqueous solution), the material and the industry, such as Agfa HCStarck Release may have conductivity close 1,000S / cm of the product can be used to produce a light transmittance of more than 80%, from about 200Ω / sq height and flexural resistance of the conductive substrate surface.
In recent years, Guangdong vacuum coating, vacuum coating equipment researchers began to notice ITO- -ITO metal multilayers, promotional advantage that light-transmitting properties, like flexural and electrically conductive, and wherein the conductive flexural resistance promotion more intuitive reasons, are derived from the metal thin film itself is excellent in characteristics. Metal - - Such increased translucency effect of suppressing dielectric from the dielectric multilayer film reflecting visible light, but may be varied spectrum of transmitted light transmitted through the optical design, resulting in selective transparency function.

Vacuum coating machines, vacuum coating plant: the development of flexible photovoltaic element, flexing can be used a transparent conductive film can be improved, however, a metal oxide electrode has been widely used nowadays, such as ITO, and can not meet this demand. Vacuum Technology and Its Application conductive film transparent solar coating machine element, these techniques include conductive polymer, an oxide - metal - oxide film multilayer technology, and the self-assembly nano silver silver nanowires, etc., can form a clear and a conductive thin film or mesh structure, and the characteristics and manufacturing cost than ITO, in the future are likely to be successfully applied on the photovoltaic element of flexing.
