Description
Technical field
The invention relates to a kind of antistatic coating, and particularly about a kind of antistatic coating that comprises ionic liquid, the formed antistatic film of antistatic coating thus, has the characteristic of high rigidity and low sheet resistance value.
Background technology
In recent years, improvement and lifting along with semi-conductor and photoelectric subassembly manufacturing technology, comprise liquid-crystal display (Liquid Crystal Display, LCD) and plasma display panel (Plasma Display Panel, PDP) in interior flat-panel screens, popularize gradually in modern's family and office.In order to prevent the panel surface of flat-panel screens be subject to the scratch of external force or bind with koniology, conventionally can before flat-panel screens, add the antistatic film of last layer scratch resistance due to static.In addition; antistatic film is except can be applicable to display surface, easily static electrification and also need the product of scratch resistance to avoid the static producing because of friction can make dust or chip be adsorbed on product as sunglasses, camera lens, automotive window etc. also often can paste one deck antistatic film.
In known techniques, to article, the method that particularly film material is given antistatic property has: in the raw material that forms article, add the methods such as the electroconductive stuffings such as carbon black, metal-powder, conductive metal oxide, interfacial agent, ionic liquid, and the antistatic layer that contains electroconductive stuffing in article surface setting, the methods such as antistatic layer that formed by interfacial agent.But above-mentioned the whole bag of tricks has problem miscellaneous.For example, in known techniques, in order to increase, the electroconductibility of film material is added metal in antistatic coating or nonmetallic conducting particles reduces surface resistivity.Yet particle or powder often can affect the optical property of film material, cause its transparency variation, and then affect the effect of optical articles.In addition, in the process of setting of film material, easily because hardening, not exclusively make surface hardness not enough.And add the methods such as interfacial agent or ionic liquid in the raw material that forms article, its antistatic property is easily subject to the impact of ambiance humidity, also have because of the cleaning of water, alcohols etc., the antistatic layer that makes to consist of interfacial agent or ionic liquid disappears, because of friction, hold caducous weather resistance deficiency or film material plays white mist and affects the problems such as transparency.And if by multilayered structure, with coating method repeatedly, manufacture antistatic film, in processing procedure, because needs are repeatedly coated with, will increase unnecessary manufacturing cost.Again, as the metal oxide of ITO (Indium Tin Oxide, tin indium oxide) has the transparency, and with electronic conduction as conductive mechanism, though be suitable for above-mentioned requirements, but the essential sputtering apparatus that adopts during due to masking, not only become numerous and diverse and manufacturing cost of processing procedure can improve.And the pliability that inorganic, metal oxide is filmed is low, when film forming on thin base material, films and may seriously split, and cannot represent electroconductibility.In addition,, because the adaptation of metal oxide and organic substrate is low, have and in interface, peel off the risk that the transparency is declined.
