Tianjin University of Technology's new film makes the phone screen softer
The mystery of the touch screen of the mobile phone is on a thin conductive film. At present, indium tin oxide (ITO) films are widely used for transparent conductive films widely used in the market, but indium is a rare metal, and its recoverable reserves are continuously reduced. As a better substitute for performance, carbon nanotube (CNT) conductive film has gradually attracted people's attention in recent years.
Recently, the team of Tianjin University of Technology professor Yan Hongzhang developed a wearable flexible photoelectric film preparation technology, combining a simple rapid spray and acid treatment technology, combined with the bar coating method and acid treatment optimization technology, can be large area fast A carbon nanotube flexible transparent conductive film is prepared. CNT film can overcome many shortcomings of ITO film, and can improve the conductivity of flexible carbon nanotube conductive film while maintaining high light transmittance. At the same time, it can be used to make a flexible and flexible touch screen, and it can make the screen quality of the mobile phone clearer and more vivid. According to reports, the film produced by this technology has broad application prospects in the future of wearable device manufacturing.
