Flexible electronic technology can lead a subversive electronic technology revolution,flexible electronic equipment has become a new wave of electronic products,in information technology,energy,medical,national defense and other fields with a wide range of applications.With the continuous progress and improvement of electronic technology,more and more focus is placed on lightweight and mobility of electronic products.Traditional electronic products have their own difficult pain points,hard,rigid,not resistant to bending.Compared to traditional electronic products,flexible electronic products are more energy saving,convenient,diversified,and easy to operate.Flexible electronics not only focus on the improvement of integration and performance,but also pay attention to the development of ultra-light,ultra-thin,drop resistance,folding,flexural and irregular shape,constructing distributed system,which will open up many new electronic application fields.Flexible electronic technology will inevitably become a key driving force for the growth of high-tech industry in the future.As an electrode material,flexible transparent conductive film(TCF)is the core component of many flexible electronic devices and the key to the flexibility of rigid electronic devices.At present,indium tin oxide(ITO)film,which accounts for the largest market share of flexible transparent conductive film,is a planar structure oxide ceramic conductive material.During repeated bending,the surface structure is prone to breakage,which affects the performance and service life of the conductive film.Based on this,this paper has developed a variety of new template technologies to prepare highly flexible transparent conductive films,and successfully applied to thin-film solar cells,electrochromic devices,e-books and self-power nanosystem.The main research results are as follows:1)Fully flexible CdSe/CdS quantum dot sensitized solar cell(QDSSC)based on CuS nanosheet grid flexible transparent conductive film.2)Preparation of dye-sensitized solar cells(DSSC)based on CuS nanosheet grid flexible transparent conductive film by large-area controllable rectangular crack template method.3)Preparation of large-area fully flexible ITO-free electrochromic device(ECD)based on the controllable rectangular crack template method.4)Flexible dye-sensitized solar cell(DSSC)self-driving light response electrochromic smart window system.5)Large-area ITO-free self-driving light-responsive electrochromic intelligent system based on fiber solar cells.6)Triboelectric nanogenerator(TENG)control system based on stretchable,degradable,ultra-high stability and biocompatible silk composite protein film.7)Flexible biological protein display device based on composite modified silk flexible transparent conductive film.
