PEDOT/PSS水性分散液的合成、电导率提高方法及机理
|
摘要
PEDOT/PSS电导率通常小于1 S/cm,较低的电导率限制了其在电化学器件中的广泛应用。PEDOT/PSS膜电导率的提升成为其广泛应用的重要前提。综述了PEDOT/PSS水性分散液的合成、PEDOT/PSS膜电导率降低的机理,并介绍了提高PEDOT/PSS膜电导率的方法和相关机制,这对于提升PEDOT/PSS的应用范围和空间具有重要的意义。
The conductivity PEDOT/PSS is usually less than 1 S/cm,which badly affects its extensive applications in electrochemical devices.To enhance the conductivity of PEDOT/PSS is necessary for its wide applications.Synthesis of PEDOT/PSS aqueous solution and mechanism of its low conductivity are introduced.The methods to improve its conductivity and corresponding mechanism are also summarized,which is significant to its wide applications in broader areas.
