Investigating the effect of electrolyte types with various ionic liquids on the electrochromic performance of PEDOT: PSS based LbL multilayers. Microelectronic Engineering, 234, 111454.0167-93171873-5568https://doi.org/10.1016/j.mee.2020.111454https://hdl.handle.net/11491/7175The objective of the study is to investigate the electrochromic performances of layer-by-layer (LbL) multilayered thin film electrode prepared from linear polyethylene imine (LPEI) and poly(3,4-ethylenediox-ythiophene):polystyrene sulfonate (PEDOT:PSS) on PET-ITO substrate in the presence of different types of electrolytes. For this purpose, the electrochromic behaviors of (LPEI/PEDOT:PSS) 10 is performed in LiClO4/propylene carbonate (PC) and two different ionic liquids (IL) namely N-methylimidazolium tetrafluoroborate (Melm-BF4) and 2-hydroxy ethyl ammonium formate (2-HEAF), as a function of IL content and scanning rate. The optical contrast value of (LPEI/PEDOT:PSS) 10 film is determined as 58.4% in the existence of 10 wt% of 2-HEAF as the electrolyte. The coloration efficiency of this film is determined as 606.7 cm(2)/C, which this value was greater approximately four times than 1 M LiClO4/PC. According to the obtained results, 2-HEAF has been evaluated as a suitable electrolyte alternative for (LPEI/PEDOT:PSS) 10 film due to its better optical contrast and coloration efficiency compared to other electrolytes.eninfo:eu-repo/semantics/closedAccessElectrochromismPEDOT:PSSLbL Technique2-hydroxy Ethyl Ammonium FormatePET-ITOArticle23410.1016/j.mee.2020.111454Q2WOS:0005821165000072-s2.0-85092488443Q2
