Li+ doped chitosan-based solid polymer electrolyte incorporated with PEDOT:PSS for electrochromic device

Abstract

In this study, solid polymer electrolyte-based on chitosan was prepared with addition of PEDOT:PSS, lithium trifluoromethane sulfonate, propylene carbonate by solvent casting technique. The chitosan-based polymer electrolytes without PEDOT:PSS, with PEDOT:PSS were characterized using electrochemical impedance spectroscopy. The ionic conductivity value was calculated as 4.2 x 10-4 S/cm for the chitosan-based electrolyte including PEDOT:PSS. The SPE having good ionic conductivity was used to fabricate electrochromic device with glass/ITO/WO3|PEDOT:PSS-Ch-LiTRIF-PC|ITO/glass whose performance was evaluated via cyclic voltammetry, transmittance, and repeating chronoamperometry. The optical contrast of ECD was attained as 22% at 800 nm, resulting in a coloration efficiency of 67 cm 2 /C. The ECD displays fast response time for coloration (tc), which is 0.29 s. Upon reversal of potential bleaching (tb) forms within 3 s. The findings demonstrated that this SPE electrolyte has promising candidate for use in optoelectronic applications.

Bankanın Mevduat Hesabı Üzerinde Takas veya Mahsup Yetkisi

“…Doktrinde yabancı paranın aynen ödenmesi şart olduğundan, taraflar aksini kararlaştırmadıkça, TL cinsinden bir borçla takas edilmesinin mümkün olmadığı ifade edilmektedir 112 . Diğer yandan aynen ödeme kaydını içeren yabancı para borcu ile TL borcunun takas edilip edilemeyeceği tartışmalıdır 113 . Burada banka ile mevduat sahibi arasındaki sözleşmede aynen ödeme kaydına yer verilmişse, yabancı para borcunun TL borcu ile takas edilememesi gerekmektedir 114 .…”

Effect of hBN on Response Times of PEO-Based Electrochromic Devices

“…The device is protected by coating transparent conductive electrodes on plastic and glass surfaces. Ions are transferred between the ion storage and electrochromic layers through the electrolyte layer (Fu, 2010;Eren, 2018). The electroyte layer, small ions such as protons H + or lithium ions Li + , rarely Na + and Ag + , are used (Eren, 2018;Solovyev et al, 2016).…”

Optical, morphological and photocatalytic properties of biobased tractable films of chitosan/donor-acceptor polymer blends

“…Overall, the use of biopolymers in the preparation and characterization of different types of nanocomposite films is considered to be an innovative strategy for minimizing potentially negative environmental impacts (Roy et al, 2020;Yang, Dahlström, Edlund, Lindman, & Norgren, 2019). For example, the preparation and characterization of films constituted of chitosan and donor (or acceptor) materials (e.g., graphene, polyelectrolytes) have been reported by other authors for potential technological applications (e.g., gas transport, filtration, anticorrosion, biomedical, fuel cell, solar cells, batteries, sensors and supercapacitors) (Ahmed, Mulla, & Arfat, 2017;Eren, 2019;Yang, Liu, Kong, Kang, & Ran, 2019;Yu et al, 2020;Zainudin et al, 2018;Zolfagharian, Kaynak, Khoo, & Kouzani, 2018). However, due to the different hydrophobic/ hydrophilic characters of a blend`s component materials, immiscibility issues, regardless of the composition and nature of the polymers, can arise (Bonardd et al, 2020;Méndez-López et al, 2018).…”
