A facile random copolymer strategy to achieve highly conductive polymer gel electrolytes for electrochemical applications

Abstract

A facile random copolymer strategy based on poly(styrene-ran-methyl methacrylate) (PS-r-PMMA) is proposed for the preparation of highly conductive and mechanically elastic solid-state gel electrolytes.

Electrochemiluminescence for Characterizing the Polymerization Process during Graphitic Carbon Nitride Synthesis

“…Electrochemiluminescence (ECL) is the process whereby electrogenerated species undergo chemical reaction to form excited state that emits light . ECL is widely used not only in clinical and environmental detection and display filed, but also as an effective tool to analyze the surface state of nanomaterials . Our previous works demonstrate that the ECL intensity and stability of g‐CN nanosheets (CNNS) film is highly dependent on the electron transport efficiency of the film .…”

Asymmetric molecular modification of viologens for highly stable electrochromic devices

“…Electrochemical displays have attracted great attention for use in transparent displays because of their simplicity in device conguration and fabrication process, low-voltage operation, and low-power consumption. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] An example of electrochemical displays is an electrochromic device (ECD) that changes its optical characteristics such as a color through redox reactions of electrochromic (EC) chromophores. The device performance strongly depends on the electrochemical and optical properties of its EC materials.…”

“…22,23 In particular, symmetric viologens bearing two identical alkyl N-substituents have been the most widely used and usually exhibit a blue-colored state. 5,10,22,24 However, there are problems with the practical use of viologens. For example, dialkyl viologen radical cations tend to form dimers via spinpairing when the length of the alkyl chains is sufficiently long (e.g., heptyl) and hydrophilic electrolytes are incorporated.…”

Poly(3,4-ethylenedioxythiophene) Based Solid-State Polymer Supercapacitor with Ionic Liquid Gel Polymer Electrolyte

“…It is the attractive candidate or "green electrolytes" used in energy storage devices. Recently, the development of non-volatile, high-performance GPEs, referred to as ion gels, with various copolymer gelators, including block [23][24][25], random [26,27] and star copolymers have been extensively reported [28]. Among them, 1-butyl-3-methylimidazole tetrafluoroborate (BMIMBF 4 ) has been added into GPE due to its high conductivity, low viscosity, and easy synthesis [18,29], which can effectively improve the characteristics of the solid-state polymer supercapacitor (SSC).…”
