Electrochromic devices employing methacrylate-based polymer electrolytes

Fast Switching Electrochromic Devices Containing Optimized BEMA/PEGMA Gel Polymer Electrolytes

“…Poly(ethylene glycol) methyl ether methacrylate (PEGMA, Mn = 475, Aldrich) was used as the reactive diluent [11,20]. Bis(trifluoromethane)sulfonamide lithium salt (LiTFSI, CF 3 SO 2 NLiSO 2 CF 3 , battery grade), All the mixtures prepared were later poured on to the electrodes of EC devices and UV irradiated for 3 min under nitrogen atmosphere and these conditions assured a quantitative conversion.…”

“…Liquid electrolytes exhibit low stability, high flammability, and low safety by limiting the possible wide range application of ECDs. To enhance the range of application and also to address the above mentioned problems, solid polymer electrolytes have been suggested as an important ion conducting medium [11]. Actually, polymer electrolytes can guarantee good contact with the electrodes, simple preparation procedures can be adopted, low production cost and good mechanical properties [12] can be obtained along with improved safety, stability and reliability.…”

“…The polymer electrolytes exhibited high ionic conductivity (10 −3 S⋅cm −1 at room temperature) [11,[17][18][19]. Quasi solid state electrochromic devices were successfully realized by using WO 3 and V 2 O 5 films deposited on Indium-doped tin oxide-(ITO) based substrates as electrodes and the optimized BEMA/PEGMA based gel polymer as electrolyte and separator.…”

Synthesis and Characterization of New Copolymer Based Cinnamyl Methacrylate Monomer: Determination of Monomer Reactivity Ratio and Statistical Sequence

“…Poly (Ethyl methacrylate) (PEMA) is methacrylic ester polymer having excellent chemical resistance, high surface resistance and offers high optical transparency 1 . It's widely used because of its great interest in many industrial applications and various fields, such as enhancing of electrical properties of schottky diode and conductivity of batteries 2,3 .…”

Electrodeposition of Insulating Thin Film Polymers from Aliphatic Monomers as Transducers for Biosensor Applications

“…Furthermore, thin coatings at the electrode surface which could occur during a reaction, were neglected for a long time and regarded as a baneful interference hushing a possible insulating polymer up. Electropolymerized thin film polymers possess a wide range of applications in electroanalysis (Kalimuthu et al, 2009), energy storage (Granqvist, 2007), electrocatalysis (Xiao et al, 2009), biosensing (Merkoci, 2009), corrosion protection (Medrano-Vaca et al, 2008), sensors and electronic devices (Liu et al, 2010), electrochromic displays (Reiter et al, 2009), etc. Although polymer films on a surface can be formed in several chemical ways, electropolymerization is one of the most convenient and advantageous especially the thickness control during the film growth.…”
