Stretchable polymeric film with enhanced electrical and mechanical properties was written by Sau, Sanjib;Kundu, Sarathi. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Quality Control of 2,2′-Oxybis(ethan-1-ol) This article mentions the following:
Stretchable conducting polymeric films are fabricated by blending poly(vinyl alc.) (PVA) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in presence of polar organic solvents, e.g., DMSO (DMSO) and diethylene glycol (DEG) at different concentrations and their structures and superior properties are explored. X-ray diffraction anal. indicates the emergence of some crystalline domains, which are mostly formed by the PEDOT segments of PEDOT:PSS. Raman spectroscopy reveals the transformation from benzoid to quinoid structure of PEDOT in the presence of DMSO or DEG, which effectively enhances the elec. performance. Nonlinear current – voltage characteristics show that the maximum current is obtained for 7 and 3 wt% DMSO and DEG doped PVA/PEDOT:PSS films resp. and the corresponding current enhancement is around 12 and 38 times in comparison with the untreated film. The charge transport mechanism is illustrated with the Poole – Frenkel effect. FTIR study implies the hydrogen bond formation among PVA, PSS and polar organic solvents that makes the film stretchable. Stress – strain behavior exhibits nearly 2.0-3.0 and 2.5-4.5 times stretchability enhancement for 5 and 7 wt% DMSO and DEG doped films resp. Thus, flexible conducting polymeric films are prepared and their superior elec. and mech. properties for the specific solvent conditions are explored. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Quality Control of 2,2′-Oxybis(ethan-1-ol)).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Quality Control of 2,2′-Oxybis(ethan-1-ol)
