TL;DR: In this article, a phase inverse method was used to make a hybrid polymer membrane, which consisted of poly(vinylidene-fluoride-co-hexafluoropropylene) (PVdF-HFP), polyethylene oxide (P123), ethylene carbonate (EC), propylene carbonates (PC), and LiClO4.

TL;DR: In this article, the relaxation dynamics in miscible blends of PEO and PMMA ranging in composition from 20 to 60 wt% of PMMA were studied subsequent to a linear step strain using the simultaneous measurement of infrared dichroism and birefringence.
Abstract: Relaxation dynamics in miscible blends of PEO and PMMA ranging in composition from 20 to 60 wt% of PMMA are studied subsequent to a linear step strain using the simultaneous measurement of infrared dichroism and birefringence. From the temperature and composition dependences of component relaxation times it is clear that each component of the blend retains a separate rheological identity. Component relaxation dynamics shows a dramatic and complex sensitivity to blend composition. In PMMA-rich blends each component adopts a separate friction factor with a unique temperature dependence

TL;DR: A series of six conjugated aromatic polyazomethines has been obtained by high-temperature solution polycondensation of diformyltriphenylamine with different primary aromatic diamines as mentioned in this paper.
Abstract: A series of six conjugated aromatic polyazomethines has been obtained by high-temperature solution polycondensation of diformyltriphenylamine with different primary aromatic diamines. The structures of polymers are characterized by means FTIR, 1H NMR, and 13C NMR spectroscopy and elemental analysis; the results show an agreement with the proposed structure. Polyazomethines emitted blue or blue-green light. Relative PL intensity of the polymers investigated in chloroform solution was found about 0.30%, while for doped ones it was about 20% in relation to 9,10-diphenylanthracene. Additionally, the photoluminescence spectra of the polyazomethines in polymer blend with poly(methyl methacrylate) (PMMA) have also been described. The lowest optical band gap value at 2.41 eV was detected. Polymers were investigated also by cyclic voltametry and differential pulse voltammetry in dichloromethane. An influence of different types of dopants, i.e., methanesulfonic acid (MSA), camphorsulfonic acid (CSA), m-cresol (MC),...
