2021年2月1日 · It can be seen that the all four PEC-salt complexes have narrower EW than that of isolated PEC, and the order follows: PEC3-LiBF 4 (6.57 V) > PEC3-LiPF 6 (6.53 V) > PEC3-LiClO 4 (5.92 V) > PEC3-LiTFSI (4.17 V).

2017年11月1日 · Ionized polyelectrolytes in solution can form a complex with oppositely charged polyelectrolytes — a polyelectrolyte complex (PEC). The present article provides a comprehensive review on PECs and their classification, theory and characterization, as well as a critical analysis of the current research.

2022年1月20日 · This critical salt concentration (CSC), or “salt resistance,” has been extensively used to compare the stability and strength of association in PECs. However, the CSC is not always observed, and it shows a strong dependence on the type of ions comprising MA.
2023年4月15日 · Depending on the intended application, the required surface roughness, smoothness and particle size of PECs may differ. For example, thermal processing of PEMUs appeared faster than salt doping; however, AFM characterization revealed a rougher surface in.
2019年3月12日 · The PEC 6 PTMC 4-LiFSI 150 mol% electrolyte demonstrated better Li/electrolyte electrochemical and interfacial stability than that of PEC and PTMC single-polymer electrolytes and maintained a...
2020年4月8日 · Although salt has been highly investigated as an additive over recent decades, the interplay between salt and solvent in PEC materials has received far less attention. In this study, we attempt to fill this gap by exploring how co-solvents (that introduce a hydrophobic constituent) and salinity together can tune the properties of the ...
ABSTRACT: The efect of charge density in blocky and statistical linear polyelectrolytes on polyelectrolyte complex (PEC) properties has been studied with the finding that increased charge density in a polyelectrolyte tends to increase the salt resistance and modulus of a PEC across various polyelectrolyte pairs.
