Impacts of polymer–polymer interactions and interfaces on the structure and conductivity of PEG-containing polyimides doped with ionic liquid

Promotion of Thermal Imidization of Semi-Aliphatic Polyimide Precursors by Incorporation of Polyethylene Glycol and Their Modified Solid Structures

“…This result coincides well as the previous report [8]. According to the literature [5], enhancement of flexibility in the polymer chain is effective to lower the barrier of the molecular motion which facilitates imidization reaction. Thereby, this promoting effect is attributable to an increase in the molecular motion by PEG additive.…”

“…On the other hand, enhanced molecular motion at elevated temperatures is advantageous for promoting the thermal imidization of PAAs [5]. Thereby, lowering of T g of PAA by introducing flexible linkages in the main chains is promising to enhance φ i at lower temperatures.…”

Enhanced electroluminescent efficiency with ionic liquid doped into PEDOT:PSS hole-injecting layer

“…The electronic characteristics of ILs has a potential to change the electronic performance of PEDOT:PSS. ILs have been extensively applied for the modification of fibrous electrodes for energy applications [24], silica nanocomposite for fuel cell [25], morphology and mesophase formation of electrospun polylactide nanofibers [26], complex interactions in aqueous triblock copolymer solutions [27], structure and conductivity of PEG-containing polyimides [28] and the ordered structure of crystalline polymers [29]. All these results indicated that ILs have a significant impact on the morphological structure and performance of materials.…”

The synthesis of poly(phenylene sulfide sulfone) in ionic liquids at atmospheric pressure

“…6,7 ILs, employed as a novel and environmentally benign solvents, instead of classical organic ones, have attracted much attentions in the elds of chemistry and industry, such as organic synthesis, polymer preparation, and composite membrane preparation and so on. [8][9][10] So far, the traditional free radical polymerization, controlled radical polymerization, polycondensation and ionic polymerization have been carried out successfully in ILs. [11][12][13] Polycondensation in ILs has been well investigated in the past decades.…”
