Complex interactions in aqueous PIL-PNIPAm-PIL triblock copolymer solutions

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.…”

Polymerized ionic liquid block copolymers for electrochemical energy

“…[43][44][45][46][47] Segalman and coworkers 43 synthesized poly(styrene-b-histamine methacrylamide) (PS-b-PHMA) diblock copolymers via ATRP using the activated ester strategy, followed by post-functionalization with triuoroacetic acid (TFA) resulting in the protic diblock copolymer, PS-b-PIL (see structure in Table 1). [43][44][45][46][47] Segalman and coworkers 43 synthesized poly(styrene-b-histamine methacrylamide) (PS-b-PHMA) diblock copolymers via ATRP using the activated ester strategy, followed by post-functionalization with triuoroacetic acid (TFA) resulting in the protic diblock copolymer, PS-b-PIL (see structure in Table 1).…”

“…Within these techniques, generally two overarching strategies have been used to produce PIL block copolymers: the sequential polymerization of multiple non-ionic monomers followed by subsequent functionalization or quaternization of one of the monomers 11,12,14,27,[30][31][32][33][34]42,43 and the direct sequential polymerization of a non-ionic monomer and an IL monomer. 13,[15][16][17][18][19][20][21][22][23][24][25][26]28,29,[35][36][37][38][39][40][41][44][45][46][47] The former allows for facile molecular weight determination of the non-ionic precursor block copolymer with conventional techniques, such as gel permeation chromatography (GPC). The latter requires the addition of salt to minimize the aggregation of the charged polymer in solution when using techniques such as GPC.…”

“…Atom transfer radical polymerization (ATRP) is another relatively popular route to produce PIL block copolymers. [43][44][45][46][47] Segalman and coworkers 43 synthesized poly(styrene-b-histamine methacrylamide) (PS-b-PHMA) diblock copolymers via ATRP using the activated ester strategy, followed by post-functionalization with triuoroacetic acid (TFA) resulting in the protic diblock copolymer, PS-b-PIL (see structure in Table 1). More recently, ATRP was utilized by Matyjaszewski and coworkers 46 to produce ABA PIL triblock copolymers with either polyketone (PEEK) or polysulfone (PAES) center blocks and butylimidazolium-containing PIL outer blocks.…”

“…Table 1 lists various controlled polymerization techniques (e.g., NMP, RAFT, anionic, CMRP, ROMP, ATRP) that have recently been explored to prepare PIL block copolymers. 13,[15][16][17][18][19][20][21][22][23][24][25][26]28,29,[35][36][37][38][39][40][41][44][45][46][47] The former allows for facile molecular weight determination of the non-ionic precursor block copolymer with conventional techniques, such as gel permeation chromatography (GPC). 13,[15][16][17][18][19][20][21][22][23][24][25][26]28,29,[35][36][37][38][39][40][41]…”
