New Insights into RAFT Dispersion Polymerization‐Induced Self‐Assembly: From Monomer Library, Morphological Control, and Stability to Driving Forces

“…As can be easily imagined, the structure of the cationic moiety can be adjusted as well. Similarly, ionic liquid monomers based on N ‐vinyl‐3‐alkylimidazolium bromide with tunable length of the alkyl groups suitable for aqueous dispersion polymerization were also reported . Interestingly, rigid rods over a wide range of composition were obtained even at low solids via aqueous polymerization of N ‐vinyl‐3‐dodecyl imidazolium bromide (C 12 VImBr) mediated by a neutral PEG‐CTA .…”

Interplay of Solvation and Size Effects Induced by the Counterions in Ionic Block Copolymers on the Basis of Hofmeister Series

“…For example, Clˉ and Brˉ counterions are considered as highly ionized ions for fixed polycations, while PF 6ˉ and bis(trifluoromethane)-sulfonimide (ˉNTf 2 ) are able to form tight ion pairs and turn cationic blocks insoluble in water but soluble in common organic solvents. [37][38][39][40][41][42] On the basis of this factor, the morphological structures of cation-containing polymers could be manipulated by simple anion exchange, which results from the tunable solubility of the ionic blocks. [43][44][45][46][47][48][49][50][51] For example, Vijayakrishna and co-workers found that the morphology of aggregates could be altered by exchanging of ˉN(SO 2 CF 3 ) 2 for Brˉ in imidazoliumbased ionic blocks.…”

Photopolymerization of Ionic Liquids – A Mutually Beneficial Approach for Materials Fabrication

“…[34] While there are some examples for the polymerization of cationic vinyl monomers since 1970s, [35,36] it was only around the year 2000, pioneered by Ohno et al, that vinylimidazolium and vinylpyridinium salts were pursued as monomers for the creation of solid polymer electrolytes. [37][38][39] Since then, polymeric ionic liquids have become ubiquitous in the literature with research led by Long, [40][41][42][43] Texter, [44,45] Yuan, [46][47][48] Merceyyes, [30,49,50] Shaplov, [51][52][53][54][55] Drockenmuller, [56][57][58] and others to name a few. [59,60] The improved processability of polymers combined with the chemical utility and derivatizability of ionic liquids is the cornerstone for their interest and broader use.…”
