Polymers, acrylate-based amphiphilic

Perfluoroalkyl groups are also introduced into block copolymers with methacrylates, acrylates, and styrene (B-46 to B-53), which can be synthesized in scCC>2 or in the bulk.95,315 Amphiphilic block copolymers based on glycopolymer segments (B-54 and B-55) are synthesized by copper-catalyzed polymerizations.321,322 Comonomers with a polyhedral oligomeric silsesquioxane unit afforded hybrid polymers between organic and inorganic components (B-56 and B-57).326... 

Three-layered nanoparticles containing an hbPG core and cross-linked block copolymers based on N-isopropyl acrylate and N,N-dimethylaminoethyl acrylate as the respective arms were synthesized and proved to be thermoresponsive. ° Chu and co-workers" reported electrically conductive core-shell nanoparticles based on poly(n-butylacrylate-b-polystyrene) multiarm star polymers. The PS segments were converted to poly(p-styrenesulfonate) (PSS), thus generating amphiphilic tmimolecular micelles. Then the oxidative propagation of 3,4-ethylenedioxythiophene (EDOT) on the PSS chains was carried out by counterion-induced polymerization to produce a stable aqueous dispersion of the respective PEDOT complex. 

Li et al. (2008a) introduced solvent-resistant multifunctional PV membranes based on segmented polymer networks (SPNs). Hydrophilic (acrylate)-terminated poly(ethylene oxide) was used as a macromolecular cross-linker of different hydro-phobic polyacrylates for the synthesis of amphiphilic SPNs. Multifunctional canposite membranes with thin SPN top layers were prepared by in situ polymerization. The support consisted of hydrolyzed PAN. These membranes were tested for dehydration of EtOH and isopropyl alcohol. The selectivity of the membranes greatly depended on the composition or the ratio of the hydrophilic and hydrophobic phases of the SPN. 

Block copolymers in solution can be self-assembled into a variety of architectures. Micelles are common self-assembled stmctures formed by block copolymers when dissolved in a selective solvent , which is a good solvent for one of the polymer blocks but a poor solvent for the blocks of the other polymer. Binding one of the copolymer blocks with inorganic moieties leads to the formation of nucelles. The inorganic moieties are localized within the core of the micelles and coated with a thin shell of the other copolymer blocks. For example, Taton s group prepared a unidirectional structure of hybrid nucelles based on amphiphilic polystyrene-Wock-poly(acrylic acid) (PS-h-PAA) and gold nanoparticles (AuNPs) (Fig. 1) [25]. 

While the stabilization of W/C microemulsions with Krytox-type polymers or molecular surfactants has been largely reported [66, 67], examples implying amphiphilic copolymers are scarce in literature. These examples—described below— are exclusively based on fluorinated poly((meth)acrylates) as a consequence of their lower surface tension compared to hydrocarbons and poly(siloxanes).
