In recent years, there has been a growing interest in the formation of copolymer-lipid hybrid self-assemblies, which allow combining and improving main features pure lipid-based copolymer-based systems known for their potential applications biomedical field. As most common method used to obtain giant vesicles is electroformation, so far low Tg polymers flexibility at room temperature. Copolymer...

Abstract Alkyl bromides are used as initiators in most of the atom transfer radical polymerization (ATRP) process and play an important role for controlling ATRP equilibrium. In this work, effect solvent on equilibrium constant ( K ) rate activation k act three isomeric alkyl [namely, N -phenyl(3-bromo-3-methyl)succinimide, -phenyl(3-bromo-4-methyl)succinimide, -phenyl(3-bromomethyl)succinimide...

Abstract Synthetic routes for functionalization of cellulose membranes by polymer chains characterized controlled structures are constantly developed to precisely adjust the properties prepared material while minimizing impact on membrane performance. The review presents a critical and integrative evaluation prior research atom transfer radical polymerization (ATRP) techniques, emphasizing meth...

Abstract Surface molecularly imprinted cellulose‐synthetic hybrid particles are prepared via atom transfer radical polymerization (ATRP). The two‐step process involves the immobilization of α‐bromoisobutyryl bromide in pristine microcrystalline cellulose, to generate ATRP macroinitiator particles, and then creation a crosslinked‐imprinted shell surface considering 4‐vinylpyridine (4VP) ethylene...

Abstract In this study, we show the controlled self-oscillation behavior (i.e., normalized amplitude, swelling rate, and deswelling rate) of self-oscillating gels by introducing grafted chains. The chain was introduced to base gel network “grafting from” method atom-transfer radical polymerization (ATRP). We demonstrated that properties chain, including monomer composition length can lead notab...

Polymers with tailored architectures and degradability were prepared through thiocarbonyl addition ring-opening (TARO) atom-transfer radical polymerization (ATRP) using dibenzo[c,e]oxepin-5(7H)-thione (DOT), Cu(I)Br, tris[2-(dimethylamino)ethyl]amine (Me6TREN) as the thionolactone, catalyst, ligand, respectively, in combination a selection of acrylic comonomers. Although copolymers selectively ...
