Electric‐field‐induced aggregation of polymeric micelles to construct secondary assembly films

Abstract

A new amphiphilic quaternary random ionomer (PIDHES) was used to construct self-assembly films. PIDHES was prepared by a selective ionization of quaternary random copolymer, poly(N,N-domethyl amimethyl methartylate-co-2-hydroxypropyl methacrylate-co-2-ethylhexyl acrylate-co-styrene) precursor, which was synthesized by free radical copolymerization of commercial hydrophilic monomers N, N-domethyl amimethyl methartylate and 2-hydroxypropyl methacrylate and hydrophobic monomers 2-ethylhexyl acrylate and styrene PIDHES could self-assemble into polymer micelles in water, which underwent orientated deposition in the electric field and ultimately produced secondary assembly films. Scanning electron microscopy studies showed that the resultant PIDHES secondary assembly film was smooth and compact. Moreover, it was found that PIDHES micelles concentration and electricfield-induced time had a strong influence on the morphologies of the resultant secondary assembly film.

Polymeric Bowl‐Shaped Nanoparticles: Hollow Structures with a Large Opening on the Surface

“…Although BNPs are not commonly observed in polymer selfassembly compared with micelles or vesicles, amphiphilic polymers with different topological structures including random copolymers, [27,92,93] star polymers, [29,69,94] graft copolymers, [95][96][97] and hyperbranched copolymers [40,98] can also self-assemble into BNPs at specific circumstances. For instance, Eisenberg et al [27] prepared BNPs by the self-assembly of a random copolymer of poly(styrene-co-methacrylic acid) [P(S-co-MAA)].…”
