Synthetic Strategies for Polymer Particles with Surface Concavities

“…This is different to the above-mentioned one-step polymerization methods, in which the surface concavity is formed directly in the polymerization process. Both hard templates [140][141][142][143][144][145][146][147][148][149][150][151][152][153][154][155][156][157] and soft templates [158][159][160][161][162][163][164][165][166] have been used for the preparation of dimpled polymer particles.…”

“…It is worth emphasizing that dimpled polymer capsules can be conveniently fabricated by the "collapse" of the spherical capsules, which are formed by removing the core templates from the core-shell particles. [152][153][154][155][156][157] For example, Zhou and co-workers reported that polydopamine (PDA) nano/microcapsules could be readily produced by the formation of PDA on the template surface, followed by removal of the template. [152] When the diameter of the capsule reached to 2 mm, bowl-like capsules were observed due to collapse.…”

“…A wide variety of post‐treatment techniques, including solvent‐absorbing/releasing, [ 109,110 ] general solvent evaporation, [ 111–121 ] microfluidic emulsification/emulsion–solvent evaporation, [ 122–128 ] electrospraying/solvent evaporation, [ 129–137 ] electrospinning/solvent evaporation, [ 138,139 ] templating method, [ 140–166 ] treatment on core–shell particles [ 167–173 ] and self‐assembly of polymer [ 174–176 ] have been developed for dimpled polymer particles syntheses.…”

Light-Responsive Crosslinked Polymer Particles from Heterogeneous Polymerization of an Asymmetric Divinyl Azobenzene Monomer

“…Such bipolar configuration has been observed in spherical liquid crystalline polymer particles 29,30 and nonspherical particles derived from spherical particles using liquid crystal templates 31 or seeded particles. 32 The preparation of oblate polymer particles generally requires multistep procedures such as the mechanical squeezing or stretching of spherical particles. 34,39 In contrast, the direct preparation of nonspherical polymer particles by the heterogeneous polymerization of a single monomer has been rarely reported.…”

Building permanently optically active particles from an absolutely achiral polymer

“…1d) was identified under the crossed nicols. 42 The bright-field spots gradually disappeared with increasing contents of hydroxyl groups (see Fig. S8 †).…”
