Preparation of hollow poly (styrene-co-divinylbenzene) particles with variable cavity sizes and further fabrication of hollow TiO2 particles using solid poly (styrene-co-divinylbenzene) particles as templates

Morphology control and 2D self-assembly of poly(styrene-co-divinylbenzene) capsules

“…1. Compared with the mushroom cap-like PS-DVB capsules obtained in our previous work [41], in which the content of DVB was 20 wt.%, capsules show bowl-shaped morphology here when the content of DVB decreased below 13-10 wt.%. In Fig.…”

“…When the cross-linking degree of DVB in PS-DVB microcapsule decreased from 20 wt.% [41] to 18 wt.%, the spherical PS-DVB capsules were deformed into bi-caved, tri-caved, and tetra-caved shape (Fig. 5), not mushroom cap-like or bowl-like shape any more.…”

“…The capsules size distribution (Fig. S3) showed that the mean diameter of PS-DVB capsules containing 10 wt.% DVB was 420 nm, which is a little bigger than that of core-shell particles [41] for the reason of acetone swelling effect. This proved that the capsules were still spherical even after being etched the core by CCl 4 and dispersed in acetone.…”

“…Firstly, we prepared monodisperse, sub-micrometer-sized poly(styrene-co-divinylbenzene) (PS-DVB) particles according to our previous work [41]. The shell thickness was controlled by judiciously adjusting the content of cross-linking agent DVB in the polymerization process, while the diameter of the copolymer spheres almost stayed invariable.…”

Synthesis, growth mechanism and optical characterization of zinc nitride hollow structures

“…Recently micro to nano-scaled hollow structures such as hollow spheres, hollow needles, hollow capsules, hollow particles, hollow fibers, hollow cube and hollow plates, etc have attracted much interest from the researchers owing to their unique physical and chemical properties like light weight, low density, thin walls, large fraction of surface area, toughness, flexibility, ionic conductivity, enhanced chemical activity and electrical properties [1][2][3][4][5][6][7][8]. These novel hollow structured materials have enormous potential applications such as pharmaceutics, agricultures, cosmetics, artificial cells, photonic crystals, catalysts, fillers, coatings, removal of pollutants, confined reaction vessels, battery materials, pigments, protection of light-sensitive components, controlled release of drugs and gas sensing devices [9][10][11][12][13][14][15].…”
