Superhydrophobic polysilsesquioxane/polystyrene microspheres with controllable morphology: from raspberry-like to flower-like structure

Abstract

Superhydrophobic polysilsesquioxane/polystyrene micro-spheres with raspberry- to flower-like structure were fabricated via a CTAB-assisted sol–gel approach.

Recent Progress in Preparation and Anti-Icing Applications of Superhydrophobic Coatings

“…Lu et al prepared superhydrophobic SiO 2 films on the surface of aluminum alloy by the pulling method [112], where SiO 2 nanoparticles were added into a mixture of C 2 H 12 N 4 and Zn(NO 3 ) 2 •6H 2 O to prepare sol. Dong and Ha fabricated superhydrophobic polysilsesquioxane/polystyrene microspheres with flower-like structures via a cetyltrimethyl ammonium bromide-assisted sol-gel approach [113]. The structure produced by nanoparticles on microcores could be controlled from raspberry-to flower-like morphology precisely through adjusting the content of silane precursor.…”

Shape engineering of polystyrene particles from spherical to raspberry-like to hollow flower-like via one-step non-surfactant self-templating polymerization of styrene in ethanol–water mixtures

“…Synthesis of asymmetric non-spherical nanomaterials with controllable morphologies has become a hot topic of research. 1 Non-spherical morphologies endow materials with enhanced physical and chemical properties, such as mechanical strength, thermal stability, good adsorptivity, catalytic activity, 2 and rheological properties. 3 To date, PS particles with different nonspherical shapes, such as bowl-like, 4 raspberry-like, 5 owerlike, 2 peanut-like, 6 snowman-like, and triple rod particles 7 have been synthesized.…”

“…15 Dong et al transformed the microspheres from raspberry-like to ower-like morphology by simply adjusting the stoichiometry of the silane precursor. 17 Uniformly-sized hierarchical spheres could be obtained by these methods. And nowadays, a kind of ternary system such as monomer/water/methanol system has been used in polymer latex preparation.…”

Preparation of morphology-controllable PGMA-DVB microspheres by introducing Span 80 into seed emulsion polymerization

“…These porous particles with large surface area have the ability to uptake various solvents with different polarity, and have been widely used in drug delivery, chromatography and molecular imprinting. [3][4][5][6][7][8][9][10][11] Hollow particles with a hollow structure and high loading capacity are usually used in controlled drug delivery, cell sorting and catalysis. [12][13][14] The polymer microspheres are mainly prepared by heterogeneous polymerizations due to the sphere with the lowest surface to volume ratio in the heterogeneous system.…”
