The use of single particles as building
blocks for the design and construction of advanced materials is generally
recognized as a promising approach. This paper reports a novel double-speed
swelling (DSS) technique to fabricate solid–liquid asymmetric
monomer-swollen particles (MSPs) with adjustable and removable liquid
protrusions on the surface of non-cross-linked poly(glycidyl methacrylate)
(PGMA) colloidal particles, although this procedure is thermodynamically
unfavorable. Further, PGMA/polystyrene (PS) patchy microparticles
with controllable morphologies are fabricated by a versatile and large-scale
seeded emulsion polymerization (SEP) on the basis of these MSPs. The
size and number of protrusions can be precisely regulated by the swelling
ratio and the amount of polymerizable monomer. These patchy microparticles
exhibit excellent light reflection and could be applied as new thermal
barrier coatings. Additionally, the self-assembled “particle
gel” membranes with superoleophilic properties have been employed
to absorb model oil and exhibited efficient absorption performance.
