Monodisperse Anisotropic Microparticles via Single-Hole Swelling PGMA Seed
Particles. Macromolecules, 2015, 48 (20), pp 7592–7603.
Abstract: A
unique phenomenon—a single hole appeared gradually on the surface of the seed
particles and grew with the proceeding of swelling—has been observed during
swelling poly(glycidyl methacrylate) (PGMA) particles. PGMA particles suffer
the function of the swelling agent and styrene monomer and form a single hole
on their surface. SEM and TEM were utilized to observe and demonstrate the
forming process. Inconceivably, monodisperse poly(glycidyl
methacrylate)/polystyrene (PGMA/PS) anisotropic microparticles, including Janus,
raspberry-shaped, acorn-shaped, and hollow with open mouth, have been
fabricated by the seed polymerization of these single-hole microparticles as a
generalized approach. The morphology evolution of PGMA/PS is investigated by
regulating the amount of monomer and monomer/seed weight ratio. Moreover, the
surface of PGMA/PS microparticles are rich in epoxy groups, which has bright
prospects in application in biomacromolecule immobilization and
superhydrophilic/superhydrophobic coating.
