The
properties of colloids are considerably affected by particles’
surface morphology. In this work, for understanding the mechanism
of roughness formation in polymeric core–shell (CS) particles,
the surface morphology of synthesized CS particles through seeded
dispersion polymerization (SDP) in the presence of poly(methyl methacrylate)
seeds was investigated. The results revealed that shell polymers with
higher solubility parameters (δ) and glass transition temperatures
(Tg) had a rougher surface. These parameters
directly affect the time needed for chain deformation, which is a
critical parameter in controlling the final morphology. We suggested
a relation based on these parameters to predict the surface morphology
(smoothness or roughness) of CS particles synthesized through SDP
in water.
