Synthesis and characterization of hollow polymer latex particles

The generation of void morphology inside soap-free P(MMA-EA-MAA) particles prepared by seeded emulsion polymerization

“…2, that there were 1-4 voids and a black core inside the anomalous particles, and the size of the core was slightly larger than that of the seed particles used. This special morphology with large pore dimension of several hundred nanometers was obviously different from the morphology of traditional multihollow latex particles reported by Okubo et al [8][9][10][11] and Kan et al [16][17][18], in which many fine pores from several to tens of nanometers inside the particles were observed.…”

Monodisperse Core−Shell Poly(methyl methacrylate) Latex Colloids

“…Also, the size and the properties of the core and the shell as well as the number of shells can be tuned. Our current approach opens up the possibility of preparing hollow cross-linked particles 28 and PMMA particles doped with quantum dots. 29 We are currently working on the development of these systems.…”

Colloidal Nanoreactors and Nanocontainers

“…Since core and shell are, however, frequently chemically rather similar this is another critical step of the preparation procedure. Usually rather aggressive reaction conditions such as prolonged alkali and acid treatment at high temperatures are required to degrade the particle core [78,79]. Although using these methods forms clearly hollow particles, the question remains to what extent the polymer shells survive intact under these conditions.…”
