Morphology control of shell-crosslinked polymer particles prepared by photo-induced shell-selective crosslinking approach via dispersed state control

摘要

Hypothesis: Morphology control of polymer particles is of great importance for creating functional particulate materials. Photoinduced shell-selective crosslinking approach with spherical polymer particles has been previously developed in a dispersed state, in which the polymer particles could rotate freely, yielding hollow polymer particles after removal of non-crosslinked polymers because photoinduced crosslinking occurred for the entire particle surface. This insight prompted the question of whether non-spherical particles can be obtained if particle rotation is restricted and photoirradiation occurs for only part of the shell region.
