Abstract
Despite the plethora of available anisotropic inorganic particles, it remains challenging to fabricate non-spherical polymer particles, especially with angular features. Here we report on the synthesis of monodisperse, flower-like, liquid crystalline (LC) polymer particles by precipitation polymerization of an LC monomer mixture consisting of benzoic acid-functionalized acrylates and disulfide-functionalized diacrylates. Introduction of a minor amount of disulfide-functionalized diacrylates (≤ 10 wt%) induced the formation of flower-like shapes. The shape of the particles can be tuned from flower- to disk-like to spherical by elevating the polymerization temperature. The solvent environment also has a pronounced effect on the particle size. Time-resolved TEM reveals that the final particle morphology was formed in the early stages of the polymerization and that subsequent polymerization resulted in continued particle growth without affecting the morphology. Finally, the degradation of the particles under reducing conditions was much faster for flower-like particles than for spherical particles, a result of their higher surface-to-volume ratio. This work introduces a facile and scalable preparation of non-spherical anisotropic organic particles which may lead to potential applications ranging from smart coatings to redox responsive carrier systems..
