Systematic study on fabrication of hollow poly(vinyl cinnamate) particles by particulate interfacial photocrosslinking

Hollow polymer particles are widely used in various industries as coatings and thermal insulation materials. The encapsulation capabilities of various functional molecules and/or nanomaterials also provide access to applications such as drug delivery, heat storage, and catalysis, as well as self‐healing materials. In this study, we successfully fabricated hollow polymer particles from poly(vinyl cinnamate) (PVC) particles using LED light (λ = 265 nm) through interfacial photocrosslinking. Furthermore, we systematically studied the effect of various parameters (solid contents of parent particles, photoirradiation time, photoirradiation power, and polymer chain length) on the polymer shell thickness of the hollow PVC particles fabricated by interfacial photocrosslinking. These findings are expected to further promote the use of hollow polymer particles in pharmaceutical and material applications.
