Fabrication of 3D particle by geometry-mediated mold swelling |
| 초록 |
We report the micromolding technique to create monodisperse polymeric particles with controlled 3D shapes by geometry-mediated tuning of mold swelling and capillarity. A photocurable solution filled in micromolds with varying 2D geometry is spatially transformed into complex 3D shape upon addition of the wetting fluid, by mold swelling and capillarity whose tunability is determined by the mold geometry; The results show that the mold swelling behavior (pattern) is determined by the length of their side, enabling production of non-spherical particles by controlling interfacial deformation. Whereas the tunable capillarity given by mold geometry leads to the directional movement (flow) of the photocurable solution, allowing production of spherical particles with imprinted shapes. Further, we demonstrate fabrication of spherical and non-spherical particles simultaneously using a single mold. |
