Abstract

A new surface pore-forming technique based on the traditional breath figure (BF) method was introduced. By performing such direct pore-forming breath figure technique, porous structure was successfully fabricated on the surface of polymeric microspheres. Facile pore formation on the surface of micro-sized three-dimensional objects was proved to be feasible by reforming the way BF method was performed. Specifically, uniform-sized microspheres of polystyrene (PS) were prepared by microfluidic method, and the "golf ball-like" PS microspheres with porous surface pattern were obtained by applying direct pore-forming breath figure technique with solvents under humid conditions. The pore-forming conditions of microspheres were systematically studied by adjusting the choice of solvents, the applied amount of solvents and the humidity. The direct pore-forming breath figure technique may span the range of geometric limitation on the BF substrate/object.
