Abstract Tailoring of physical and chemical properties of material surfaces is important in the fabrication of polymeric materials with complex structure and desired functionalities. One of the efficient routes for surface modification is the incorporation of highly reactive functional groups into polymeric materials, e.g. epoxide in poly(glycidyl methacrylate) (PGMA). However, it often suffers from the damage of the reactive epoxide groups during the process to attain target structures. One simple and efficient way to address this challenge and to successfully achieve complex polymeric structures having reactive groups is electrospinning/spraying technique, which allows to achieve a variety of shapes ranging from colloidal particles to nanofibers with controlled size and morphology to serve the purpose of applications. Using these methods, we have fabricated reactive microparticles and nanofiber mats with poly(styrene-random-glycidyl methacrylate) copolymers. The resulting structures were further functionalized with reactive epoxide groups and different nucleophiles such as alcohol, amine, and thiol. With this strategy, we show the fabrication of Janus fiber mats which has different chemical functionalities on each side and stabilizable microparticles with controlled surface morphologies. These results highlight the possibility of imparting a variety of desired chemical functionalities into the structures of stable organic materials via post-electrospray modification processes.
