Preparation and Morphological Study of Biphasic Janus Microparticles andMicrofibers

The electrohydrodynamic co-jetting process can be used to produce both particles throughelectrospraying and fibers through electrospinning. In this research, by adjusting the viscosity of thepolyethersulfone solution in dimethylformamide and also the electric potential applied to the nozzle,biphasic Janus particles and fibers were produced owing to the formation of a stable Taylor cone asa result of a balanced electrostatic tension and surface tension. The confocal laser scanningmicroscopy revealed the successful formation of biphasic dumbbell-like particles made of twospherical particles about ۱.۸ μm in diameter and fibers ۹۳۳ nm in diameter. This technologicaladvancement holds great promise for the preparation of various Janus architectures for diverseapplications, ranging from drug delivery to industrial processes.
