Abstract
In this study, a new method for producing fibers with hybrid organic–inorganic perovskite (HOIP) cores and hydrophobic polystyrene shells via coaxial electrospinning is introduced. The presence of the HOIP, CH3NH3PbI3, was verified through the use of ultraviolet to visible spectroscopy and x-ray diffractography to confirm successful synthesis in situ. Morphologies of the coaxial fibers were investigated using scanning electron microscopy to confirm the core/shell geometry and assess the fiber diameter. Finally, the interaction of liquid water and the fiber mats was studied to assess improvements to moisture resistance garnered from encapsulation in coaxial electrospun fibers.
