Hexagonal boron nitride filled polymer nanofibers producing and characterization via electrospinning technique

Nanofillers contained polymer fibers have improved mechanical, morphological and thermal properties. In this study, hexagonal boron nitride filled polymer nanofibers were produced from different weight percentages of hexagonal boron nitride mixed TPU-DMF colloid polymer solutions via electrospinning method under fixed electrospinning parameters. Micro structure investigation of hexagonal boron nitride/TPU nanofibers were carried out with Scanning Electron Microscopy (FE-SEM) under the morphological characterization, and determined the nanofibers diameter changes. Thermal characterization of nanofibers was carried out with Differential Scanning Calorimetry (DSC). The morphological characterization of nanofibers shows, diameter values of nanofibers were increased with addition of nanofillers and contrary formation of beads were decreased. Thermal investigation of nanofibers showed, even if melting points of nanofibers were not changed, the enthalpy values were changed depending on filler concentration.
