Dielectric properties of composite LaMnO3 nanofiber by electrospinning technique

Electrospinning technique has been extensively developed as a simple and vasatile method for drawing nanofibers from polymer solutions. Lanthanum Maganite La1-x MnxO3 (x = 0.02 mol) nanofibers were obtained by calcinations of PVA/LaMnO3 composite at different temperatures with electrospinning utilizing sol-gel precursors. Novel polycrystalline LaMnO3 nanofibers were yielded at 500 °C, 600 °C and 700 °C for 2 h as the final products. Field Emission Scanning Electron Microscopy (FESEM) was employed to study the fiber diameter of samples. The average diameter of the LaMnO3 nanofibers was found to be in the range of 85 nm to 150 nm at different temperatures. The dielectric properties of LaMnO3 nanofibers were identified by C-f, r-f, tan - f and ac-f characteristics. The results obtained from this research will lead to enable new levels of electronic applications, biomedical applications and protective clothing
