Synthesis of Barium ferrite via Citric Glycerol Sol-Gel Method for Magnetic-Polylactic acid Fibers

Abstract

Barium ferrite (BaFe₁₂O₁₉) powders were successfully synthesized by citric glycerol sol-gel method using glycerol incorporating with citric acid to form organic network. The obtained barium ferrite powder and polylactic acid (PLA) were mixed to prepare a masterbatch by using twin screw extruder. Various amounts of masterbatch (0-15 phr) were mixed with PLA to form magnetic-PLA fibers by using melt-spinning technique. The obtained fibers were characterized by using FTIR, DSC, XRD, UTM and SEM while the magnetic property was studied by VSM.
