Abstract

Barium titanate (BaTiO₃) containing polypropylene (PP) composite filaments were melt spun to modify polymer electrostatic charging characteristics. Sample filaments were charged with a corona instrument and their surface potentials were measured. Initial surface potential as well as potential stability was monitored through an accelerated decay procedure. It was found that both BaTiO₃ concentration and charging temperature influence the charging characteristics of the fibers. When BaTiO₃/PP composite filaments were charged at 130 °C, significant enhancements were observed when compared to samples charged at room temperature. The distribution of BaTiO₃ particles within the filaments and changes in the crystal structure were also examined.
