Effect of Processing Parameters on The Electrospinning of Poly(Lactic Acid) /Cellulose Acetate Fibers for Air Filtration Application

Abstract
Polylactic acid (PLA)/cellulose acetate (CA) fibers were fabricated via electrospinning for application in air filtration. The various processing parameters, such as solvent system, polymer solution concentration, and CA content, affecting the morphology and properties of the electrospun fibers were investigated. Mechanical performance, air permeability, and surface morphology of the PLA/CA fibers were investigated. The mixture of dimethylformamide (DMF) and chloroform (CF) solvent enhanced the electrospinnability of the solution due to improved electrical conductivity and viscosity. The addition of CA to PLA significantly affected the nanofiber morphology, yielding finer fibers. Response surface methodology was employed to optimize the electrospinning conditions, with parameters as a feed rate of 1.0 mL/h, an applied voltage of 15 kV, and a PLA:CA weight ratio of 18:10.
