AB - In this study, a comprehensive experimental design was employed to  investigate the impact of four key factors on the spinning of polylactic  acid (PLA) nanofibers. The four factors, namely the solute concentration of  PLA, the solvent ratio, the spinning voltage, and the spinning receiving  distance, were meticulously optimized through an L9(34) orthogonal  experiment. The determination of the optimal process parameters for the  preparation of PLA porous nanofiber membranes was achieved through the  utilization of SEM and the analysis of fiber diameter data. The polymeric  liquid adhesive was concentrated to 8 wt.%, the solvent ratio (DCM:DMF) was  set at 9:1, the spinning voltage was set at 20 kV, and the spinning distance  was set at 18 cm. In light of these findings, a series of PLA/GO porous  nanofiber membranes with varying concentrations of graphene oxide (GO) were  meticulously prepared. The study examined the impact of different GO  contents on the proper-ties of the fibers. The experimental approach  entailed the assessment of several parameters, including surface energy  measurement and thermogravimetric analysis. The results demonstrated that  when the GO concentration was set at 0.5 wt.%, the PLA/GO porous nanofiber  membrane with uniform diameter distribution.
