چکیده    Electrospun nanofibers (enfs) were fabricated from the mixture of cellulose acetate (ca), chitosan (chi), and poly (ethylene oxide) using an acetic acid solution. the impact of ca/chi ratio (0.5, 1, 1.5 wt %), chi/peo ratio (1, 1.5, 2 wt%), sodium dodecyl sulfate (sds) (0, 1.5, 3% w/w) and ammonium oxalate (3%, w/w) on the diameter, tensile strength, elongation, and porosity of the enfs were optimized using response surface methodology-central composite rotatable design (rsm-ccrd). the results revealed that enfs were formed of non-woven fibers with a maximum diameter of 113 nm. second-order polynomial models with high r2 values (0.996–0.99) were developed using cubic analysis. the optimum condition was identified to be at the compounded level of ca/chi 1.5 wt%, chi/peo 1 wt%, and sds 3% (w/v). at the best point, the diameter, surface tension, elongation, and porosity of the fabricated enfs were 96.07 nm, 0.054 n/mm2, 13.09 mm, and 52.29 respectively.
