This research was aimed to study the electrospinning of natural rubber (NR)-acrylonitrile butadiene styrene (ABS) blend. The NR used in this research was compounded in a torque rheometor, with stearic acid, wingstay-L, dibenzothiazoledisulfide (MBTS), tetramethylthiuram disulfide (TMTD) and sulfur, respectively. The compounded NR was blended with ABS by dissolving them in tetrahydrofuran (THF), concentration of solution included 5, 10, and 15 w/w%. The ratio of NR/ABS was varied by varying the content of ABS of 20, 30, 40 and 50 wt%. Then NR/ABS electrospun membrane was built up by electrospinning technique with high voltage 15 kV, flow rate 30 ml/h, collector distance 15, 20 and 25 cm and collected the electrospun fiber on rotating circular at 1000 rpm. The morphology of electrospun fibers were characterized by scanning electron microscope (SEM). SEM images showed that NR/ABS membranes had higher porosity with decreasing ABS contents. Decreasing ABS contents, decreasing solution concentration and increasing collector distance decreased fiber diameter of electrospun NR/ABS.
