Preparation of aluminum nanoparticles/nitrocellulose nanofibers

In order to overcome the agglomeration of aluminum nanoparticles(AlNPs) in the propellant processing, the smooth and uniform nanofibers of AlNPs/ nitrocellulose(NC) have been successfully fabricated by simple adding AlNPs to NC solution before electrospinning. The effect of electrospinning technique on the morphology and diameter of the nitrocellulose nanofibers were investigated by SEM. The suitable electrospinning conditions were as follows: water content,10% -15% , nitrocellulose solution concentration,5% -10% , voltage, 25 -30 kV and extrusion rate,0. 5 -4 mL/h. The AlNPs/NC nanofibers prepared in the above-mentioned feasible condition reveal that AlNPs distribute uniformly in nanofibers matrix.
