Methods For Improving Dispersion of Nanoparticles In Composite Solid Propellants

Usingof nanoparticles in Composite solidpropellant formulations has extended in recent years. Nano additiveshave characteristics as high potential of reactivity, high catalytic activity and high surface area to volume ratio. For this reasons, usingof this additives in Composite solidpropellant formulations increases burning rate ofthemand consequently improvestheirperformance.on the other hand,poor dispersibility ofnanoparticles leads to agglomeration in the binder and thus reduces their effectiveness.To reduce agglomeration and thus, achievingtogood dispersibility of nanoparticles in the binder,drymixing methodisineffective and methods such as premixing, metallic nanooxidesupport,sonication,predispersingand in-situ nano-assembly areeffective.
