Abstract

Abstract: Aluminum particles have been used as an additive of high density and energy to improve the energy of fuel and propellant. Here the possibility of preparing suspension fuel was studied by modifying the surface of Al nanoparticles (NPs) and adding them into liquid fuel. Trioctylphosphine oxide (TOPO) was used as the surfactant to modify the NP surface，and the particle structure and dispersion stability，as well as the density，energy and viscosity of suspension fuel were analyzed. It is found that the surface modification could inhibit the agglomeration and settlement of NPs，and made them disperse stably in liquid hydrocarbon fuel like HD-03 for a relatively long time. The density and volumetric energy of the fuel increased significantly，and it could flow freely like common liquid fuel. With 10wt% and 30wt% NPs added，the density，volumetric energy and viscosity of the fuel were 1.06g/mL and 1.14g/mL，44.3MJ/L and 45.4MJ/L，80mPa·s and 2000mPa·s，respectively.

摘要： 铝颗粒是一种高密度高能量的燃料添加剂，研究了一条通过表面改性使纳米铝颗粒分散在液体碳氢燃料中，进而制备高密度悬浮燃料的路线。采用三正辛基氧膦对铝颗粒进行表面改性，表征了改性颗粒的结构和在燃料中的分散稳定性，测试了悬浮燃料的密度、能量和粘度。结果表明，表面改性能够阻止铝颗粒的团聚和沉降，使其较长时间内稳定分散在高密度燃料HD-03中；含有铝颗粒的悬浮燃料的密度和体积热值显著提高，保持液体状态和良好流动性。其中，含有10wt%和30wt%铝颗粒时的燃料密度分别为1.06g/mL，1.14g/mL，体积能量分别为44.3MJ/L，45.4MJ/L，动力粘度分别为80mPa·s，2000mPa·s。
