    摘要:

    为了改善高密度碳氢燃料——挂式-四氢双环戊二烯(JP-10)的燃烧性能,制备了超支化聚缩水甘油(HPG)、超支化聚乙烯亚胺(HPEI)稳定的JP-10基铂纳米流体燃料。用相转移法合成亲油性铂纳米颗粒Pt@HPG和Pt@HPEI,通过透射电子显微镜(TEM)、X射线光电子能谱(XPS)、X射线衍射(XRD)和热重分析(TG)进行结构和性能表征,Pt@HPG和Pt@HPEI平均粒径分别为1.3 nm和2.4 nm。纳米流体Pt@HPG/JP-10与JP-10间无明显的密度、黏度差异;Pt@HPEI/JP-10与JP-10间无明显的密度差异,而黏度下降较为明显,可一定程度降低输运流阻。采用氧弹燃烧法评价氧压0.6 MPa与0.8 MPa条件下纳米流体的燃烧性能,与基液JP-10相比,纳米流体的表观燃烧热可明显增加,Pt@HPG/JP-10和Pt@HPEI/JP-10分别增加了约7.8%和7.6%。超支化聚合物稳定的JP-10基铂纳米流体有望成为有应用潜力的新型高能燃料。

    Abstract:

    In order to enhance the combustion performance of high-density hydrocarbon fuel exo-tetrahydrodicyclopentadiene (JP-10), JP-10 based Pt nanofluid fuels stabilized by oil soluble hyperbranched polyglycerol (HPG) and hyperbranched polyethyleneimine (HPEI) were designed and synthesized. Fuel-dispersible Pt nanoparticles Pt@HPG and Pt@HPEI were synthesized through the phase-transfer method and characterized by transmission electron microscopy (TEM), X-ray photoelectron spectrometry (XPS), X-ray diffraction (XRD) and thermogravimetric analysis (TG). The average sizes of Pt@HPG and Pt@HPEI were 1.3 nm and 2.4 nm. There were slight differences in density and viscosity between Pt@HPG/JP-10 and JP-10. Compared to JP-10, Pt@HPEI/JP-10 had no significant difference in density, while the viscosity decreased obviously, which can reduce the flow resistance. Oxygen bomb calorimetric experiments were carried out to investigate the combustion performance of nanofluids Pt@HPG/JP-10 and Pt@HPEI/JP-10. The apparent values of combustion heat of various nanofluids increased markedly in comparison with that of JP-10. The apparent combustion heat of Pt@HPG/JP-10 and Pt@HPEI/JP-10 increased by about 7.8% and 7.6%, respectively. JP-10 based Pt nanofluids stabilized by hyperbranched polymers are supposed to be novel kinds of potential high-energy fuels.
