摘要
Abstract
To develop novel active metal complex fuels,three new types of active metal complexes were synthesized using cyano-borohydride(CBH-)as the anion,transition metal Cu(Ⅱ)as the central ion,and 1-methylimidazole(1-MIM),2-methylimidazole(2-MIM)and 4-methylimidazole(4-MIM)as ligands.Their structures were accurately characterized via infrared spectroscopy and single-crystal X-ray diffraction,and the corresponding structural formulas are[Cu(1-MIM)4](CBH)2,[Cu(2-MIM)4](CBH)2 and[Cu(4-MIM)4](CBH)2,respectively.The thermal decomposition properties,energy density and mechanical sensitivity of the three novel metal complexes were tested.Their theoretical specific impulse when combined with 90%H2O2 oxidizer was calculat-ed based on NASA-CEA,and the hypergolic ignition performance of the novel active metal complex fuels with 90%H2O2 was in-vestigated via high-speed photography.The results show that all three metal complexes exhibit high energy density(26.5-27.3 kJ·g-1)and low sensitivity,with friction sensitivity>360 N and impact sensitivity>40 J.All three complexes can undergo hy-pergolic reaction upon contact with 90%H2O2 at room temperature,and the ignition activity follows the order[Cu(2-MIM)4](CBH)2<[Cu(4-MIM)4](CBH)2<[Cu(1-MIM)4](CBH)2.Among them,[Cu(1-MIM)4](CBH)2 has the shortest ignition delay time of 43 ms,indicating that different methyl substitution positions on the ligand significantly affect the hypergolic ignition per-formance of the complexes with 90%H2O2.关键词
