The effects of ammonium perchlorate (AP) and graphene oxide (GO) on the curing of glycidyl azide polymer (GAP) were investigated. The rheological parameters of GAP crosslinked by bispropargyl succinate (BPS) were investigated by rheometry instrument. The curing kinetics by the differential isoconversional method revealed that AP (1 wt%) increased the apparent activation energy from 72.98 to 76.41 kJ mol⁻¹. However, the presence of GO (0.1 wt%) catalyzed the curing of GAP/triazole by decreasing the apparent activation energy to 62.86 kJ mol⁻¹. The physical models revealed that the addition of GO changed the cure mechanism of GAP/BPS as it acted as new nucleation sites. The Fourier-transform infrared (FTIR) and X-ray photoelectron (XPS) results also showed that chemical groups on the surface of GO reacted with the hydroxyl groups of GAP, which changed the curing mechanism of GAP/BPS and improved the tension strength of the propellant by 104%.

研究了高氯酸铵（AP）和氧化石墨烯（GO）对缩水甘油叠氮化物聚合物（GAP）固化的影响。用流变仪研究了双炔丙基琥珀酸酯（BPS）交联的GAP的流变参数。通过微分等转化法的固化动力学表明，AP（1wt％）将表观活化能从72.98增加到76.41kJ mol ^-1。但是，GO（0.1 wt％）的存在通过将表观活化能降低到62.86 kJ mol ^-1来催化GAP /三唑的固化。。物理模型表明，GO的添加改变了GAP / BPS的固化机理，因为它充当了新的成核位点。傅立叶变换红外（FTIR）和X射线光电子（XPS）结果还表明，GO表面的化学基团与GAP的羟基发生反应，从而改变了GAP / BPS的固化机理并提高了其抗张强度。推进剂下降了104％。
