采用原位聚合法及水热法两步制备碳纳米管@聚苯胺/二硫化钼（C-P-M）和碳纳米管/二硫化钼@聚苯胺（C-M-P）2种复合物。通过改变材料的复合顺序以及钼源的种类来调控复合材料的形貌结构，探究其对电化学性能影响的根本原因，从而达到优化复合材料性能的目的。电化学测试结果表明，C-P-M的电化学储能性能优于C-M-P，并且以（NH₄）₂MoS₄为Mo源合成的三元复合物（C-P-M-2）的性能要优于以Na₂MoO₄·2H₂O为Mo源合成的三元复合物（C-P-M-1）。在电流密度为1 A/g时，C-P-M-2的比电容达到563.7 F/g；在电流密度为10 A/g下经过1 000圈循环稳定性测试，其比电容仍保留为原来的83%。

Carbon nanotube@polyaniline/molybdenum disulfide (C-P-M) and carbon nanotube/molybdenum disulfide@polyaniline (C-M-P) composites are both prepared via in-situ polymerization and hydrothermal methods.The morphology and structure of these composites are controlled by changing the composite sequence and the types of molybdenum sources.The root causes of different effects on electrochemical properties are explored, so as to optimize the performance of composites.Electrochemical tests show that the electrochemical energy storage performance of C-P-M is better than that of C-M-P, and C-P-M-2 ternary composite synthesized with (NH₄)₂MoS₄ as Mo source has a better performance than C-P-M-1 synthesized with Na₂MoO₄·2H₂O as Mo source.At a current density of 1 A·g^-1, the specific capacitance of C-P-M-2 reaches 563.7 F·g^-1.After experiencing 1 000 cycles of stability testing at a current density of 10 A·g^-1, the specific capacitance of C-P-M-2 remains 83% of its initial value.
