摘要
采用溶剂挥发法,在玻璃基底上制备出具有分形结构特征的RDX晶体,利用扫描电子显微镜(SEM)表征样品的形貌,初步研究了RDX溶液浓度及表面活性剂十六烷基三甲基氯化铵对RDX分形结构的影响,并对RDX分形结构的形成机理进行初步分析。结果表明,借助玻璃基底上的非平衡结晶过程,可实现RDX的多种分形生长;当RDX浓度较低时形成具有明显主干与分枝的分形结构,浓度较高时形成无规分杈的分形结构;表面活性剂对RDX分形结构影响较大。
The RDX with fractal structures was prepared by the evaporation of solvent on glass substrate,and was characterized by scanning electronic microscope（SEM）.The effects of solution concentration of RDX and surfactant on the fractal structure were studied.The formation mechanism for fractal structure of RDX was discussed.Results show that the different fractal structure of RDX can be obtained by means of non-equilibrium crystallization on glass substrate.The dendritic growth of RDX occurs with low concentration of RDX（16 mg·mL-1）,while the random fractal growth occurs with high concentration of RDX（26 mg·mL-1）.The influence of the surfactant of hexadecyl trimethyl ammonium chloride on the morphology of RDX is obviously.
