针对目前纳米材料合成中团聚现象严重的问题，提出了一种新型制备单分散纳米金属氧化物及其多元复合物的制备方法。该方法基于溶胶-凝胶自燃合成纳米材料的研究基础，结合炸药爆炸技术，通过炸药发生热爆炸产生的冲击波使目标产物颗粒进行有效分离，不再形成团聚，目前自定义为凝胶热爆炸方法。本项目拟采用该方法，以NiZn铁氧体和CuO为目标产物，研究凝胶体系中炸药（以RDX为代表）的添加量、添加工艺方法等对热爆炸松团的影响，对比研究凝胶自燃方法与热爆炸方法合成目标物的分散性与性能，探索RDX在凝胶体系形成热爆炸的必要条件，结合数值仿真，提出凝胶体系中炸药多点局部爆炸解团聚机制，为单分散合成提供理论支撑。该方法为纳米材料解团聚方法提供了创新性的思路，对制备其它纳米材料同样具有推广意义。 [ Last edited by wjh522996 on 2012-2-23 at 11:23 ] |

| For the problem of serious aggregation in nano-material synthesis, the new preparation method of monodisperse nano-metal oxide and its multiple compound was propsoed. The method was based on the study of sol-gel spontaneous combustion synthesis of nano-materials. Combined with the technology of explosives, shock wave produced in the thermal explosion may realize the effective separation of target product particles, eliminating the aggregation. The method was named as Gel Thermal Explosion Method. In the project, it was intended to adopt the method. The target products include NiZn ferrite and CuO. The project was to syudy the effect of the dosage of explosive(RDX as the representative), dosing process, etc. in the gel system on thermal explosion loose group, comparatively study spontaneous combustion method of gel and dispersion and performance of synthetic target products through thermal explosion method and explore the necessary conditions of thermal explosion formation of RDX in a gel system. Combined with numerical simulation, the multi-point and local-explosion deaggregation mechanism in gel system was proposed to provide theoretical support to monodisperse synthesis. The method provided an innovative idea for nano-materials deaggregation and also had the the same promotion significance for the preparation of other nanomaterials. |
