Disaggregation of Nanodiamond Hard-aggregates By Mechano-chemical Superfine Crushing

利用超细粉碎机械化学法进行了纳米金刚石硬团聚体的解聚研究 ,测试了 2种优化助磨剂对解聚的活化指数 ,分析了 2种助磨剂加入粉碎前后及随后化学机械分散处理成悬浮液后纳米金刚石表面官能团的变化和表面电性、最终悬浮液的粒度、粉碎前后纳米金刚石的晶体结构。最终制得了粒度分布 10 0nm以内、平均

Disaggregation of nanodiamond hard aggregates by mechano chemical superfine crushing has been studied. Actiuation indexes of two types of optimum grinding aids in disaggregation of diamond aggregates are measured. The changes are analysed in surface function groups and surface charge of nano diamond obtained by adding the two types of grinding aids before and after grinding as well as by dispersing them into suspension using chemico mechanical method. Also, the final particle size of the suspension and the crystal structure of nano dianond before and before grinding are analysed. A stable nanodiamond suspension with a size of 1～100 nm, averaging 40 nm, can be prepared.
