| 摘 要： | 由于纳米粒子的表面效应，用湿法制备出的纳米粉体的前驱——胶体的干燥已不能采用传统的干燥方法。根据胶体干燥的理论，阐述了纳米粉体干燥过程的团聚机理，并综述了纳米粉体在超临界干燥、共沸蒸馏、真空冷冻干燥、微波干燥等干燥领域的研究进展。

| Abstract: | Due to surface effect of nanometer particle,the colloid from wet process,namely the precursor of nanometer particles ,cannot be dried by conventional techniques.The mechanism of aggregation of nanometer particles during drying process according to the theory of drying colloid is described.And at the same time,the developments of such techniques as supercritical fluid drying,azeotropic distillation,vacuum freeze drying ,microwave drying,used for the drying of nanometer particles are reviewed. |

| Keywords: | nanometer powders supercritical fluid drying azeotropic distillation vacuum freeze drying microwave drying |
