摘　　要：从3个方面较系统地对溶液接触条件下纳米包装材料中纳米颗粒的迁移研究现状进行综述。介绍了推导纳米颗粒迁移的Piringer理论模型和Simon理论模型;归纳了纳米颗粒在液态高分子材料和固态高分子材料中的迁移途径;分析了纳米金属、碳纳米管、纳米黏土3种纳米颗粒迁移量实验数据。在此基础上,对该领域未来的研究方向进行了展望,将朝以量子点为模型颗粒研究纳米颗粒的迁移和材料降解对纳米颗粒迁移的影响方面发展。The release of nanoparticles from nanocomposite packaging materials in solvent contact condition was systematically reviewed in three aspects:Piringer theoretical model and Simon theoretical model were introduced to deduce the migration of nanoparticles;migration pathways of nanoparticles in liquid macromolecular materials and solid polymer materials were concluded;experimental data of the migration volume of nanoparticles of nano-metal,carbon nano-tube and nanoclay were analyzed.On this basis,the prospects of future research were suggested as in the direction of study on the migration of nanoparticles by quantum dots as model particles and the effects of material degradation on migration of nanoparticles.
