解读GB/T32269-2015《纳米科技纳米物体的术语和定义纳米颗粒、纳米纤维和纳米片》

摘要

国家标准GB/T 32269—2015《纳米科技纳米物体的术语和定义纳米颗粒、纳米纤维和纳米片》将于2017年1月1日实施。术语和定义是标准化工作的重要内容，纳米物体的术语和定义标准是纳米科技领域标准体系的基础。为了让更多从事纳米产业相关人员充分理解使用基础标准，本文对GB/T 32269—2015中涉及的纳米领域相关术语及词义进行了具体图文示例解读，包括“纳米尺度”“量子点”的具体释义；纳米颗粒形成“团聚体”的原因；不同维度纳米物体的具体分类及举例；“纳米管”“纳米棒”“纳米线”的区别；“团聚体”和“聚集体”的不同等内容。%National standard of “Terminology and definitions for nano-objects——Nanoparticles, nanofibre and nanoplate”(GB/T 32269—2015) will be implemented from January 1, 2017. The standard was the basis on the nanotechnology standard system in nano-ifeld. For the sake of understanding and using the foundational standard preferably, the typical examples and demonstration for terminology and deifnitions of nano-objects were interpreted in this paper, such as the detail discription of“nanoscale”and“quantum dot”,the reason for agglomerate of nanoparticles, nano-object on different dimension, the difference among “nanotube” , “nanorod” and “nanowire”, as well as the difference between“agglomerate”and “aggregate”.
