Nanomaterials refer to materials whose dimensions reach the nanoscale (1–100 nm) in one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D) directions. Based on their dimensionality, they are categorized into 1D, 2D, and 3D nanomaterials. Among these, 2D materials represent a significant class of substances characterized by a thickness reduced to the atomic layer limit in one dimension, while maintaining relatively larger dimensions in the other two directions (Zhu and Wang in J Chin Ceram Soc 45:1043–1053, 2017 [1]).

摘要

Nanomaterials refer to materials whose dimensions reach the nanoscale (1–100 nm) in one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D) directions. Based on their dimensionality, they are categorized into 1D, 2D, and 3D nanomaterials. Among these, 2D materials represent a significant class of substances characterized by a thickness reduced to the atomic layer limit in one dimension, while maintaining relatively larger dimensions in the other two directions (Zhu and Wang in J Chin Ceram Soc 45:1043–1053, 2017 [1]).
