Abstract

The structure of materials determines their properties. Visualizing molecular or nanoscale structures is crucial to understanding this relationship. Carbon nanomaterials are a particularly good example. Single walled carbon nanotubes (SWCNTs) have different structures (chiralities), which translate into distinct optical colors and fluorescence properties. Nevertheless, it is difficult to comprehend why materials made only from carbon atoms have these different properties. Haptic materials can play a significant role in engaging newcomers, for public outreach as well as visualizing and explaining basic concepts of chemistry and physics for more advanced scientists. This article provides a beginner-friendly workflow to create 3D models of SWCNTs, graphene (nanoribbons/nanosheets) or modifications from scratch.
All used programs for chemical modeling are free to use, and no prior experience is required to follow the instructions. Exemplarily, a model of a single walled carbon nanotube (SWCNT) is created in Avogadro. This file is then imported into Blender to customize the layout. In a next step the generated files are processed (sliced) to translate it into the language of a 3D printer. This article provides a tutorial for 3D print SWCNTs and related materials, introduces the computational tools that are necessary, and discusses teaching examples.

Abstract Image

材料的结构决定其特性。分子或纳米级结构的可视化对于理解这种关系至关重要。碳纳米材料就是一个特别好的例子。单壁碳纳米管(SWCNTs)具有不同的结构(手性),从而转化为不同的光学颜色和荧光特性。然而,人们很难理解为什么仅由碳原子构成的材料具有这些不同的特性。触觉材料在吸引新手、公众宣传以及为更高级的科学家形象化地解释化学和物理基本概念方面可以发挥重要作用。本文提供了一个适合初学者的工作流程,从零开始创建超细线碳纳米管、石墨烯(纳米带/纳米片)或改性体的三维模型。所有用于化学建模的程序均可免费使用,无需任何经验即可按照说明操作。例如,在 Avogadro 中创建单壁碳纳米管(SWCNT)模型。然后将该文件导入 Blender,自定义布局。下一步是对生成的文件进行处理(切片),将其转化为三维打印机的语言。本文提供了三维打印 SWCNT 和相关材料的教程,介绍了必要的计算工具,并讨论了教学实例。
