摘要

阳极氧化可通过电化学参数控制制造纳米结构。虽然有多种方法可以制造局部或图案化的氧化层，但许多方法都很复杂且耗时。本研究采用商用 3D 打印机进行高速（1 毫米/秒）阳极氧化，在钛基底上以 G 代码设计的图案形成 TiO2 纳米管层。利用 XRD、SEM、XPS 和模拟电场分布分析进行的综合表征揭示了定义明确的纳米结构，并提供了对形成机制的见解。此外，与原始二氧化钛相比，紫胶锚定二氧化钛的电致变色性能有了显著提高，反射率差异更大（46.2% 对 6.85%）。这种三维打印-阳极氧化混合方法提供了一种快速制造图案化二氧化钛纳米结构的方法，为具有更强光学调制能力的电致变色设备带来了希望。

Fabrication of patterned TiO2 nanotube layers utilizing a 3D printer platform and their electrochromic properties

Anodization enables nano-structure fabrication through electrochemical parameter control. While various approaches exist for creating localized or patterned oxide layers, many are complex and time-consuming. This study adopted a commercial 3D printer for high-speed (1 mm/s) anodization, forming TiO₂ nanotube layers on Ti substrates in G-code-designed patterns. Comprehensive characterization using XRD, SEM, XPS, and simulated electric field distribution analysis revealed well-defined nanostructures and provided insights into the formation mechanism. Furthermore, viologen-anchored TiO₂ showed significantly improved electrochromic performance compared to pristine TiO₂, with a higher reflectance difference (46.2% vs. 6.85%). This 3D printing-anodization hybrid method offers a rapid approach to fabricating patterned TiO₂ nanostructures, showing promise for electrochromic devices with enhanced optical modulation capabilities.

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
