Abstract

This study presents an approach for fabricating durable superhydrophobic surfaces on 3D-printed structures inspired by the architectural design of beehives. Using fused deposition modeling (FDM) 3D printing technology, hexagonal macrostructures were fabricated using polylactic acid (PLA) filament. These structures were designed to protect an inner layer of hydrophobic nanoparticles, which were deposited by a squeegee coating method and immobilized by a photocurable resin. The relationship between hexagonal area size (ranging from 24 to 200 mm²) and the durability of superhydrophobic properties under frictional stress was systematically investigated. Wettability and surface morphology analyses performed before and after the friction tests showed that structures with hexagonal areas between 40 and 80 mm² retained superhydrophobicity even after 100 friction cycles, while larger hexagonal configurations exhibited diminished performance. To elucidate the underlying mechanisms, a theoretical model based on the Cassie-Baxter equation was developed and compared with experimental values alongside surface observations. This research advances the development of durable and functional superhydrophobic surfaces in 3D-printed materials, with promising implications for industries requiring water-repellent and self-cleaning technologies.

受蜂巢建筑启发的3d打印结构上耐用的超疏水表面。

这项研究提出了一种在3d打印结构上制造耐用超疏水表面的方法，该结构的灵感来自于蜂巢的建筑设计。采用熔融沉积建模（FDM） 3D打印技术，用聚乳酸（PLA）长丝制备了六边形宏观结构。这些结构被设计用来保护疏水纳米颗粒的内层，这些纳米颗粒是通过橡胶刮涂法沉积的，并由光固化树脂固定。系统地研究了摩擦应力作用下六边形面积大小（24 ~ 200 mm2）与超疏水性能耐久性之间的关系。在摩擦测试前后进行的润湿性和表面形貌分析表明，即使在100次摩擦循环后，六边形面积在40至80 mm2之间的结构仍保持超疏水性，而较大的六边形结构的性能则有所下降。为了阐明潜在的机制，建立了一个基于Cassie-Baxter方程的理论模型，并与实验值和地面观测值进行了比较。这项研究推动了3d打印材料中耐用和功能性超疏水表面的发展，对需要防水和自清洁技术的行业具有重要意义。
