Abstract

The preparation of superhydrophobic polypropylene (PP) surfaces for biosafety is a pressing challenge in the food and medical industries. We achieve superhydrophobicity on commercial PP using a single-step process based on femtosecond (fs) laser-induced micro/nano texturing in n-hexadecane. Analysis of the wetting behavior after fs laser texturing revealed that 120 times of repetitive texturing, with a contact angle (CA) exceeding 150° and a rolling angle below 1° yielded optimal results. The generation, growth, and evolution of micro/nanostructures over processing times were investigated to establish a direct correlation between the micro/nanostructures and hydrophobicity. Furthermore, we elucidated the interactions between fs laser pulses and different material types in air, water, and n-hexadecane to explain the formation of micro/nanostructures formed in n-hexadecane.

在正十六烷液体中通过单步飞秒激光诱导加工实现聚丙烯表面的不粘超疏水性

制备用于生物安全的超疏水聚丙烯（PP）表面是食品和医疗行业面临的一项紧迫挑战。我们在正十六烷中采用飞秒（fs）激光诱导微/纳米制绒的单步工艺实现了商用聚丙烯的超疏水性。对飞秒激光纹理加工后的润湿行为分析表明，重复纹理加工 120 次，接触角（CA）超过 150°，滚动角低于 1°，即可获得最佳效果。我们还研究了微/纳米结构在加工过程中的生成、生长和演变，从而确定了微/纳米结构与疏水性之间的直接关系。此外，我们还阐明了 fs 激光脉冲与空气、水和正十六烷中不同材料类型之间的相互作用，以解释在正十六烷中形成的微/纳米结构。
