摘要

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。

Non-sticky superhydrophobicity on polypropylene surfaces achieved via single-step femtosecond laser-induced processing in n-hexadecane liquid

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.
