摘要
超快激光具有脉冲宽度短、峰值功率高的特点,相对于长脉冲对材料造成的热影响几乎为零,这使得利用超快激光加工材料逐渐受到科学界的重视。文中综述了超快激光辐照材料表面产生微纳结构的机理,总结了超快激光制备材料表面微纳结构的主要特点以及特殊性能的表现,针对超快激光加工不同种材料和采取不同种加工工艺两个方面进行论述,对材料表面结构的形貌形成、展现的性能及研究结论加以说明,并对各个工艺的优缺进行了讨论。最后对超快激光制备仿生功能表面和生物医学材料表面等最新发展趋势进行了总结,并对超快激光制备材料表面微纳结构在未来研究发展中会遇到的问题进行了展望。
Ultrafast laser has the characteristics of short pulse width and high peak power.Compared with the long pulse,the thermal effect on the material is almost zero,which makes the use of ultrafast laser processing materials gradually paid attention to by the scientific community.This article reviews the mechanism of micro-nano structures produced on the surface of ultra-fast laser irradiation materials,and summarizes the main characteristics and performance of micro-nano structures on the surface of ultra-fast laser prepared materials.The two aspects of the processing technology are discussed,the formation of the surface structure of the material,the performance and the research conclusion are explained,and the advantages and disadvantages of each process are discussed.Finally,the latest development trends of ultrafast laser preparation of biomimetic functional surface and biomedical material surface are summarized,and the problems encountered in the future research and development of ultrafast laser preparation material surface micro-nano structure are prospected.
