　　 Nano Green Printing and Manufacturing Technology

　　  

　　 【Abstract】

　　  

　　 Based on the fundamental scientific issues of nanomaterial preparation and functional inkjet patterning, a systematic Nano Green Printing technology has been developed by studying the construction of nanomaterials with differential wettability on material surfaces. The precise control of the conversion from translational kinetic energy to rotational kinetic energy before and after droplet collision has been achieved using patterned wettability surfaces. This process breaks through the scope of classical Newtons collision law and realizes a change in the motion mode of droplets before and after collision, providing new ideas for the preparation and precise control of high-precision patterns. Starting from the manipulation of droplets for three-dimensional shaping, spontaneous contraction of droplets in three-dimensional space has been achieved by using templates, enabling rapid assembly and shaping of three-dimensional micro/nano structures using single or multiple materials. Furthermore, the evolution of foam has been controlled using micro-templates, overcoming the long-standing challenge of patterned control of bubbles, and realizing the anti-Oswald ripening and patterning of bubbles. This has been used as a printing template for the assembly of multiple functional materials. In particular, by utilizing the advantages of droplet manipulation in nanoscale green printing, we discover the critical conditions for the scattering-diffraction transition of nano-photonic structures, an optical metamaterial detection chip has been developed for ultra-sensitive and rapid detection of novel coronavirus, influenza virus, and tumor markers. This opens up new ideas for the printing fabrication of functional devices and micro/nano chips, and establishes the theoretical and technical system of nanoscale green printing technology.

　　  

　　 基于納米材料制備及功能墨滴圖案化的基礎科學問題，通過研究納米材料構建浸潤性差異的材料表面，發展了系統的綠色印刷技術。利用圖案化浸潤性表面實現了對液滴撞擊液滴碰撞前后平動能向轉動能的轉化的精準調控。該過程突破了經典的牛頓碰撞定律描述范疇，首次實現了液滴碰撞前后運動方式的改變，為解決高精度圖案的印刷制備和精確調控提供了新的思路。從液滴操控三維成型出發，用模板誘導液滴在三維空間內自發收縮，實現了單一或多材料的三維微納結構的快速組裝成型。進一步，利用微模板操控泡沫的演化，克服了困擾百年的氣泡圖案化控制難題，實現了氣泡的反奧斯瓦爾德熟化和氣泡圖案化，并以此為印刷模板組裝多類功能材料。特別是利用液滴操控納米綠色印刷微納制造的優勢，發現了納米光子結構散射-衍射轉變的臨界條件，并發展了光學超材料檢測芯片用于新冠病毒、流感病毒和腫瘤標志物的超靈敏快速檢測，為功能器件與微納芯片的印刷制備開辟了新的思路，構建了納米綠色印刷技術的理論和技術體系。【BIOGRAPHY】
