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.

 

基于纳米材料制备及功能墨滴图案化的基础明升体育app问题，通过研究纳米材料构建浸润性差异的材料表面，发展了系统的绿色印刷技术。利用图案化浸润性表面实现了对液滴撞击液滴碰撞前后平动能向转动能的转化的精准调控。该过程突破了经典的牛顿碰撞定律描述范畴，首次实现了液滴碰撞前后运动方式的改变，为解决高精度图案的印刷制备和精确调控提供了新的思路。从液滴操控三维成型出发，用模板诱导液滴在三维空间内自发收缩，实现了单一或多材料的三维微纳结构的快速组装成型。进一步，利用微模板操控泡沫的演化，克服了困扰百年的气泡图案化控制难题，实现了气泡的反奥斯瓦尔德熟化和气泡图案化，并以此为印刷模板组装多类功能材料。特别是利用液滴操控纳米绿色印刷微纳制造的优势，发现了纳米光子结构散射-衍射转变的临界条件，并发展了光学超材料检测芯片用于新冠病毒、流感病毒和肿瘤标志物的超灵敏快速检测，为功能器件与微纳芯片的印刷制备开辟了新的思路，构建了纳米绿色印刷技术的理论和技术体系。【BIOGRAPHY】
