【摘要】 印刷技术为人类文明的传承做出了重要贡献,近年来也面临环境保护、电子出版等多方面的压力与挑战。基于纳米材料制备及功能墨滴图案化的基础科学问题,通过研究纳米材料构建浸润性差异的材料表面,实现绿色环保的高精度印刷制版,并发展系统的绿色印刷技术;[1]解决打印印刷技术基本单元"点、线、面、体"精细控制的关键科学技术问题;实现纳米材料的可控印刷与器件组装。[2]以不同纳米材料的制备与性质调控为基础,发展了应用于不同产业的绿色印刷制造技术:通过无机纳米颗粒和版材的结构与浸润性调控,摒弃感光成像原理,发展了非感光、无污染、低成本的纳米绿色制版技术,彻底根除了传统制版过程中的环境污染;[2]以金属纳米颗粒材料的研发为基础,利用绿色印刷技术替代传统电路加工业的刻蚀污染工艺,实现污染源头治理。通过聚合物纳米粒子的制备与图案化组装,发展了一系列性能优异的光子晶体器件。[3]目前,已初步形成较为完整的绿色印刷产业链技术,将努力推动印刷产业向"绿色化、功能化、立体化、器件化"发展。更多还原

【Abstract】 Print industry is one of the backbone industries in China, however, it produces huge amount of solid wastes, air emissions and wastewater. Based on the manufacturing of functional nanomaterials and controllable spreading and transferring of liquid droplets, they fabricated the superoleophilic patterns on the hierarchically structured superhydrophilic plate by ink-jet printing.[1] Thus the image area and non-image area can be generated on the plate, which can be directly used as the printing-plate. [2] It abandons the photosensitising process, and thus the new technology discharges no chemical pollutants, simplifies greatly the operation process, and lowered substantially the cost. Moreover, they employed the green printing technology in printed electronics based on metal nanoparticle ink, [3] which simplifies the complicated preparation process of traditional photolithography method, and significantly prevents discharge of chemical pollutant. Nanomaterial green printing technology will lead the printing industry into a new age of greenization and digitalization.更多还原
