摘要
微纳米材料的性能受到其形貌的影响,以维度为分类原则,综述了不同类型银微纳米的制备和应用进展。零维的银纳米材料包括银原子和粒径小于15 nm的银纳米粉,主要提高催化性能、抗菌及光性能;一维的银纳米线由化学还原法制备,主要用于透明纳米银线薄膜制备的柔性电子器件;二维的银微纳米片可用球磨法、光诱导法、模板法等方法制备,其在导电浆料及电子元器件等方面有广泛的应用;三维的银微纳米材料包括球形和异形银粉,球形银粉主要用于导电浆料填充物,异形银粉主要应用催化、光学等方面。改善制备方法,实现微纳米材料的形貌控制,提升产物稳定性,是银纳米材料研究的发展方向。
The performance of micro-nano materials is affected by their morphology.Using dimensions as the classification principle,the preparation and application progress of different types of silver micro/nano are reviewed.Zero-dimensional silver nanomaterials include silver atoms and silver nano-powder with a particle size of less than 15 nm,which mainly improve catalytic performance,antibacterial and optical properties.One-dimensional silver nanowires are prepared by chemical reduction methods and are mainly used for flexible electronic devices made of transparent nanosilver wire films.Two-dimensional silver micro-nano flakes can be prepared by ball milling,photo-induction,and template methods,and they have a wide range of applications in conductive pastes and electronic components.Three-dimensional silver micro-nano materials include spherical and irregular silver powder.The spherical silver powder is mainly used for conductive paste filling,while the irregular silver powder is mainly used in catalysis and photo-latent applications.Improving the preparation method,realizing the morphology control of micro-nano materials,and enhancing the stability of products are the development directions of silver nano-materials research.
