Description
Technical Field

Background
The development of the preparation method of the large-area nano-particle single-layer film based on the SA film forming technology has important significance in the fields of optics, electrics, chemical industry, biology and the like. The nano-particle has monodispersity, can be used for constructing photonic band gap materials by utilizing the spherical morphology and the uniformity of the particle size, and is suitable for the fields of chemical sensing, flexible display, biological coding and the like; secondly, the large-area ordered nano particles can be used as a template agent for constructing a porous body phase material with a regular structure and a large specific surface area, and are suitable for developing sensing and catalytic materials with high sensitivity and high catalytic performance; in addition, the nano-particle template after various modifications can be used for the fixation of specific substances such as biomacromolecules such as nucleic acid, protein and the like and the multifunctional biochemical analysis and detection with high flux and high specificity. Recently, scientists have developed a method of nanosphere etching technology (NSL) for preparing nanostructures, and the key to preparing 2D nanoarrays using the NSL technology is that a periodic barrier layer must be formed by a self-assembly method to realize periodic micro-nano pattern transfer. The method uses nano colloidal spheres with narrow size distribution, such as polystyrene nano particles, and utilizes the self-assembly effect of the nano colloidal spheres with regular arrangement height to prepare the film, the required instruments and equipment are low in cost, the process is easy to operate, and large-area periodic array structures with different nano sizes can be obtained on various substrates only by changing the particle sizes of different nano particle spheres.
In summary, the self-assembly technology is currently recognized as a key technology for preparing cheap and efficient nano materials, and is widely applied and researched in laboratories around the world. However, the reported single-layer film prepared by the self-assembly technology often has the problems of poor forming quality, long forming time, small forming area and the like, and can only be used for experimental research and cannot meet the requirement of large-scale production. In summary, a satisfactory self-assembly film-making technology with high forming quality, long forming time, large forming area and large-scale production is not available, so that a device which facilitates nano material assembly and improves efficiency and is suitable for large-area dense nanosphere film assembly is urgently needed in the field.
