The technical group of particle assembly started as a project-type technical group. In the group action, we catch up technical trends about wet and dry processes of high-speed coating, packing, building, deposition, stratification, and 3D assembly of nanoparticles, and distribute the trends and information for members, especially focusing on how to solve practical issues in industries and how to understand the fundamentals for developing and improving particle-assembling processes.
Current level of technology, trend and activities in future
In the wet process, high-speed film formation technology using the non-Newtonian nature of fluids and precision lamination technology on substrates with surface irregularities and permeability are attracting attention. Also, attempts at materials informatics, such as optimization of the coating process by machine learning, are beginning to be reported.
In the dry process, mainly the application of gas-phase dispersion/classification technology to nanoparticles as a pretreatment technology for lamination has been attracting attention. The key issue is to promote the functionalization of nanoparticle laminated films obtained by combining these dispersion/ classification techniques with the particle impact method. In particular, the application to bio-based materials is attracting attention, and the application development of nanoparticle deposition technology is expected in the dry coating of antibacterial agents and photocatalysts.
In addition, common issues for both processes are the control of the orientation of anisotropic particles, the development of visualization and measurement methods for the particle stacking process, and the elucidation of the stacking mechanism. In the future, it will be important to develop hybrids of dry and wet nanoparticle film formation technologies, precision multilayer film formation technology, 3D molding technology, particle stacking simulation technology and technology for utilizing materials informatics (MI).
