5. 내 용 : There are innumerable examples for mass products which benefit from incorporating tailor-made nanoparticles, e.g. printing inks, automotive coatings, UV sun-block creams and plastics. The advantage of aerosol processes in comparison to standard liquid based processes is the exact control of particle properties (size, layer thickness, morphology, crystallinity), a higher degree of purity e.g. needed in electronic industry and in many cases lower production costs e.g. due to the avoidance of solvents. Insight into the fundamental behavior of the aerosols and the interactions within the entire process chain is a prerequisite in order to design optimum processes with respect to product properties, energy consumption, raw material input and environmental impact. The complexity of the process chain is increased due to the fact that the relevant mechanisms tend to occur simultaneously with very complex interaction kinetics that differ substantially from those found, say, in environmental problems. An integrated view of all process parameters, intermediate and final product properties is necessary during the entire process. In this presentation the complex process chain including formation, formulation and post-processing is demonstrated by means of two different chemical products.
