Formula IX – Multiscale Structures and Functionalities for Future Formulation


In the market there is a clear trend towards more complex materials which exhibit superior and often multiple functionalities. Examples therefore are battery materials, printing inks, catalysts, cosmetics or pharmaceutical formulations. These kind of materials have to be formulated on different levels ranging from molecule scale to the micro size regime. In order to achieve the targeted properties new methods are required because standard processes are not capable to deal with the often very fast reaction and interface kinetics. Thus, the key process and formulation parameters cannot be controlled within the required time frame to uniformly deliver the targeted properties. In addition, the key mechanisms (e.g. molecular transport, adsorption and desorption, crystal growth, morphology change, agglomeration) tend to occur simultaneously with complex interaction kinetics. Thus, multiple process steps have to be integrated into one new-designed process concept.


Pre-designed particles are often used as building blocks in complex formulations to obtain application properties like scratch, rub and dirt resistance, water repellency, moisture and grease barrier, gloss, surface smoothness or a tailored release of actives. Therefore, a precise adjustment of size, structure and interface properties of the particles is often required as well as their transfer into formulations to enable the desired application properties.


The entire process chain has to be considered on multiple scales (micro-, meso- and macroscale) including synthesis, stabilization, formulation and post-processing. The microscale is important to deal with the very fast building and reaction kinetics. The mesoscale, where often a transition from two or more competing mechanisms takes place, is fairly understood, but especially in this regime material properties are often crucially influenced. The macroscale is required to describe and scale-up the desired apparatus and processes.


The conference scope is on formulations within these multiple scales. Fundamental studies on chemical and physical aspects of materials, interfaces and complex material compositions as well as synthesis, formulation and application technologies are highly welcome. In addition, characterization, modelling and simulation is of increasing interest esp. for complex material systems. Transfer from fundamental research to industrial application is another focus to highlight the importance of formulation technology for future industrial products.

A new focus should be on coating technologies where formulations are crucial to obtain desired film properties. In a separate session developments and discoveries in the application and solidification of thin liquid films should be presented. Topics of interest range from fundamentals on traditional coating and drying processes of traditional high-capacity coating industries, the impact of formulation on coating performance, to emerging applications such as battery and fuel cells, and electronic displays.
