Creation of functional particles and porous structures by spray printing (SFB 1411)

The objective is the design of optimised porous stationary phase columns for nanoparticle chromatography, using the controlled assembly of individual building blocks by spray printing. Having established a scalable technique for layer-by-layer deposition of individual droplets containing the stationary phase material, we target the transition to full column-scale packings with predetermined, complex structure. The project will progress to structure formation across multiple layers, addressing defects and non-uniformity prevalent in conventional packing methods and include surface functionalities. Based on experimentally determined diffusion coefficients, optimised porous networks will be predicted by simulations under uncertain conditions and experimentally realised.
