12. Inkjet Printing of Self‐Supporting and Self‐Contained Structured Objects Onto Liquid Surfaces

Author

Goedel, W.A., Gläser, K., Mitra, D., Thalheim, R., Ueberfuhr, P., Hammerschmidt, J., Baumann, R.R., and Publica

Abstract

Some applications in miniaturized fabrication like valves or force sensors require self‐supporting structures. These may be generated on top of a solid substrate and separated from it afterwards, but this separation is an additional manufacturing step and may stress the structure. Therefore, it may be of advantage to create the desired objects directly on top of a liquid. Here, it is shown that self‐supporting and self‐contained structures including lines of defined width, full tone squares and delicate structures with non‐uniform line width, edges and openings can be prepared by inkjet printing of a photo‐curable ink onto a water surface followed by irradiation with ultraviolet light and lift‐off. To make this feasible, convection, spreading, and dewetting of the ink from the water surface has to be suppressed by controlling the timing of the irradiation, the mobility of the water surface and the long and short range interactions between the printed ink and the water substrate. These tasks may be achieved via addition of soluble amphiphiles or via spreading of water insoluble amphiphiles or hydrophobized particles onto the water surface prior to printing. Best results are obtained by printing the desired structures onto a water surface that bears a monolayer of hydrophobized particles.

22. Printing Reinforcing Structures onto Microsieves That Are Floating on a Water Surface

Author

Goedel, Werner A., Gläser, Kerstin, Mitra, Dana, Hammerschmidt, Jens, Thalheim, Robert, Ueberfuhr, Peter, and Baumann, Reinhard R.

Abstract

This article describes the preparation of hierarchically structured microsieves via a suitable combination of float-casting and inkjet-printing: A mixture of hydrophobized silica particles of 600 nm ± 20 nm diameter, a suitable non-water-soluble nonvolatile acrylic monomer, a nonvolatile photoinitiator, and volatile organic solvents is applied to a water surface. This mixture spontaneously spreads on the water surface; the volatile solvents evaporate and leave behind a layer of the monomer/initiator mixture comprising a monolayer of particles, each particle protruding out of the monomer layer at the top and bottom surface. Photopolymerization of the monomer converts this mixed layer into a solid composite membrane floating on the water surface. Onto this membrane, while still floating on the water surface, a hierarchical reinforcing structure based on a photocurable ink is inkjet-printed and solidified. In contrast to the nonreinforced membrane, the reinforced membrane can easily be lifted off the water surface without suffering damage. Subsequently, the silica particles are removed, and thus, the reinforced composite membrane is converted into a reinforced microsieve of 350 nm ± 50 nm thickness bearing uniform through pores of 465 nm ± 50 nm diameter. This reinforced microsieve is mounted into a filtration unit and used to filter model dispersions: its permeance for water at low Reynolds numbers is in accordance with established theories on the permeance of microsieves and significantly above the permeance of conventional filtration media; it retains particles exceeding the pore size, while letting particles smaller than the pore size pass.
