A research team from the KAUST (King Abdulla University of Science and Technology) comes up with three-dimensional materials after the honeycombs. Suzana Nunes heads the group. The research has paved the way for the scientists to come up with the development of the selective filters. The method of the filter development is fast and straightforward. These selective filters find their use in the viral or the pollutants removal process.

It was for decades that the researchers focused on the honeycombs to explore its structural complexity. It has been the basis for innovations of many materials, which trace their way to the aerospace industry. Such materials hold importance for their strength to weight ratio.

The current scientific study focuses on the development of the stable porous materials. The materials have an extended surface area and the selective activity of material extraction.

To replicate the honeycomb intricacy at the level of the nanoscale represents a significant challenge. However, the KAUST research team under the guidance of the Suzana Nunes proposed a simple method to produce a flexible but complexly structured film. The film consists of the interconnected networks of the regularly shaped pores. The entire production process is mastered to be accomplished within five minutes.

The researchers of the KAUST collaborate with the scientist of the Imaging and the Characterization Core Lab. The collaboration was meant for the demonstration of the method with the help of the polystyrene-b-poly (t-butyl acrylate) (PS-b-PtBA). The polystyrene-b-poly (t-butyl acrylate) (PS-b-PtBA) is a block complex polymer.

The reports analyzed various concentrations of the PS-b-PtBA in conjunction with different solvent mixtures. Later the entire solutions were cast on glass plates. To promote nucleation and cavity growth, they subjected the samples for the evaporation process at different time intervals. Later, the solvent washed off the remaining film. The solvent washing stopped the operation of the phase separation.

The flexible film finds its use in the process of the virus filtration, and as the biological scaffolds. The biological scaffolds are meant for the bone regeneration process.

The study finds its way to the journal Science Advances.
