Chemists and physicians at University of Techno- logy Chemnitz, Germany, are funded more than EUR1 million by the German Research Foundation DFG for their research on hybrid materials. The scientists investigate on “Twin Polymerisation of organic-inorganic hybrid monomers on nanocom- posites.”
The aim is the manufacturing of hybrid materials. Such materials consist of an organic and inorganic part, therefore, connect carbonic and carbon free materials. “The resulting functional hybrid materials could be applied to catalysis or gas storage in the future,” according to Prof Dr Stefan Spange, chair Polymer Chemistry at Chemnitz University and speaker of the research group. On a broader scale, the aim of this research is to develop a new concept in material science.
Innsbruck scientists dry domestic leaves and pinewood like spruce in an industrial microwave site. That way, the wood dries from the core and the pores don‘t fully close. Afterwards, the up to one meter long wood samples are dipped into an impregnating solution consisting of sodium silicate and silica sol, and are dried in the microwave once again. Basically, the scientists copied a process hap- pening in nature: the petrification of wood.
Christian Lux at the Institute for Ion Physics and Applied Physics, Austria, explains: “The material is nontoxic and is considered to be ecologically sound. Silica nanoparticles form near the surface and are embedded in a wood matrix. Our results so far show that cheap domestic wood can be modi- fied through this nano infiltration method displaying similar properties as comparably expensive hard wood.”
