Super Black Solid Wood

Record breaking super black wood
Current #superblack materials are structures built up from tiny elementary building blocks - a process called bottom-up synthesis. Such processes are usually time-demanding, energy intensive and rely on synthetic precursors. Nevertheless, although there have been some improvements, most super black materials are still sensitive to touch, thus limiting their real-life applications. Recognizing these limitations, scientists at Aalto University and VTT Technical Research Centre of Finland set out to create a wood-based material with ultra-low light reflectance, a fully bio-based "super black" material. The team has harnessed the natural properties of wood to develop a bio-based alternative to existing super black materials. This innovative approach promises to be a strong, nontoxic material that is capable of absorbing an astounding 99.65% of light, in effect breaking the record for the blackest solid wood material ever reported.
