Development of composites from natural wastes based on plant tannins and lignocellulosic materials with nanomaterial additives.

The project is focused on the development of composite materials from natural renewable resources, which should take the form of relatively thin multi-functional design boards with a thickness of around 5 mm and which have real potential for practical application, especially in construction and interior design. The basis of these composites will be biopolymer substances that will be obtained from waste raw materials from agriculture, forestry, paper production, etc. The main attention will be paid to regionally available plant waste materials with a high content of lignocelluloses and polyphenols (tannins), which will be used as a basic component of polymer binders. Toxic aldehydes and crosslinkers will be completely or largely replaced by more environmentally friendly compounds and physical crosslinking procedures. Another part of these composites will be natural fibers and nanomaterials, which will give these composites other useful properties, such as resistance to insects, rot and mold, and unusual optical effects.
