Chemical Modification of Wood Waste for the Production of Composite Materials as a Prospective Solution to the Recycling Issue

The issue of increasing the physical and mechanical properties of composites by modifying the wood is considered. To improve the quality and increase the resistance of wood filler to various influences, the acetylation has been proposed, which is carried out aiming to introduce the acetyl groups into the composition of wood by replacing free hydroxyl radicals. The effectiveness of acetylation as a method of modifying wood filler in the production of composite materials in order to improve their physical and mechanical properties (dimensional stability, hydrophobicity and biostability) has been experimentally confirmed.
