RESEARCH PROGRESS IN SILICIFICATION MODIFICATION OF WOOD. REVIEW
Wood is prone to decay, flammability and poor dimensional stability, which restrict its high-value application in furniture manufacturing, architectural decoration and other fields. As an advanced wood modification technology, wood silicification modification can significantly improve wood properties by impregnating silicon-based precursors into the interior of wood and forming SiO2 in situ. This paper reviews the latest research progress of wood silicification modification, elaborates on the structural characteristics of two types of silicon sources (organic and inorganic), sorts out the key points of current mainstream silicification processes, and analyses the improvement effects of wood silicification modification on wood properties such as dimensional stability, decay resistance and flame retardancy. It is proposed that future research is going to focus on the development of green and efficient new technologies and the exploration of organic-inorganic interface regulation mechanisms, aiming to develop multi-functional intelligent silicified wood.
