摘要：Plant-derived extracts have been used in various aspects of domestic life in recent years due to their significant antibacterial activity. Mesoporous silica nanomaterial (MSN) is a perfect adsorption carrier for the application of decorated blockboards due to the properties of temperature and pressure resistance. This work proposed a green and eco-friendly strategy of antibacterial decorated blockboards by loading MSN with plant-derived extracts as agents. We have successfully prepared uniform spherical mesoporous silica with an average particle size of 80.32 nm and adjustable specific surface area (530-866 cm2/g). The effective encapsulation of MSN allowed plantderived extracts to exhibit significant antibacterial effects against Escherichia coli and Staphylococcus aureus on the decorated blockboards. The MSN had the best loading content for the matrine, which can reach 22.7 %. Moreover, the loading discrepancy and adsorption paths of MSN on well-versed plant-derived extracts, e.g. catechin, matrine, and citral, was profoundly explored. A dual path adsorption theory involving physical adsorption through Van Der Waals force and chemical adsorption through hydrogen bonding networks or chemical bonding has been proposed by multi-representational methods. The results showed that the chemical adsorption of catechin was slightly stronger than the physical adsorption, accounting for 55.6 % of the total loading content. The physical adsorption of matrine and citral was more dominant, accounting for 60 % and 68.7 % of the total loading content, respectively.
