摘　　要：Essential oils are a volatile and aromatic substance with a variety of active biological activities.However,the excessive volatility and inconvenience of the use of essential oils limit their applications.In this study,we developed a reactive mesoporous silica nanoparticle(rMSNs)based on cyanuric chloride modification for essential oil encapsulation and commodity adhesion.The large pore volume and specific surface area of rMSNs facilitate the nanoparticles adhering to a large amount of essential oil and achieve the sustained release of essential oil,thus prolonging the fragrance retention time of essential oils.The reactive nanoessential oils can form covalent bonds with the wallpaper,thereby remarkably improving the adhesion of the reactive nano-essential oils on the wallpaper and preventing the reactive nano-essential oil from deadhering from the wallpaper.The active nano essential oil simultaneously overcomes the intense volatility of the essential oil and inconvenience in use,has a simple preparation process and low cost,and has great application potential.
