There are many modification methods, including surface physical modification and surface chemical modification. The surface physical modification mainly through adsorption, encapsulation and other physical effects, using ultraviolet, plasma and other means to modify the surface of particles. The surface chemical modification is mainly carried out by coupling agent. Through the interaction of coupling agents containing organic groups and mesoporous silica materials, the functional groups are grafted on the mesoporous material pore wall by covalent bond to realize the functionalization of mesoporous silica materials.
