Application fields and development prospects of microporous
molecular sieves(2)
Thirdly, due to the diversity and controllability of the above structures and properties, a large number of advanced functional materials based on microporous substances have been developed and developed on this basis. open up.
The microporous host-guest composites can be classified into the following four categories according to the different assembling guest species. The first type is a composite system composed of a porous body and a metal or metal group; the second type is a composite material formed by a porous body, a polymer and a carbon material, and the carbon material includes carbon nanotubes and fullerenes; the third type is mainly It is a host-guest composite material composed of functional nano-water particles such as inorganic semiconductors formed in the pores or cavity cages of the porous host; the fourth category is the porous host and organic molecules, metal complexes, family compounds, supramolecules, drug molecules, etc. The formed host-guest material. Considering the pore size of the host material, the size and properties of the guest molecule, people have developed different assembly, grafting, anchoring, loading and other means to prepare and synthesize a large number of composite host-guest materials with specific properties, and their specific aggregation states such as various Various functions and types of membranes, nano-states, special morphologies and perfect crystals. These materials have developed and developed a large number of specific functions by virtue of the functions of highly dispersed guest species, or the synergistic effect of host and guest species, and formed a new scientific field with important development prospects.
