[0043] 1. Preparation of structured packing
[0044] In the embodiment of the present invention, nano-silica is used as a structural filler, wherein the nano-silica is prepared by a sol-gel method, and the particle size is controllable in the range of 0.02um to 10.0um. Its microstructure is as follows:figure 1 As shown, it is a perfect spherical structure. The nano silicon dioxide has the advantages of consistent light refraction, good surface polishing performance, strong combination with monomers, and can greatly improve the physical and mechanical properties of the material.
