Problems solved by technology

[0003] A key problem in the design and preparation of nano-network polymer materials is the construction of network units. The nano-network polymers with precisely customized network units that have been prepared so far require a cumbersome preparation process of network unit precursors. Most of the porous polymers prepared by this method lack stable microporous framework structure, which also affects the hierarchical and structural rigidity of porous polymers.
Therefore, it is still a great challenge to prepare nano-network polymers with stable microporous framework structure and precisely tailored network units.
