Abstract
A method for manufacturing a modified porous composite structure includes steps as follows. A functionalized melamine sponge is provided, a porous organic framework source is provided, a connecting step is conducted, and a modifying step is conducted. The porous organic framework source includes a porous organic framework or a precursor of the porous organic framework. The porous organic framework and the precursor of the porous organic framework include a plurality of first ligands. Each first ligand includes at least one tetrazine group. In the connecting step, the functionalized melamine sponge is combined with the porous organic framework, so that a porous composite structure is obtained. In the modifying step, a reactive group of a modifying group donor is reacted with the tetrazine group, so that a modifying group of the modifying group donor is connected to the porous composite structure to obtain the modified porous composite structure.
