In particular, when using 1H-NMR to test the pore structure, the hydrogen-containing bond energy of the solvent used, molecular polymerization, hydrogen density, and chemical shift of functional groups must be considered.
In particular, when using 1H-NMR test hole structure, it is necessary to consider the hydrogen-containing bond energy of the solvent used, molecular polymerization, hydrogen density, chemical displacement of the function group, etc.
It is pointed out that the hydrogen bond energy, molecular polymerization, hydrogen density and chemical shift of functional groups of the solvents used must be considered when the pore structure is measured by 1H-NMR.
