For a certain pore structure, the pore size cannot be changed, only the solvent replacement can be used to reduce the surface tension of the liquid during drying to achieve the purpose of protecting the pore structure.
For a defined pore structure, the pore size cannot be changed, only through solvent replacement to reduce the surface pressure of the liquid when drying, so as to achieve the purpose of protecting the hole structure.
For a certain pore structure, it is impossible to change the pore size, only through solvent replacement to reduce the surface tension of the liquid during drying, so as to protect the pore structure.<br>
