Abstract
A method of synthesizing a mixed matrix membrane (MMM) film. The method includes: synthesizing a polymer including a polynorbornene or a polytricyclononene; synthesizing covalent-triazine frameworks (CTFs); preparing a polymer solution by dissolving the polymer in a first solvent; preparing a filler solution by dispersing the CTFs in a second solvent; adding the polymer solution to the filler solution while stirring the filler solution, forming a casting solution; pouring the casting solution into a membrane support; and drying the poured casting solution in the membrane support to form the MMM film including the CTFs.

A method of synthesizing a mixed matrix membrane (MMM) film, the method comprising:
- synthesizing covalent-triazine frameworks (CTFs), the synthesizing comprising performing a trimerization of a nitrile monomer, the nitrile monomer comprising two or more nitrile groups;
- preparing a filler solution by dispersing the CTFs in a solvent;
- adding a polymer solution comprising a polynorbornene or a polytricyclononene to the filler solution while stirring the filler solution, forming a casting solution;
- pouring the casting solution into a membrane support;
- and
- drying the poured casting solution in the membrane support to form the MMM film comprising the CTFs.
A mixed matrix membrane (MMM) comprising:
- a polymer matrix (PM) comprising a polynorbornene or a polytricyclononene;
- and
- a filler dispersed in the PM, the filler comprising covalent-triazine frameworks (CTFs).
