Abstract: Mixed Matrix Membrane (MMM) are composite membranes for gas separation and comprising a quantity of inorganic filler particles, in particular metal organic framework (MOF), dispersed throughout a polymer matrix comprising one or more polymers. This disclosure is directed to MOF functionalized through addition of a pendant functional group to the MOF, in order to improve interaction with a surrounding polymer matrix in a MMM. The improved interaction aids in avoiding defects in the MMM due to incompatible interfaces between the polymer matrix and the MOF particle, in turn increasing the mechanical and gas separation properties of the MMM. The disclosure is also directed to a MMM incorporating the surface functionalized MOF.

Abstract: A method of synthesizing an ionic liquid, includes reacting a 1,2,3-triazole including at least one of a 4-substituent or a 5-substituent with a hydroxide compound having the formula R+OH? in a dehydration reaction, wherein R+ is an ionic liquid cation. R+ is a five-membered heterocyclic cation, an aromatic cation, a sulfonium cation, an ammonium cation, or a phosphonium cation. In a number of embodiments, R+ is a pyridinium cation, a bipyridinium cation, an amino pyridinium cation, a pyridazinium cation, an ozaxolium cation, a pyrazolium cation, an imidazolium cation, a pyramidinium cation, a triazolium cation, a thiazolium cation, an acridinium cation, a quinolinium cation, an isoquinolinium cation, an orange-acridinium cation, a benzotriazolium cation, a methimzolium cation, a sulfonium cation, an ammonium cation, or a phosphonium cation.
