A new polymer-inorganic nanocomposite SPEEK membrane filled with Cloisite 15A clay by introducing 2,4,6-triaminopyrimidine (TAP) as the compatibilizer for DMFC applications has been successfully prepared. The organoclay Cloisite is a material prepared from MMT and the cation ditallow. Tallow is a mixture of octa-decyl, hexadecyl, and tetradecyl, wherein octadecyl is the major component (>60%). Cloisite is a very promising additive in nanocomposite membranes, since it is already being organically modified from the natural MMT, which is expected to enhance the compatibility with organic polymers (Cervantes-Uc et al. 2007). 

Depending on the nature of the particles embedded in the polymeric matrix, polymer-inorganic hybrid membranes can be divided into two nonexclusive groups mixed matrix membranes (MMMs) and nanocomposite membranes (NCMs). 

Nanoparticles of other metal oxides, such as MgO, AI2O3, MgAl204, and VO2, were electrospun in different polymeric matrices. MgO NPs were used as inorganic fillers in polymers that are typically used to fabricate membranes (PVC, PVDF, PSU) in order to obtain nanocomposite membranes for protection against chemical warfare simulants [32].
