The need for membranes with optimized properties was activated many researches in this field and development of hybrid or nanocomposite membranes is one of the recent contributions.
In this research, using special rubbery and glassy polymers and with the aim of nanotechnology for improvement of polymer properties, nanocomposite membranes are synthesized which have the ability of high permeability and reverse selectivity. The later ability means that large molecules such as butane permeate faster than small molecules such as methane or nitrogen through membranes. This ability eliminates the recompression process after separation in applications such as natural gas purification. The results showed over 100% increase in permeation coefficients of nanocomposite membranes compare to ordinary membranes.
