摘要: Abstract In this work, gas permeability of composite membranes Polycarbonate (PC) and Multiwalled carbon nanotubes (MWCNTs) with different approaches have been examined. Effect MWCNTs alignment in PC matrix for as well selectivity was explored. It has observed that having aligned higher all gases compared to randomly oriented MWCNTs. For improving the further, functionalized Pd nanoparticles were dispersed found more selective towards hydrogen than other due absorption H 2 nanoparticles. These characterized by Raman spectroscopy, Scanning Electron Microscope (SEM) Fourier transform infrared spectroscopy (FTIR) confirmation functionalization distribution matrix.
