Increasing the Permeability of Carbon Dioxide and Nitrogen Gases Through a Polymer Membrane Consisting of a Modified Polyether Block Amide and Experimental Design

Newly, Pebax polymer (pure and composite polyether block amide) has been extensively applied for CO2 elimination from air contaminants. The Pebax involves of polyamide (PA) and stretchy polyether (PEO) portions, which can suggest excellent solubility as well as bulk-free fractional volume for CO2 permeation. In the present work, the polymeric nanocomposite membranes (Pebax/PEG/NCS) were synthesized by adding different amount of nanochitosan particles (NCS) and polyethylene glycol (PEG) to the Pebax with applying Taguchi’s experimental design with Minitab software as well as using thermal phase separation method. The input variables to the software included 4 factors at 4 levels, namely wt
