Development of novel co2 selective chitosan membrane blended with synthetic amines and natural amines of silk fibroin and sericin

Abstract

The major objective of the present work is to develop a thermally stable biopolymer based membrane for CO2 separation using facilitated transport mechanism The biopolymer chitosan CS enables facilitated transport of CO2 by dint of the amine group present in its structure is thermally stable in absence of crosslinking and possess good film forming ability The CO2 permeance of the CS membrane with poly ether sulfone PES as a support was 12 5 GPU and CO2 N2 selectivity was 54 at 90 194 176 C wit...
