A New Industrial Technology for Mass Production of Graphene/PEBA Membranes for CO/CH Selectivity with High Dispersion, Thermal and Mechanical Performance.

Polyether block amide (PEBA) nanocomposite membranes, including Graphene (GA)/PEBA membranes are considered to be a promising emerging technology for removing CO from natural gas and biogas. However, poor dispersion of GA in the produced membranes at industrial scale still forms the main barrier to commercialize. Within this frame, this research aims to develop a new industrial approach to produce GA/PEBA granules that could be used as a feedstock material for mass production of GA/PEBA membranes.

Thermal degradation and stability of cationic starches and their complexes with iodine.

Thermal degradation processes of cationic starch (CS) and CS-iodine complex were investigated by thermogravimetry (TG) in air and under nitrogen atmosphere at 10 °C min(-1) heating rate and compared. Moreover, the thermal stability of CS with different degree of substitution (DS) and their complexes with iodine was studied by TG under nitrogen atmosphere at different heating rates. The average E(a) values for CS were found to be slightly lower as compared to native starch, suggesting lower thermal stability of modified starches due to cationisation.
