N2 - Assessment and manufacturing of tubular carbon membrane from P84 co-polyimide (PI) mixtures and nanocrystalline cellulose (NCC) are described in this study. According to the previous work, a hypothesis was formulated stating that manipulation of carbonization parameters can control the performance of a tubular carbon membrane. This study introduces effective dip-coating methods for high-performance tubular carbon membrane production. On the basis of the outcome of this study, the coating-carbonization cycle (one, two, three, or four times) has been recognized as a major influence on the separation efficiency. Gas separation performance, selectivity, permeability, and the transport mechanism of the carbon membranes were adequately evaluated by pure O2 and N2. The PI/NCC scanning electron microscopy images show that all of the carbon membrane samples are composed of a dense structure, whereas the Fourier transform infrared spectroscopy analysis exposes that the existence of functional groups is decreased for all coating-carbonization cycle samples. The X-ray diffraction result shows that the membrane carbon structures are amorphous in nature. In this research, the application of two coating-carbonization cycles has resulted in a carbon membrane with the highest selectivity and O2 permeability, which are 9.29 ± 2.54 and 29.92 ± 2.98 GPU, respectively.
