“…Gas separating carbon HFMs based on 3,3′4,4′‐benzophenone tetracarboxylic dianhydride and 80% methylphenylene‐diamine + 20% methylene diamine copolyimide precursor were studied for their permselective properties 272. The permeability (Barrer) of He, H 2 , CH 4 , O 2 , and N 2 were measured at atmospheric pressure and temperatures 313, 333, and 373 K and were found higher than those of the precursor.…”

The development in the area of surface modification of polymeric synthetic membranes since 2000 is reviewed. Many patents, articles, and reviews have been written on the development in the area of surface modification of polymeric synthetic membranes subjected to RO, UF, NF, gas separation (GS), and biomedical applications, mainly since 2000, but recently more attention has been given to the modification of their surfaces to obtain desirable results. In particular, most emphasis has been given to plasma treatment, grafting of polymers on the surface, and modifying the surfaces by adding SMMs (surface‐modifying molecules). New additives are synthesized to make the polymeric membrane surfaces either to be more hydrophilic or hydrophobic, aimed at improvement in selectivity and permeability of the membranes for GS, NF, and RO. Improvement in antifouling by surface modification is also a popular topic in the membrane industries. In the last 8 years, tremendous research efforts have been made on the development of antifouling membranes. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

“…Several process parameters, such as higher carbonisation rate and higher temperature, are considered as the key to achieve molecular sieve properties. Compared to polymer membranes (Kapantaidakis et al, 2003;Tin et al, 2004), carbon membranes exhibit better CO 2 /CH 4 and CO 2 /N 2 selectivity (Kim et al, 2005;Zhang et al, 2007;Favvas et al, 2008). 15…”

“…Polyimide BTDA-TDI / MDI (P-84) does not change its form and will not pass through a melting stage; thus, as a precursor to the advancement of carbon membranes, they are consistently preferred. This material also demonstrated superior gas selectivity for polymer membranes [13]. This polymer is a hopeful alternative for gas separation, and due to its compound and physical properties, it is ideal to be used as a main alternative for carbon membrane production.…”

Tubular carbon membrane was prepared from BTDA-TDI/MDI (P-84) polyimide as a main precursor that blends with nanocrystalline cellulose (NCC) through controlled pyrolysis condition. The effects of the final pyrolysis environment on 2 and 2 permeation levels were studied. By manipulating pyrolysis conditions during the process of pyrolysis with rate of heating at 3°C/min, a final temperature of 800°C and a stabilization temperature of 300°C, the performance of the carbon tubular membrane can be regulated based on a review of previous studies. The control of pyrolysis environment (helium, argon, and nitrogen gases) through the quality of carbon membranes influenced the permeation of gas properties themselves. By applying Ar gasses as a pyrolysis environment throughout the process of heat treatment, a better performance in gas separation was found. Single gas permeation tests of 2 and 2 were performed to examine the transport mechanism in the process of carbon membrane separation. The PI/NCC carbon membrane that undergoes Ar environment showed the most impressive finding with the highest selectivity of 8.23±3.27 for 2 / 2 213.56±2.17 GPU permeance of 2 .
