Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description Novel inexpensive polymers from cheap hydrocarbon starting materials have ben developed with very high uptake of CO2 demonstrated. This results has been published in a leading materials chemistry journals. Highly CO2 permeable polymers of Intrinsic Microporosity have also been prepared that demonstrate good selectivity for CO2 over nitrogen and methane. High quality papers from this research are in preparation.
An ultrapermeable polymer of 2D chain structure has been developed with extraordinarily high CO2 permeability (>30000 Barrer) - one of the highest reported to date. This work was published in Nature Materials (2017, 16, 932) and was highlighted in Chemical and Engineering News (2017, 95(32), 6).
A 2019 paper in the high impact journal Energy and Environmental Science (2019, 12, 2733) proposed new upper bounds for the important gas pairs of CO2/CH4 (natural gas upgrading) and CO2/N2 (post-combustion carbon capture) to provide new benchmarks for these gas separations using polymer membranes.
Exploitation Route Hopefully, these materials will be of general interest for those working in gas separation membranes. Further disseminations activity is planned. A new EPSRC grant (R000468/1) has just started with the aim of exploiting highly permeable membranes in carbon capture.
