A highly detailed review on ageing in polymers of intrinsic microporosity written in collaboration with Peter Budd (U. Manchester) and the late Darrell Patterson (U. Bath), which is to appear in Chemical Reviews is now on-line.
Our paper on Spirobifluorene based polymers of intrinsic microporosity (PIM-SBFs) is now out in the Journals of Materials Chemistry A. It includes some very nice ageing data that shows a good enhancement of selectivity over time – one example even reaching the 2015 upper bound for O2/N2.
A fascinating study on the gas permeability of a cross-linked Polymer of intrinsic Microporosity (PIM-Trip-TB) from Prof. Pei Li’s group at Beijing University of Chemical Technology.
So PIM-1 does have a glass transition temperature after all! Tg = 444 °C
It’s related to the flexibility of the spiro centre.
The addition of graphene oxide nano sheets to PIM-1 appears to greatly enhance performance for carbon capture:
Our paper on the use of easily prepared methanopentacene for making TB PIMs is now published in the Journal of Materials Chemistry A:
Reviews: I highly recommend reading this very nice and detailed overview of the use of new microporous materials, including polymers of intrinsic microporosity for important separations:
Also, here is a nice review on PIMs for gas separation membranes:
A fascinating and efficient new method for making Polymers of Intrinsic Microporosity with highly rigid structures is described in Macromolecules.
Preliminary data polymers appear to be useful for gas separations.
