1Moisture-Resistant Polyimide Aerogels Containing Propylene Oxide Links in the Backbone.

Meador MA1, Agnello M1, McCorkle L1, Vivod SL1, Wilmoth N1.

ACS Appl Mater Interfaces. 2016 Oct 12. [Epub ahead of print]

Polyimide aerogels made using anhydride-capped oligomers from 4,4'-oxydianiline (ODA) and 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) cross-linked with 1,3,5-tri(aminophenoxy)benzene (TAB) have been reported with very good mechanical properties but poor resistance to moisture. Replacing 50 mol % of the ODA with poly(propylene glycol)bis(2-aminopropyl ether) (PPG) with an average molecular weight of 230 g/mol in the oligomer backbone gives aerogels with water contact angles of 80°.
