Abstract
This cover image by Debjyoti Banerjee and co-authors shows a facile way to ionically cyclize polyacrylonitrile fiber precursors using aldaric acid sugars as anionic initiators. Carboxylate groups in the aldaric acid sugars are responsible for lowering the activation energy barrier needed to initiate the cyclization. This image depicts simulated extended polyacrylonitrile model chains of the fiber microstructure in succession with a cyclization reaction scheme that takes place under high temperatures. The scope of the work has direct applications in the carbon fiber industry. DOI: 10.1002/app.51781
