TLDR
In this article, a bidentate linkage is formed between an acidic aluminum and two oxygen atoms of an acetal unit of Fomblin Z chains, and the partial positive charge thus developed at the acetal carbon induces a fluorine atom transfer from the adjacent CF2 unit onto theacetal carbon and results in chain scission with transformation of the entire chain into either an acylfluoride end-group (FCO-CF2-O) or a fluoro-formate endgroup (FO-O)-group.About:

Activating Aluminum Reactivity with Fluoropolymer Coatings for Improved Energetic Composite Combustion
TL;DR: This study investigates a perfluorinated polymer additive, PFPE, incorporated to activate Al reactivity in Al-CuO and Al-MoO3 and shows that the performance of the thermite-PFPE blends is highly dependent on the bond dissociation energy of the metal oxide.
