Glavier L, Taton G, Ducéré J, Baijot V, Pinon S, Calais T, et al. Fluorination yields heat feedback to the reactive surface, thus providing the main advantage of aluminum–fluoropolymer reactive system for energy release. The initial decomposition products of Viton would be induced to form more cyclic hydrocarbon by the fluorination of nAl with gaseous fluorocarbons and hydrogen fluoride released from Viton decomposition. Results show a direct correlation between the nAl particles and the relative abundance of products. Temperature jump experiments were used to confirm the occurrence of interfacial reactions between nAl particles with the products produced by Viton decomposition, and the gaseous products of during the reactions were investigated via online gas chromatography/mass spectrometry. The oxide shell of nAl underwent a pre-ignition reaction with Viton before Viton decomposition, followed by the reaction of nAl with the products from Viton decomposition, and defluorination of aluminum fluoride. The results under slow heating rates indicate that composites reacted in several stages at 100–1000 ☌. The interfacial reaction of nano-aluminum (nAl) and fluoropolymer was evaluated using composite under slow and rapid heating rates.
