Surface chain cleavage behavior of PBIA fiber induced by direct fluorination
Source abstract
Abstract
Abstract The surface chain cleavage behavior of PBIA fiber induced by direct fluorination was reported based on the analysis of physical and chemical changes on the fiber surface. The chain cleavage product was obtained to evaluate the chemical reaction during the fluorination process, and its impact on composites performance was also involved. DSC, FTIR spectra, UV–vis absorption spectra and H 1 NMR were utilized to analyze the chemical structure and composition of the chain cleavage product. The results show gaseous fluorine is most likely to attack the benzimidazole and amide bond in PBIA unit, which was also demonstrated by molecular simulation. Owing to the polar groups contained in chain cleavage products, the wettability of epoxy resin to fiber has been improved, leading to an 11.5% increase of adhesive strength of fiber-epoxy composite.
