Preparation and porous control of amorphous carbons by co-defluorination of perfluorooctane and octafluorotoluene in vapor phases at 423 K

Synergistic effects induced by oxy-fluorination of carbon preforms to improve the mechanical and thermal properties of carbon–carbon composites

“…In this case, C-F bonds just work for improved impregnation of the phenol carbon matrix precursor due to the improved affinity of carbon fiber to the phenol, resulting in the densified C/C composites after carbonization. It is generally believed that the C-F bonds start to be broken above 300 8C [27]. And after C-F bond breakage, all of the two reactions can occur.…”
