The performance of poly(carbon monofluoride) (PMF) (synonym: graphite fluoride) (CFx)(n), (1) as oxidizer in a fuel rich Mg based pyrolant (xi(Mg) = 0.45) is investigated. The radiance [W sr(-1)] under both static and dynamic conditions, the spectral radiant exitance [W cm(-2) mu m(-1)], the linear burn rate [mm s(-1)] and the mass consumption rate [g s(-1) cm(-2)] have been determined. Calculations for enthalpy of anaerobic and aerobic combustion [kJ g(-1)] and for the equilibrium composition of the combustion products as well as combustion temperature are given. A mechanism for the reaction is discussed. The combustion product from Mg/(CFx)(n) surprisingly reveals the formation of single walled carbon nanotubes (SWCNT) and "carbon nano carpet rolls" (CNCR).
