 Energy conversion and ignition of fluffy graphene by flash lightGuannan Liu, Dong Liu, Junwu Zhu, Jili Wei, Wei Cui and Shuiqing Li Energy, 2018, vol. 144, issue C, 669-678 Abstract: Graphene has been subjected to widespread attention, and its highly extraordinary properties have led to abundant scientific researches. The present study shows that fluffy graphene can ignite in a fairly short time upon exposure to a conventional flash light, even in an extremely low temperature environment. The ignition process is fierce and multi-points are distributed with temperatures as high as 1840K with few residues. This kind of ignition can be attributed to the graphene nanostructure efficiently converting light to heat and causing a large amount of heat to accumulate within a very short flash time with the temperature quickly exceeding the ignition point. It is further demonstrated that graphene can ignite in an environment as low as about −50 °C. When fluffy graphene was added to extremely lean methane/oxygen/nitrogen mixtures, ignition of the mixtures was successfully triggered by flash light. The ignition characteristics make graphene a promising alternative for ignition fields in harsh environment.
