T1 - Carbon black, multiwall nanotubes and graphene - promising approach to flame retarded nanocomposites? N2 - Carbon black (CB), multiwall carbon nanotubes (MWNT), expanded graphite, multilayer graphene and graphene were used and compared as adjuvant and flame retardants in nanocomposites with respect to different fire scenarios. During the anaerobic pyrolysis feeding the flame, the investigated carbon additives acted as inert fillers. They formed residual protective layers, reducing the peak heat release rate in particular. The efficiency of the protection layer was dependent on the particle dispersion within the nanocomposite. However, other nanocomposite properties also influence the complex fire behavior crucially, including viscosity, thermal conductivity and the depth of heat absorption. Induced flow limits influence the melt flow, dripping behavior and thus the flammability (reaction to small flame) monitored by OI and UL 94. Increased thermal conductivity and depth of heat absorption change the time to ignition. Structure-property relationships are described as a basis for deducing guidelines for future flame retarded carbon particle nanocomposites.
