▎ 摘　　要

The proposed technical note is devoted to the study of the fire-retardant properties of a hybrid composite (HC) based on functionalised graphene nanoplatelets (FGNPs) and polybutadiene (PB). The HC was synthesised by the joint of oxidative chlorophosphorylation reaction of FGNPs and polybutadiene and subsequent hydrolysis of the resulting product. To confirm the fire-retardant effect of HC, polyvinyl alcohol (PVA) has been used to form a thin film (HC + PVA) for practical application. Thin films of PVA and HC + PVA were torched with a butane lighter flame and the flammability characteristics were compared. Based on the results, it was determined that the HC imparts fire-retardant properties to PVA. X-ray diffraction phase analysis of HC + PVA before and after combustion was used to explain the combustion mechanism.
