Abstract:This study prepared layered intumescent flame retardant (IFR)‐graphene oxide (GO) via the esterification of GO and IFR. Then the distribution of IFR‐GO in polybutylene terephthalate (PBT) was regulated via an injection molding process, while the tensile strength and combustion were explored. The results showed that the flame retardant distribution in PBT presented high external concentrations and low internal concentrations when the injection time was reduced. The lowest flame retardant content of 20 wt% was e… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
