Abstract Smoke hazard is the main murderer to human life during a fire hazard of polymer-based materials. Thus zinc hydroxystannate-titanate nanotube (ZHS-TNT) flame retardant with sugar-coated haw-like microstructure was prepared by a facile in-situ solution method in order to suppress the smoke release of flexible polyvinyl chloride (PVC). Findings indicate that ZHS-TNT contributes to enhancing the flame-retardancy and smoke suppress properties of PVC and is superior to mechanically mixed ZHS and TNT. The limiting oxygen index is enhanced from 25.8 of pure PVC to 29.6 of PVC composite filled with 2.5 wt% ZHS-TNT, and the total smoke release and average specific extinction area are decreased by 40% and 34%, respectively. This is ascribed to the synergistic flame-retardant effect of ZHS and TNT.
