Fig. 8From: Titanate Nanotubes Decorated Graphene Oxide Nanocomposites: Preparation, Flame Retardancy, and PhotodegradationSEM images of exterior and interior morphology of the residue chars of PVC (a, d) TNTs-PVC (b, e) and TNTs/GO-PVC (c, f) composites. The char of TNTs/GO-PVC was more compact and continuous than that of the neat PVC or TNTs-PVCBack to article page
