Inorganic Antiflaming Wood Caused by a TiO2-Decorated ZnO Nanorod Arrays Coating Prepared by a Facile Hydrothermal Method

الملخص EN

Wood materials with antiflaming capability were successfully fabricated by depositing a TiO2-decorated ZnO nanorod arrays (ZNAs) film on wood surface using a facile and one-pot hydrothermal method.

The prepared specimens were characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), and powder X-ray diffraction (XRD).

To explore the antiflaming properties, the combustion parameters of the wood treated by TiO2-decorated ZNAs were measured using the cone calorimetry technique compared with the untreated wood.

For treated wood, the burning duration was prolonged for 55 s; smoke production rate (SPR) and total smoke production (TSP) were obviously reduced, especially for the production of CO was almost zero.

As a result, thin inorganic film of TiO2-decorated ZNAs had desirable fire resistance, and one-pot hydrothermal method was a feasible method to fabricate nonflammable wood materials.
