【 摘 要 】

The synthesis of ultrafine MoO₃ through a self-propagating combustion route employing polyethylene glycol as fuel is reported. The precursor molybdenum oxalate is employed in this study for the conversion of the precursor to ultrafine MoO₃ particles. The solvent casting method is adopted for the synthesis of MoO₃ dispersed polyvinyl alcohol nanostructured film (MoO₃â€�?�PVA). These synthesized MoO₃ and their composite samples are characterized for their structure, morphology, bonding and thermal behaviour by XRD, SEM, IR and DSC techniques, respectively. The distribution of MoO₃ in polyvinyl alcohol gives a crystalline polymer, a compact structure and an increase in glass transition temperature.
