Abstract

The investigations of the nanostructured-Al (nano-Al) based thermo-oxidative reaction attributes are detailed in this chapter-5. Two products are selected for the thermo-oxidative reaction studies. They are (1) Nano-Al embedded in the PVP matrix (will be termed as fuel) and (2) its physically mixed 1:1 stoichiometric nanocomposite processed with the ultrafine nc-ceria oxidizer (also will be termed as nanoenergetic material (NEM)), respectively. The graphical abstract presented below illustrates an overview of the thermo-oxidative reaction of fuel tracked employing thermogravimetric analysis (TGA) investigation. Similar TGA experimentation of the designed NEMs is carried out to gather scientific information validating, whether or not a desired enhanced attribute is achieved. Also, in coincidence with the TGA oxidation event, a synchronous exothermic energy release event in differential scanning calorimetry (DSC) trace is observed. The above mentioned two products and their thermo-oxidative reaction behavior employing TGA/DTA and TGA/DSC thermal traces are compared and interpreted based on the data available in the literature.
