Ti-Graphene Reactive Interaction at Elevated Temperature

The reactive interaction between titanium (Ti) and graphene is an area of interest in materials science and nanotechnology. While titanium and graphene have very different properties, there are potential applications for Ti-Graphene system and reactive interactions worth to explore. In this presentation we will discuss several aspects of the Ti-Graphene reactive interaction, including activation and self-sustain reaction behavior. Differential scanning calorimetry was used to characterize reaction features for titanium particles and graphene nanoflakes under heating rate at 20 °C min^-1. The visible reaction of Ti-Graphene system was observed at 596 °C with 39 J/g energy release. This confirms exothermic behavior of the reaction. The exothermic reaction between titanium and graphene within the confines of MWCNT was observed at 595 °C results in the generation of 50 J/g of released heat. This denotes a roughly 28 % increase in heat discharge compared to the exothermic reaction where only pure titanium and graphene are involved. Analytical examination confirmed the presence of TiC nano phase inclusions within the MWCNT yarns.
