Abstract
We successfully synthesized GexSe1-x (x = 0.225) glass samples and doped the samples with commercially produced (Protein Mods) carbon nanotubes (CNTs). We investigated the glass transition temperature (Tg) using Modulated Differential Scanning Calorimetry (MDSC). The glass samples without the CNTs have a Tg of ~220°C and the Tg was found to be independent of starting materials from different suppliers as well as water-bath temperature. CNTs, being a very hygroscopic material as well as oxygen absorbing material, needed to be cleaned under vacuum with the hot water-bath. We found that the Tg decreases when 5% and 10 % CNTs by mass is added to the glass samples as compared to the base GexSe1-x glass. The decrease in Tg indicates the occurrence of an intermediate phase (reduced-stress glass phase) at lower temperature, which could be potentially useful in material science applications.
