INVESTIGATION ON THE THERMAL DECOMPOSITION AND THE MORPHOLOGICAL PROPERTIES OF CRYOGENICALLY TREATED MWCNTs

摘要

Carbon nanotubes being a major vital role player in nanocomposites, due to their versatility and ability to improve and enhance the properties of the matrix which is used in the composite, it is necessary to study the properties and the changes of the morphology in the carbon nanotubes with respect to different working conditions. Since nano composites were widely used in aerospace applications, where the thermal cycles are very extreme. So, it is necessary to study the change in morphology and properties of the carbon nanotubes after introduction in these extremities. This research on carbon nanotubes involves the cryogenic treatment of carbon nanotubes at 77K (Cryogenic Temperature) followed by the study of the morphology by Field emission Scanning electron microscopy, thermal decomposition by DSC/TGA till the temperature of 550°C and analyzing the XRD results and comparing the results with that of untreated carbon nanotubes.
