usually ∼30–50 %. The fillers generate stronger elastomers and are of great influence on the thermal stability and flammability composites. Organic and inorganic fillers, such as carbon black or silica, are often added to the elastomers. Usually

Abstract
Heat capacities of the carbon nanotubes (CNTs) with different sizes have been measured by modulated temperature differential scanning calorimetry (MDSC) and reported for the first time. The results indicated the values of C p increased with shortening length of CNTs when the diameters of CNTs were between 60 and 100 nm. However, the values of C p of CNTs were not affected by their diameter when the lengths of CNTs were 1–2 um, or not affected by the length of CNTs when their diameters were below 10 nm. The thermal stabilities of the CNTs have been studied by TG-DTG-DSC. The results of TG-DTG showed that thermal stabilities of CNTs were enhanced with their diameters increase. With lengths increase, the thermal stabilities of CNTs increased when their diameters were between 60 and 100 nm, but there is a slight decrease when their diameters were less than 60 nm. The further DSC analyses showed both released heat and T onset increased with the increase of CNTs diameters, which confirms the consistency of the results from both TG-DTG and DSC on CNTs thermal stability.
application, a critical examination of their thermal stability against the crystallization is very essential. Therefore, there have been considerable attempts to investigate the thermal stability of glassy superionic/amorphous conductors in the last few years
ionic liquids [ 36 ]. Studies presented in this study were aimed at determining thermal stability of hybrid materials based on different epoxy functional siloxanes and (poly)siloxanes crosslinked with various diamines as well as at determining
