Fillers dispersion thermal analysis

Abstract A CaCOs filler was coated with various mono- and dicarboxylic acids in a dry-blending process. The coated fillers were characterized by various techniques, including dissolution experiments, thermal analysis (differential scanning calorimetry) and inverse gas chromatography (IGC) to determine the amount of surfactant needed to achieve mono-layer coverage IGC proved to be the most convenient, reliable and universal method for this purpose. The dispersion component of the surface tension and the specific interaction potential of the coated filler can be derived from the results, but indirect conclusions can be also drawn from them about the orientation of the molecules on the filler surface and the structure of the layer formed. The coverage of the filler with an organic compound leads to a... 

Differential scanning calorimetric (DSC) analysis has been widely used in examining the effect of various fillers in SR on thermal transition such as glass transition (T, melting points (T ) and crystallization temperature (T ). According to Katihabwa et al. [179], T of pure silicone rubber (-71.87°C) increases in the presence of 1, 5,10, and 20 wt% of CNT loading to -68.67, -64.91, -63.21 and -63.57 C, respectively. This is due to the presence of dispersed CNT,...
