Challenges of Thermal Degradation in Melt Intercalation

Polycarbonate nanocomposites were prepared by melt compounding and the effect of organoclay structure on color formation was examined. Darker colored nanocomposites were obtained for samples containing the organoclay with double bonds in the hydrocarbon tail, compared to those with saturated organic modifiers. The presence of both hydroxy-ethyl groups and tallow tails led to the most important color changes [19]. 

Scaffaro and coworkers [20] prepared PET nanocomposite using a twin-screw extruder. The intrinsic viscosity of the neat PET and extruded PET was reported to be 0.83 and 0.82 dL/g, respectively, while PET nanocomposites containing 10wt% C30B exhibited an intrinsic viscosity of 0.63 dL/g (see the discussion on intrinsic viscosity measurements of nanocomposites in the next paragraph). This remarkable reduction in
