A unique approach is to exfoliate clay in carbonaceous precursor like starch, and to convert the starch to carbon soot. Exfoliated clays in soot are low-cost dual composites that exploit the high modulus plates of clay in soot as the reinforcing agent while the surrounding amorphous soot acts as the dispersant into a polymer matrix.
The paper wil describe the creation of these composites with regards to the clay types and their loading on creating well-exfoliated composites. Clays such as Laponite, Montmorillonite are shown to be well exfoliated within the starch matrix and subsequent to the carbonization process, in the soot. Some aspects of dispersion into polymers and their attendant properties will also be described.
