Exfoliated MMT-PMMA Nanocomposites by Soap-free Emulsion Polymerization

2 Exfoliated MMT-PMMA Nanocomposites by Soap-free Emulsion Polymerization 

The exfoliation of MMT during soap-free emulsion polymerization of MMA has been confirmed by X-ray diffraction. When MMA was polymerized for 

However, it might be argued that the concentration of MMT in 5% MMT-PMMA was too low to provide comprehensible evidence for the exfoliation of 

To answer the second question, sodium dodecyl sulfate (SDS), which carries a similar sulfate ionic group as a model compound, was used to investigate its intercalation with MMT. After mixing MMT with 0.5 and 3 cationic exchange capacity (CEC) of SDS, it was indeed observed that SDS surfactant 

The exfoliated MMT-PMMA latex cannot be cast into film because the Tg of PMMA is well above room temperature. To lower the T of nanocomposites,
