Development of polyvinyl alcohol/intercalated MMT composite foams fabricated by melt extrusion

In this work, novel polyvinyl alcohol (PVA)/intercalated montmorillonite (MMT) nanocomposite foams were fabricated by melt extrusion with fixed amount of foaming agent, and the structure and properties were investigated with X‐ray diffraction, transmittance electron microscope, differential scanning calorimetry, plate rheometer, scanning electron microscope, density analysis, and mechanical testing in detail. The results revealed that pristine...
