Abstract

A facile and easily industrialized approach for preparing highly dispersed MMT/polymer nanocomposites is developed by combining the latex compounding method and a spray-drying process. Clay particles are successfully delaminated into layers, and layer re-stacking is effectively prevented. HR-TEM and XRD results confirm that MMT layers achieve exfoliated or nearly exfoliated dispersion in both MMT/styrene-butadiene rubber and MMT/PS nanocomposites. Compared with melt-blended MMT/SBR composites, MMT/SBR nanocomposites prepared by this new strategy exhibit extremely high dynamic modulus.
