Abstract

Nanoclay reinforced polymer blends exhibit high potential as a new material for CO₂ foaming because they can provide higher CO ₂ solubility, lower gas diffusivity, and better mechanical properties than foams made of homopolymers. In this paper, a polystyrene (PS)/poly(methyl methacrylate) (PMMA)/nanoclay blend was selected to study the relationship among blend morphology, nanoparticle distribution, and foam structure. PMMA serves as the dispersed domain in PS. Blends with different morphology were obtained by changing the nanoclay content and the screw configuration, which were then foamed by using CO₂ in a batch system. Effects of nanoclay content on the blend morphology, rheological properties, and foam morphology were studied. It is found that the highest foam nucleation efficiency appears at the interface of PS/PMMA/nanoclay.
