Abstract

Macroporous monoliths consisting of silica nanoparticles embedded in poly(metnyl methacrylate) (PMMA) were synthesized in supercritical CO ₂. Well-dispersed silica particles, pretreated with functional 3-(trimethoxysily1)-propyl methacrylate (MPS), were to form colloidal PMMA nanocomposites followed by a sol-gel transition forming interconnected structures resulting in micron-sized pores with specific areas between 1 and 7 m² · g^-1. SEM and TEM results revealed uniform morphological characteristics of the composite materials and good dispersions of the silica nanoparticles.
