Abstract

The direct encapsulation of co-valently modified clay platelets by polymers via surfactant-free, starved-feed emulsion polymerization was investigated. It was demonstrated using cryo-transmission electron microscopy (TEM) and scanning electron microscopy (SEM) that small Laponite RD (LRD) platelets were encapsulated inside spherical latex particles, whereas larger montmorillonite (MMT) platelets were encapsulated inside dumbbell-like or snowman-like nonspherical latex particles. The TEM and SEM images show that a considerable amount of spherical particles were present when modified MMT was used for emulsion polymerization. However, It was found using cryogenic TEM (cryo-TEM) analysis that some dumbbell-like or snowman-like particles are free of clay platelets.
