Abstract
This invention relates to thermosetting inorganic clay nanodispersions comprising an inorganic clay treated in situ with an intercalation agent and a non-aqueous, chemically reactive, organic intercalation facilitating agent, wherein the amount of intercalation facilitating agent is sufficient to facilitate intercalation and to disperse said inorganic clay. The thermosetting inorganic clay nanodispersions comprise an inorganic clay dispersed in an intercalating agent and an intercalation facilitating agent. Thermosetting inorganic clay nanodispersions are used to prepare thermosetting nanocomposite articles.
Claims17
A process for preparing a liquid thermosetting inorganic clay nanodispersion in the absence of water comprising:
- mixing in situ an untreated inorganic clay containing inorganic cations, a quaternary ammonium salt, and a non-aqueous, chemically reactive organic intercalation facilitating agent selected from the group consisting of chemically reactive thermosetting monomers and/or polymers, wherein the amount of intercalation facilitating agent is sufficient to facilitate intercalation and to disperse said inorganic clay.
