| There has been growing interests in nanoparticle-filled polymer composites. In this work, a green chemistry approach was applied for polymer/inorganic nanocomposite synthesis via in-situ polymerization in scCO2. Monodisperse silica nanoparticles were synthesized and surface-modified with MPS as filler material. After initiation, surface grafted MPS were copolymerized with monomer MMA on nanoparticle surface. Analysis of the end products showed that silica particles were well dispersed and embedded into the large polymeric particle matrix, forming an ideal nanocomposite material. It was found that surface modification of silica particles played a key role in improving the compatibility between silica and PMMA. Nanoparticles and PMMA were bonded together through MPS molecules on silica surface. The morphologies of final composite were controlled by varying operating conditions, such as particle to polymer ratio, surfactant concentration. Characterization techniques include SEM, TEM, EDS, TGA, etc. Recent results showed that this approach could be applied to many other inorganic nanoparticles and polymers. |
