Background: In current polymer nanocomposite fabrication methods such as simple physical mixing and particle surface functionalization a coupling agent/surfactant is required to achieve uniform particle dispersion and provide good bonds between the nanoparticles and the polymer matrix. The chemicals necessary for these functionalization processes can result in high manufacturing costs and complex manufacturing schemes. Technology Description: Researchers at UCLA have identified methods for manufacturing multifunctional polymer nanocomposites containing various fillers including metal and ceramic nanoparticles. The fabrication methods are versatile enough to produce both flexible and robust final products and work with thermoplastic and thermosetting polymer matrix materials. The keys to the method are monomer stabilization and solvent extraction producing a final process that is efficient and environmentally friendly. Applications: 1) Polymer nanocomposite fabrication 2) Industry areas: aerospace electronic devices bio and drug delivery
1) No additional surfactant/coupling agent required to produce high-quality nanocomposite 2) Monomer stabilization eliminates need for solvent during fabrication 3) Solvent extraction method shortens manufacturing time and enables use of metal nanoparticles while protecting them from oxidation
