State of Development The methods have been used to manufacture high-quality nanocomposites and some have been used for device exploration 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. Tech ID/UC Case 20420/2008-452-0 Related Cases 2008-452-0
