Handling of Nanoparticles
The Composites and Plastics Lab uses different types of industrial nanoparticles such as nanoclays and Hollysoite Nanotubes; and engineered nanoparticles such as carbon nanotubes. These dry nanoparticles are dispersed within liquid thermoset resins using different mixing techniques such as high-shear mixer, sonication, centrifugal mixer, and low-shear mechanical mixer. These nanomodified resins are further used in composite manufacturing processes such as vacuum infusion and compression molding.
Special care is taken while handling and storing dry nanoparticles. Handling dry nanoparticles in open atmosphere is not allowed. Two methods have been developed to handle dry nanoclays and dry carbon nanotubes.
