  • High Shear Thin Film Machine For Dispersion and Simultaneous Orientation-Distribution Of Nanoparticles Within Polymer Matrix
    Publication number: 20220032245
    Abstract: An improved a device and method for dispersion and simultaneous orientation of nanoparticles within a matrix is provided. A mixer having a shaft and a stator is provided. The shaft may have a rupture region and erosion region. Further, an orienter having an angled stationary plate and a moving plate are provided. The nanoparticles and the matrix are fed into the mixer. A rotational force is applied to the shaft to produce shearing forces. The shearing forces disperse and exfoliate the nanoparticles within the matrix. The dispersed mixture is outputted onto the moving plate. The moving plate is forced across the angled stationary plate to produce fully developed laminar shear flow. The fully developed laminar shear flow or the two-dimensional extensional drag flow orients the dispersed nanoparticles-matrix mixture.
