Method and apparatus for dispersing small particles in a matrix

Abstract

An apparatus for dispersing particles (e.g., nanoparticles) in a matrix includes a container (11), an agitating device (12), an ultrasonic vibrating device (15), a heating device (18), and a holder (19). The container is configured for containing the particles and a surfactant (22), while the agitating device is adapted to extend into the container and is thus configured for agitating the particles with the surfactant. The ultrasonic vibrating device is connected to the container and is able to receive a mixture of the particles and the surfactant. The ultrasonic vibrating device is configured for sufficiently dispersing the particles in the surfactant to form a dispersion. The holder is configured for receiving a fluid (i.e., the dispersion) from the ultrasonic vibrating device and for retaining a matrix material therein. The heating device is configured for evaporating the surfactant.
