Title:
PHOTOACOUSTIC EFFECT-BASED METHOD FOR PREVENTING NANOMETER FLUID FROM AGGLOMERATING
Document Type and Number:
WIPO Patent Application WO/2020/244111
Kind Code:
A1
Abstract:
A photoacoustic effect-based method for preventing nanometer fluid from agglomerating. A nanometer gold solution tank (4) is fixed at the tail end of a quartz optical fiber (3), and the quartz optical fiber (3) is placed above a nanometer fluid (5), while a nanosecond pulse laser (1) is turned on, and pulsed laser light penetrates a lens (2), is coupled from the upper end and enters into the quartz optical fiber (3); under laser irradiation, a directional supersonic wave is generated, and photoacoustic conversion is achieved; and the supersonic wave will make the nanometer fluid (5) oscillate, which may effectively prevent nanometer particles from agglomerating. A moving platform drives the quartz optical fiber (3) and the nanometer gold solution tank (4) to move so as to prevent the nanometer fluid (5) at different regions from agglomerating. A CCD is used for real time monitoring, and the moving platform is driven at the right time, thereby effectively, quickly and accurately solving the agglomeration problem of the nanometer fluid (5).
