Title:
DYNAMIC CHARACTERIZATION METHOD FOR MICRO-NANO CELLULOSES
Document Type and Number:
WIPO Patent Application WO/2019/010897
Kind Code:
A1
Abstract:
A dynamic characterization method for micro-nano celluloses, comprising the following steps: (1) performing intermittent ultrasonic processing on micro-nano cellulose suspension liquid; (2) injecting the micro-nano cellulose suspension liquid processed at step (1); (3) adjusting an objective lens of a microscope to ensure that a microfluidic channel is in the field of view of the microscope and the microfluidic channel is a clear imaging; (4) photographing the micro-nano celluloses in the microfluidic channel by using a CCD camera directly connected to the microscope; (5) transmitting pictures photographed by the CCD camera to a computer to process image data, and distinguishing nano celluloses particle from pixel particle of water according to different gray scales between the nano celluloses particle and pixel particle of water on the image; and obtaining important parameters such as length, diameter, velocity, and number of the nano celluloses by using the particle tracking velocity measuring technique according to data processing and analysis of the image photographed by the CCD.
