Embodiment 1

[0024] Embodiment 1: Nanoparticle adhesion detection method, described method comprises the steps:

[0025] 1) Through ion sputtering technology, metal gallium is used as the target material, and a layer of 50nm-1000nm thick metal gallium film is coated on the underside of the needle-free cantilever of the AFM adhesion detection probe;

[0026] 2) The nanoparticles to be tested are firstly added to the sample of the particles to be tested in absolute ethanol, ultrasonically dispersed for 5-45 minutes, and part of the dispersed upper layer liquid is dropped on the sample holder, dried to obtain the nanoparticles to be tested, and used a double-beam electron microscope Observe the appearance of nanoparticles on the sample holder by SEM in , here select a particle with a particle size of about 600nm, to prevent the nanoparticles from being coated with liquid metal gallium due to the infiltration of nanoparticles and liquid metal gallium;

[0027] 3) Fix the nanoparticles on the A...

Abstract

The invention discloses a method for detecting the adhesion force of nanoparticles. The present invention prepares the AFM probe tip adhered with specified nanoparticles to accurately detect the adhesion force between a single particle and the interface to be tested, and eliminates the uncertainty of the shape of the nanoparticles and the surface tension caused by the water molecule layer on the measurement. To ensure the accuracy and authenticity of the measurement results. The invention is simple and easy to implement, low in cost and good in use effect.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, and in particular relates to a method for detecting the adhesion force of nanoparticles. Background technique [0002] Adhesion is an important physical characteristic of dust particles, which is widely used in scientific research and industrial production. Adhesion refers to the ability of a material to adhere to the surface of another material. Attachment materials generally refer to liquid or powdery solids, and attached objects refer to objects with a certain surface. Paint and glue are common adhesive materials. The size of the adhesion depends not only on the molecular structure and chemical composition of the adhered material, the surface characteristics of the adherend, but also on the external conditions of the adhesion, such as temperature, humidity, radiation, vibration, wind speed, etc. . [0003] As early as the last century, there were reports on the detection metho...
