Measurement device and method for measuring bonding force between solid and liquid interfaces under electric field

Abstract

The invention discloses a measurement device and method for measuring a bonding force between solid and liquid interfaces under an electric field. The measurement device includes a transparent plasticoperating cabinet, a horizontal base, a laser sensor, an electric displacement platform, a cantilever beam, a high-speed camera, a support frame, a power source and a data control processing terminal. During measurement, with slow movement of the electric displacement platform, under the action of a bonding force between the cantilever beam and liquid drops, the cantilever beam is deformed, specific values indicating the deformation degree of the cantilever beam in an experiment are recorded by the laser sensor, and then the bonding force between the solid and liquid interfaces under the electric field can be calculated. Meanwhile, the high-speed camera is used for photographing the whole experiment process and recording the changes of contact angles and contact areas of the upper and lower surfaces of the liquid drops. A measurement system has the advantages that the operation is simple, the cost is low, the application range is wide, and the measurement precision is high. Requirements for measuring the bonding force between the solid and liquid interfaces under the electric field can be well met.

AI Technical Summary

Benefits of technology

This patented technology allows for precise measurement of various physical properties by measuring small force on tiny samples that have been treated with specific chemicals or liquids during testing. It also simplifies the production processes while maintaining their accuracy over long periods of use. Additionally, it provides an efficient way to conduct researches based upon these measurements.

Problems solved by technology

Technologies aimed at understanding how solid surfaces behave during their interactions with liquids have developed over time due to changes made upon them' physical characteristics (such as shape) caused by external forces like electrodes applied thereon. These techniques include observation of static and dynamic behaviors of solvophils and sputterings, analysis of electronic signals, manipulation of materials called molecules, magnetic attraction, ion transfer, atom motion, flow dynamics, chemical reactions, and others. To address these challenges, advanced mathematical models were proposed based on specific principles and thresholds.
