Device for measuring liquid absorption coefficient under condition of external electric field

Abstract

The invention discloses a device for measuring the liquid absorption coefficient under the condition of an external electric field. The device comprises an incident light source, a sample pool, a power supply, electrode plates and a measuring unit, wherein the sample pool is of a transparent rectangular structure; in addition, the thicknesses of each side edge are equal; the electrode plates comprise a first electrode plate and a second electrode plate which are mutually parallel; the first electrode plate is fixedly arranged at the inner side of the first side edge of the sample pool and is connected with the positive electrode of the power supply; the second electrode plate is fixedly arranged at the inner side of the second side edge of the sample pool and is connected with the negative electrode of the power supply; the incident light source is arranged at the outer side of the third side edge of the sample pool; generated incident light rays are incident along the direction vertical to the electric field through a light transmission hole formed in the third side edge; the measuring unit is arranged at the outer side of the fourth side edge of the sample pool and is positioned on a light path of the incident light rays; the third side edge and the fourth side edge are mutually parallel. The device has the advantages that the electrode plates are arranged in the sample pool; the uniform electric field can be exerted on liquid to be tested, so that the change of the liquid absorption coefficient under the effect of the external electric field is accurately measured.

Description

technical field [0001] The invention relates to the field of physical parameter measurement, in particular to a device for measuring liquid absorption coefficient under the condition of an external electric field. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Electrorheological fluids or ionic liquids will have a certain change in the absorption coefficient of light under the action of an external electric field. This characteristic can be applied to fields such as electrochromism, smart glass or stealth materials. In terms of building energy saving (for example, adjusting the transmittance of sunlight according to needs in different seasons and climate changes to reduce heating and cooling losses) and protecting personal privacy (for example, in some public facilities such as public telephone booths, change ...

AI Technical Summary

Problems solved by technology

Summarizing the existing reports, it can be found that almost all of the existing studies measure the absorption coefficient of liquids under normal conditions, and there is no report on how to measure the absorption coefficient of this type of liquid that changes the absorption coefficient under the action of an applied electric field.

For special media such as electrorheological fluids or ionic liquids, whose absorption coefficient will change under the action of an applied electric field, there is no design scheme and inversion method for the absorption coefficient measurement device.
