Abstract

The invention discloses a system and method for measuring the micron size area temperature of graphite within a room temperature range and a visualization algorithm. The system comprises a to-be-measured graphite sample made sheet, a digital microscope, a displayer, a temperature-adjustable temperature control table, a mouse, an external storage device and a computer. Cholesteric phase liquid crystal testing liquid is dropwise added onto the to-be-measured graphite sample made sheet, the to-be-measured graphite sample made sheet with the dropwise added cholesteric phase liquid crystal testingliquid is flat placed on the temperature-adjustable temperature control table, a lens of the microscope is suspended above the to-be-measured graphite sample made sheet with the dropwise added cholesteric phase liquid crystal testing liquid, the microscope is connected with the mouse, the external storage device and the displayer through data lines, thus an operator can capture images in the viewfield of a specific microscopic area, and the images are shot and preserved. According to the technical scheme, by applying the temperature-sensitive characteristics of cholesteric phase liquid crystals, the heat conductivity of the graphite and a computer image processing technology, an accurate, convenient and rapid solving scheme is provided for researching of the thermal characteristics of thegraphite.

Description

technical field [0001] The invention relates to a system for measuring the temperature of graphene in a micron-sized region within a room temperature range, a method thereof and a visualization algorithm, and belongs to the field of application research of temperature-sensitive cholesteric liquid crystals in graphene thermal properties. Background technique [0002] With the development of the times, electronic devices and solid materials are developing towards refinement. Among them, temperature is a parameter that cannot be ignored in the research process. Graphene is a brand-new heat conduction and heat dissipation material, which has a unique grain orientation and conducts heat evenly in two directions. Its layered structure can be well adapted to any surface. , biomedicine have great prospects. However, in the study of thermal properties of graphene, traditional measurement methods cannot meet the needs of measurement accuracy and measurement area (for example, it is d...

Problems solved by technology

However, in the study of thermal properties of graphene, traditional measurement methods cannot meet the needs of measurement accuracy and measurement area (for example, it is difficult to measure the thermal effect of the device on the micron scale by the previous method).

[0003] Usually, people use infrared thermometers for temperature measurement, but the minimum area of ​​the measurement point of this temperature measurement method is still relatively large
