Electrophoresis has a broad application area
[ Instrument Network Instrument R & D ] Recently, Zhao Zhigang's group from Suzhou Institute of Advanced Materials, Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences, has published an article entitled Fusing Electrochromic Technology with Other Advanced Technologies: A New A review paper on Roadmap for Future Development.
Electrochromism refers to the phenomenon that certain materials undergo a reversible change in color or optical properties through an oxidation-reduction reaction under the action of an external electric field. It can be used in smart windows, display screens and other fields. In the past forty years, electrochromic technology has made rapid progress; however, due to its limited practical application, its development still faces serious challenges. It is foreseeable that electrochromic technology, as a color control technology that can be read by the naked eye, will have wider applications by applying visualization technology to various functional devices. In fact, some recent research results show that the combination of electrochromic technology with other advanced technologies provides a new and powerful impetus for the further development of electrochromic technology.
Electrochromism is a phenomenon in which the optical properties (reflectivity, transmittance, absorption, etc.) of a material undergo a stable and reversible color change under the action of an applied electric field. In appearance, the color and transparency change reversibly. Materials with electrochromic properties are called electrochromic materials, and devices made with electrochromic materials are called electrochromic devices.
In view of this, this paper systematically introduces the research progress of the integration of electrochromic technology with advanced technologies such as wearable technology, thermal control technology, energy storage technology, energy harvesting technology, and sensing technology. The integration modes, design principles, and performance optimization of different types of electrochromic devices are mainly introduced. Finally, the paper summarizes the current problems of electrochromic devices and looks forward to future research trends.
Electrochromic smart glass has the adjustability of light absorption and transmission under the action of an electric field, which can selectively absorb or reflect external heat radiation and internal heat diffusion, reducing office buildings and civilian residences to stay cool in summer and winter A lot of energy that is warm and must be consumed. At the same time, it has the purpose of improving the natural light level and preventing peeping. Solve the problem of deteriorating urban light pollution in modern times. Is a development direction of energy-saving building materials.
Electrochromic materials have bi-stable performance. Electrochromic display devices made of electrochromic materials not only do not require a backlight, and after displaying a static image, as long as the display content does not change, it will not consume power and achieve Purpose of energy saving. Compared with other displays, electrochromic displays have the advantages of ignoring blind angles and high contrast.
The automatic anti-glare rearview mirror made of electrochromic material can adjust the intensity of the reflected light according to the intensity of external light through the electronic induction system to achieve anti-glare effect and make driving safer.
Electrochromic smart glass can adjust the light intensity inside cars and airplanes with lower voltage (2-5V) and lower power, making the journey more comfortable. At present, electrochromic light glass has been used in some high-end cars and aircraft.
