A dielectric is an insulator
that can be polarized.
It has a very low electrical conductivity, but has good dielectric strength, and is an ideal material
for the manufacture of electrical insulators.
The latest issue of Nature magazine introduces a new polymer dielectric, which can not only store energy, but also has good high temperature resistance, and has a wide range of application prospects
in the manufacture of hybrid vehicles, pure electric vehicles and spacecraft.
Since the dielectric can be highly polarized, it is also very suitable for the manufacture of capacitors
.
Capacitors made of dielectrics are used in a wide range of applications in
electronics and power supply systems.
However, the vast majority of polymer dielectrics were sensitive to temperature and could only work normally
at lower temperatures.
In the new study, Wang Qing, a researcher at Pennsylvania State University in the United States, and his research team used a polymer hybrid material containing a boron nitride nanofilm to create a new high-temperature resistant dielectric
.
This new material not only surpasses the existing polymer dielectric in energy storage characteristics, but also can withstand a certain high temperature, even at a high temperature of 250 degrees Celsius
.
According to reports, the new polymer dielectric also has lightweight, patternable and high flexibility, and can still maintain good performance
after repeated bending.
The researchers said that this new material may change the construction process of dense energy modules and power circuits under extreme conditions, and has important value
for the manufacture of equipment with strict temperature and weight requirements.
