Electrostatics can be said to be ubiquitous in our daily life, with very high electrostatic voltages on and around our bodies, thousands or even tens of thousands of volts. Usually can not understand, people walked through the chemical fiber carpet electrostatic is about 35000 volts, read the plastic instructions about 7000 volts, for some sensitive instruments, the voltage may be fatal.

The main research electrostatic applications, such as electrostatic precipitator, electrostatic photocopying, electrostatic biological effects. More important is electrostatic protection technology, such as the electronics industry, the petroleum industry, the weapons industry, the textile industry, the rubber industry and Xinghang Airlines and the electrostatic hazards in the field, seeking to reduce the losses caused by static electricity in recent years with the rapid development of science and technology, micro The widespread application of electronic technology and the increasingly complex electromagnetic environment, the electromagnetic field effect of electrostatic discharge such as electromagnetic interference (EMI) and electromagnetic compatibility (EMC) has become an urgent problem to be solved. On the one hand, some high resistivity polymer materials such as plastics, rubber and other products widely used and the speed of modern production process, making the electrostatic energy accumulation to a high degree, on the other hand, the production of electrostatic sensitive materials and Use, such as light oil, gunpowder, solid-state electronic devices, industrial and mining sector is also more and more harmful to the impact of static electricity, electrostatic hazards have caused quite serious consequences and losses. It can inadvertently break down expensive electronics, causing the electronics industry to lose billions of dollars annually.
