Background
The polymer has the advantages of low price, light weight, high specific strength, small heat conductivity coefficient, good chemical stability and the like, and is widely applied to various fields of production and life. However, most polymers are good electrical insulators, have high electrical resistivity, and are prone to static electricity, thereby limiting their applications. The accumulation of static electricity in human body may affect the normal work of each visceral organ, especially the heart, thereby causing abnormal heart rate and premature heart beat; static electricity on the body can also induce various diseases in the elderly, young, sick, pregnant population. For example, static electricity can cause a decline in maternal hormone levels, which in turn can lead to miscarriage or premature delivery; the static electricity accumulated in children may affect the physiological balance of central nerves and body. Of course, the electrostatic hazard is far more than this. In recent years, along with the development of the electronic industry, the harm of static electricity to human beings is increasing. For example, interfering with the proper functioning of the aircraft radio, thereby affecting aircraft flight; the polymer shell of pharmaceutical factory equipment is easy to adsorb dust due to electrostatic effect, thereby reducing the purity of the medicine; the surface of the television screen adsorbs dust due to static electricity, so that the definition and brightness of images watched by people are reduced.
