ESD (Electrostatic Discharge)
Published in Jack Arabian, Computer Integrated Electronics Manufacturing and Testing, 2020
From the above discussion, in order to slowly drain off electrostatic charges from a plastic or similar surface with high resistivity, it is desirable to increase the conductivity of that surface slightly by reducing the surface resistance: not enough to be fully conductive, but enough to be “static dissipative.” The early literature (see Reference 4-10) describes an “antistatic agent” as a liquid which can be either dipped, sprayed, printed, or wiped on a surface or impregnated in the material to accomplish the desired results. The stated purpose of the antistatic agent was to create a layer of moisture, which makes the surface more conductive. Recently, however, the role of the antistatic agent, or “antistat” has been redefined by the IS-5A (Reference 4-09) specification:

Antistatic agents are chemicals that are used to treat the material surfaces in order to eliminate or minimize the buildup of static electricity which is generated due to the triboelectric effect or any noncontact process. The function of antistatic agent is to make the material’s surface itself slightly conductive. As we know that polymers are insulators in nature and hence, get static electricity. Ionic liquids serve the purpose effectively on plastics, floors, and wood.25, 26, 27

The textiles antistatic property is a critical indicator for protective materials. The electrostatic effect in protectives can enable airborne dust and particles to be easily adsorbed to the surface, which increases the risk of exposure and infection to the wearer. Therefore, anti-static finishing and anti-fouling finishing are equally important in protective materials (Wang, 2009). The antistatic property result is displayed in Figure 10. The frictional charge of SMS decreases with the finishing concentration. When the antistatic agent concentration was above 7.5 g/L (F-30), the frictional charge changed less. This result indicates that the antistatic agent is able to form stable adsorption on the fiber surface to improve fiber conductivity and reduce the charge accumulation (Shi et al., 2018).
