Anti-static material is a special functional material that can effectively reduce or eliminate the accumulation of static electricity. Static electricity is a phenomenon that occurs due to an imbalance of charges on the surface of an object, usually during friction, separation or contact. For materials such as paper and plastics, static electricity problems can lead to dust adsorption, handling difficulties, product quality degradation and even safety hazards. Therefore, the development and use of antistatic materials has become an important means of solving these problems.

Anti-static materials for paper and plastics are usually realized by adding conductive substances (e.g., antistatic agents, carbon nanotubes, metal oxides, etc.) to their surfaces or interiors. These materials are able to reduce the surface resistivity, so that static electricity can be quickly dissipated, thus avoiding the negative effects of static electricity accumulation.

The features of anti-static materials are:

  1. Excellent conductive properties
    1. The core feature of anti-static materials is that they have a certain degree of conductivity, which can quickly conduct static electricity to the ground or other conductive media, thus preventing static buildup.
    2. The surface resistivity is usually between 106~1012 ohms, depending on the needs of the application scenario.
  2. Persistence
    1. Certain antistatic materials (such as permanent antistatic agents) are able to maintain stable antistatic properties over a long period of time, and are not prone to failure due to changes in the environment or prolonged use.
    2. Some temporary antistatic coatings, on the other hand, may require regular maintenance or re-treatment.
  3. Environmental protection and safety
    1. Modern antistatic materials pay more and more attention to environmental protection and safety, using non-toxic, harmless, biodegradable components, in line with green environmental protection requirements.
    2. No irritation to human body and environment, suitable for food packaging, medical supplies and other fields.
  4. Strong adaptability
    1. Anti-static materials can be customized according to different materials (such as paper, plastic film, foam, etc.) to meet diversified needs.
    2. It can maintain good anti-static effect under high temperature, low temperature, high humidity or dry environment.
  5. Convenient processing
    1. Anti-static materials can be processed by spraying, dip coating, extrusion molding, co-mingling and other ways, easy to combine with the existing production process.
    2. It can be directly added to the plastic substrate as an additive or applied to the paper surface as a coating.
