What are anti static polymer?

Antistatic polymers are polymer materials that prevent the accumulation of electrical charges on objects. It can achieve antistatic effects in a variety of ways, such as adding conductive fillers, using antistatic agents, or blending with structural conductive polymers.

Generally speaking, when the surface resistivity of an antistatic polymer is between 10E9 and 10E12Ω, it has antistatic ability. In practical applications, antistatic polymers are mostly composite materials with conductive layers on the surface or filled with conductive fillers. These materials are widely used in situations where dust and gas explosions need to be prevented and precision electronic instruments are manufactured and used.

Classification of antistatic polymer

  • Anionic antistatic antistatic polymers: mainly include alkyl sulfonates, phosphate ester salts, sulfate ester salts, etc. They achieve an antistatic effect by forming a conductive layer on the polymer surface to reduce surface resistance.
  • Cationic antistatic antistatic polymers: Common ones include quaternary ammonium salts, pyridinium salts, etc. This type of antistatic agent interacts with anions on the polymer surface to form ionic bonds, which increases the conductivity of the polymer surface and reduces static electricity accumulation.
  • Zwitterionic antistatic antistatic polymers: contain both cationic and anionic groups in their molecular structure. This antistatic antistatic polymer can function in different pH environments and has good stability and antistatic effects.
  • Nonionic antistatic polymers: mainly include polyols, polyethylene glycols, fatty acid esters, and other polymers. They reduce surface resistance by forming a hygroscopic film on the polymer surface that absorbs moisture from the air.

When selecting an antistatic polymer, factors such as the type of polymer, processing conditions, application environment, etc. need to be considered to ensure that the antistatic polymer can function effectively and will not have a negative impact on the antistatic performance.

Factors affecting the antistatic effect of polymers

  1. Type and dosage of antistatic agents: Different types of antistatic agents have different effects. Too much or too little dosage will affect the antistatic performance.
  2. Properties of the polymer: The structure and polarity of the polymer itself have a certain impact on its antistatic effect.
  3. Ambient humidity: Antistatic effects tend to be better when the humidity is higher, because moisture helps conduct and dissipate charges.
  4. Processing conditions: Such as processing temperature, shear force, etc. will affect the dispersion and distribution of antistatic agents in the polymer, thus affecting the antistatic effect.
  5. Compatibility of antistatic agents and polymers: Poor compatibility may lead to problems such as migration and precipitation of antistatic agents, affecting the durability of the effect.
