Improving charge storage capacity of Electret Materials

2021.07.17storage capacity of electret materials

  To increase the charge, the electret can be used. To store the static electricity, the composition and structure of the material should be used to keep the charge. There are two ways for electret masterbatch to improve the charge storage capacity of Electret Materials

  1. By improving the crystallinity and mechanical deformation of the material, the structure of the material changes, forming slender holes to prevent charge drift.

  2. By introducing additives with charge storage properties, charge traps are generated to capture charge.

  Therefore, there are two types of electret masterbatch

  1: Change the crystallinity and mechanical deformation of PP materials, such as crystallization related additives. Here you can also understand why the melt blown die is very important, because the die directly affects the micro morphology of non-woven fabrics.

  Tourmaline Name: tourmaline, commonly known as tourmaline, Bisi, also translated as tormaline, because tourmaline has thermoelectricity and piezoelectricity, easy to be charged due to electrostatic effect, hence the name.

  2: Introducing charge storage, such as adding tourmaline masterbatch with nano electrode. Because these two types of electret masterbatch are very different in addition and price.
