Electrets are materials with a permanent electric dipole moment. This means they have a separation of electric charge within the material, resulting in a permanent electric field.

Oh.. Air Filtration.. got it 😉
How #N95 #Masks 😷block potentially #virus-carrying respiratory blobs via #electrostatic interaction with fibers in the mask created from an #electret (permanently electrically charged) material that polarizes small particles, that are repelled or stuck.⚡️

#Whitesides on #electret, #contact_electrification, @triboelectric_effect. Of his enormous range of interests, electrets and electrification do not rank high, but he has kept returning to the subject. Here is a collection of his papers on electrification: https://t.co/tVLpxSHx2D
I am re-reading the article on #electret by Jefimenko and Walker (1980). It has 16 hand-drawn figures, and describes history, methods of making, applications, and home projects. The history dates back to Stephan Gay (1732). https://t.co/naNWrSO6Ol #electricity #physics
Our purpose is to meet the demand for #meltblown PP materials and #electret #masterbatch all over the world. Therefore, we have recently built a new #meltblownPP material workshop and purchased new production lines. The current output capacity has reached 1200t/day. #nonwoven

If you are a manufacturer of #meltblownfabrics, and you have a demand for #meltblown materials, #electret #masterbatches and #masks, please contact us. https://t.co/N6E7Udm6KG
We can not only supply MFR 800-1800 #homopolypropylene raw material, but also the core additive of melt-blown cloth- #electret #masterbatch.
#Meltblown cloth is mainly made of super-high MI（MFR）polypropylene and the core additive is #electret #masterbatch, whose #fiber diameter can reach 1 ~ 5 microns. The meltblown cloth has many voids, fluffy structure, and good fold resistance.

Coffee break over and time for Reimund Gerhard’s lecture on the global history of international electret symposia!#ise2019 #electret #research #Science #community
Did you Know...
James Edward West improved the #microphone. He built a more #compact and cost efficient #mic by placing #polymer #electret film on one side. Resulting in the conversion of #sound into #high #fidelity #electrical #signals.
