The only problem I have with this video is, When you call a Cellular phone and if it's out of reach OR Airplane mode OR turned off, the "calling phone" does not sound a "Ringing" tone. Not even a Lead box does not block the signal. and if there is such a fabric I don't think it will be available for the general public in this "surveillance society".

[@paluszakmarc8236]

hello, I would like to test this product. Do you have a link for the purchase. The frequencies covered by the description from 8 to 12 GHz are not those used in telephony.

[@Godsmessenger333]

Does this MXene coated material block off electromagnetic waves in the ELF range? I’d like to see a demonstration if that’s possible. Humanity is in trouble

[@gkgkgk7954]

I think so, too. About your opinion of Elf

[@RonPaulOrDie]

Will this be available to the general public?

[@a.j.drexelnanomaterialsins5931]

Millipore Sigma and other providers are offering various MAX phases for purchase. Soon MXene is planned to be distributed at Millipore Sigma.

[@jamalkhatib7610]

It great Can l get some information for type MXene that use in this application?

[@vladerikkhranovskyy5537]

Amazing! What is the loading/weight of shielding material per sqm?

[@yurygogotsi8764]

Depends on the number of dips. Very low - exact numbers are in the CARBON journal paper: www.sciencedirect.com/science/article/abs/pii/S0008622320311982

@@yurygogotsi8764 thank you! I am actually enjoing the article right now! :)

@@vladerikkhranovskyy5537 I would worry more more about air pearmability and oxidation. They may have tested in ambient conditions but they haven't thrown it into a washing machine and it would most certainly have to be air dried. If you cover it in sealed plastic might as well use copper tape.

[@a.j.drexelnanomaterialsins5931]

MXene coated fabrics is stable while multiple washing cycles ( doi.org/10.1002/adfm.201905015 ). Low concentration MXene solutions are indeed unstable in air. However, since fabrics need to be well infiltrated to exhibit shielding behaviour. Therefore dipping solution is usually of high concentration to reduce number of dip-coating cycles (approx 15 to 20 mg/mL) which increases oxidation stability.

[@aleshinteregger8554]

Hello. Can you explain me why there are no papers about MXenes at cellular frequencies? As you show it is working absorbing EM waves at these frequencies too, but I cant find any data on this. Your link refers to 8 to 13GHZ analysis.

[@Godsmessenger333]

Good question. Is there any material out there that can block ELF electromagnetic waves as this is what our cells use as frequencies.

[@Mors_Ontologica]

So does this block out infared, radio, and microwave frequencies?

[@a.j.drexelnanomaterialsins5931]

In the article doi.org/10.1016/j.carbon.2020.12.021 samples were tested within the range of 8 to 12 GHz which is Super High Radio Frequency range (SHF)

[@Godsmessenger333]

What about extremely low frequencies that’s what I’m interested in

[@donalofarrel8794]

does it may be toxic for the user? does the fabric may release toxic elements?

[@AntonioCojocariu-wy5hq]

no

[@CemSenoz]

if the phone was disconnected from the network thanks to the fabric, the call should land directly on the voicemail and not present tones... don't you agree?

[@Meditationisthebestmedicine]

how do i acquire this who sells this

[@jansmith5511]

Are these ready for wearing on the human body??? Also, this needs to be designed in the bedroom so people can sleep and not get DARPA downloads. Clothes, bedsheets, hats, gloves, even shoes. A whole assembly line of this stuff needs to be produced if this stuff is real. Also, paint and roofing materials need to be made of this stuff.

[@a.j.drexelnanomaterialsins5931]

MXene fabrics shown within the video is produced by dip-coating, however more sophisticated patterns are easily achieved by applying MXene as paint. This material is hydrophilic which allows it to be a perfect fit for conductive and shielding applications without any extra solvents and binders applied.
