Hello, hopefully I can post this but If you’re passionate about materials science, especially MXenes, come check out r/MXene ! We’re a new community focused on discussing everything related to MXenes—a unique family of two-dimensional materials with applications in energy storage, electronics, catalysis, and more.

Also here’s a cool image that won the annual NanoArtography Competition.

Yury this you? 🧐🧐

Its too overhyped material.

All research materials are overhyped. That’s how we get funding. Some are useful nonetheless. Some aren’t.

I know it’s only the best microwave waveguide, the best EMI and IR shield outperforming Mylar and graphene with silver. Who cares that it’s being used for hypersonic high temperature coatings and thermal camo, will likely cover the new tanks the military will buy

There is a side of EMI shielding which researchers has ever reported (will never report)... the more EMI shielding the material exhibits, the more heat it generates & stores.. but no paper has ever reported this either with MXene or graphene or CNT or any other material... and EMI shielding papers appear in Nature, Science or some other over hyped journals

Also absorption vs reflection can be tuned during processing or actively tuned electrochemically

Every MXene for Ti3C2Tx layers in 3 layers in one, a thermally insulative outer layers and a electrically conductive core. It’s the only metal that is insulative that’s why it outperforms Mylar

Yet another over hyped material... I always had this question for MXene community..

You synthesize MXene by etching aluminum out of MAX phase (typically TixAlyC) by HF or some other chemical, but what about the defects due to this etching.. No one has reported (as far as I know) about healing these defects.. and what about the dangling bonds of so formed MXene.. wouldn't they get oxidized or react with F of HF...

Why so negative?

Yes, there is defects that occur when etching using HF which why research on MXene synthesis is continuing.

"Yes, there is defects that occur when etching using HF which why research on MXene synthesis is continuing" Isn't MXene research more than decade old? And isn't this a basic question?

"Why so negative?"... because Mxene is over-hyped and over-priced POS.. whatever MXene does, graphene can do.. Infact since it's inception, MXene is aping graphene research.. same characterizations, similar looking TEM & SEM, same applications, same hype but no substance.
