Respected, Researcher,
Kindly suggest the important 2D materials which show the highest EMI property.
I am looking forward to the design and fabrication of a radio frequency (RF) Antenna.
As I found, the Ti3CTx shows 98dB EMI shielding.
What are the other materials that indicate more than this? If so, kindly mention it in the comments.
Herewith I attached one related paper for the same.
Thank you for your support and suggestions.
You can use frequency selective surface (FSS) as an EMI shielding application. By studying the shielding effectiveness.
For EMI shielding, it is important to not just look at the absolute value, but to also consider the thickness of the material. For EMI shielding materials, the higher the conductivity, the better the EMI shielding ends up being (in most cases!) Generally, what we've observed for MXenes (Mn+1XnTx) are that their EMI shielding efficiency also depends on the conductivity of the MXene. To date, the highest conductivity reported for a MXene is Ti3C2Tx which has values above 20,000 S/cm: Article Modified MAX Phase Synthesis for Environmentally Stable and ...
Considering this, Ti3C2Tx appears to be the best MXene for EMI shielding. However, there was a recent article published in Science:Article Anomalous absorption of electromagnetic waves by 2D transiti...
that shows that annealed Ti3CNTx has a higher EMI shielding value at the same thickness. This means that there is some fundamentally different mechanism that is occurring with Ti3CNTx over Ti3C2Tx.Now, to further add some information, all MXenes will have EMI shielding capabilities, but at different amounts. In this article, 15+ MXenes were tested using a uniform methodology:Article Beyond Ti3C2Tx: MXenes for Electromagnetic Interference Shielding
. What we found is that generally MXenes will follow the correlation between conductivity and EMI shielding efficacy. However, some MXenes show significantly higher EMI shielding efficiency than is expected based on their conductivity, meaning that there is some other physics happening that we currently cannot explain.- Badges
