Carbon nano tubes display an array of electrical properties ranging from highly metallic to highly semi conducting depending on the diameter and chirality of the tubes.
In practice it would be advantageous to be able to access an even wider array of CNT properties for varied applications. One way to do this is to utilize metal infiltrated carbon nano tubes. Metal infiltration provides a method to increase the range of CNT properties independent of chirality.
Filling CNTs with desired metals can alter CNT capacitance as well as electrical resistance properties. Thereby optimizing their suitability for various applications. The utility of this process has just begun to be explored.
NSN’s process can also be used to both fill and coat CNTs with metal nano particles. One lucrative possible application of these filled and coated materials is as catalysts. In tests both Platinum and Rhodium filled single walled carbon nano tubes have proven to be more effective catalyst than the respective metal nano particles alone.
NSN has experience in infiltrating single, double and multi-wall CNTs with various metals, including Titanium, Iron, Platinum, Palladium and Silver. In principle nearly any desired metal can be infiltrated into CNTs by this process.
