Hi is there any way to functionalize CNT without in situ reduction of the metal nanoparticles on the CNT. Maybe by increasing affinity of CNT for the metal nanoparticle and mixing them mechanically?
Dear friend Alex Paul
When we want to make carbon nanotubes (CNTs) even cooler by adding tiny metal particles to them, we have different methods we can use. One way that scientists often use is called "in situ reduction." It's when they reduce the metal particles right on the surface of the nanotubes.
But guess what? There are other really interesting methods we can explore too!
One cool approach involves changing the surface of the nanotubes to make them work better with the metal particles. We do this by adding special things called functional groups or coatings to the nanotubes. These additions make the nanotubes and metal particles get along really well. It's like they become best friends! When they like each other more, the metal particles can spread out evenly on the nanotubes and stick to them better when we mix them together.

Lets keep in touch and explore this question at your convenience.
Hi Kaushik Shandilya , I was wondering would CNT create an electrical network within a polymer composite when micron size silver particles are dispersed within the polymer? Most papers I read have some advanced method of in situ reduction with some people opting for sputtering/thermal evaporation for CNT decoration. This got me thinking maybe CNT's will not interact with metallic powders simply dispersed in the matrix is this conclusion right?
Dear friend Alex Paul
Thanks for asking questions.
Based on my understanding, dispersing micron-sized silver particles within a polymer matrix may not directly create an electrical network with carbon nanotubes (CNTs) in the composite. The interaction between CNTs and metallic powders depends on several factors, including their dispersion, compatibility, and connectivity within the matrix.
While some advanced methods like in situ reduction, sputtering, or thermal evaporation are commonly used to enhance the interaction between CNTs and metal particles, simply dispersing metallic powders within the polymer matrix may not provide sufficient connectivity or contact with the CNTs.
CNTs possess excellent electrical conductivity and can act as conductive pathways within a composite material. However, for effective electrical network formation, it is crucial to establish a strong interface and contact between the CNTs and metal particles.
In the case of dispersing micron-sized silver particles within the polymer matrix, the direct interaction between CNTs and metal particles might be limited due to their size difference and distribution. Achieving a well-dispersed and interconnected network of CNTs and metal particles typically requires additional techniques such as in situ reduction or specific surface modification approaches.
Therefore, it is possible that simply dispersing metallic powders within the polymer matrix may not lead to the desired electrical network formation with CNTs. To create a more effective electrical network, additional methods or modifications may be necessary to ensure better connectivity and interaction between CNTs and metal particles.
It is important to note that specific experimental conditions and the characteristics of the materials used may influence the outcomes. Further research and experimentation would be needed to explore the interactions between CNTs and metallic powders in polymer composites and to determine the most suitable methods for achieving an electrical network within such systems.
