Anshuman Das Yes, Multi-Walled Carbon Nanotube (MWCNT) nanopowders are often regarded as superior to other nanoparticles for formulating nanofluids, particularly in machining activities. Their unique properties enhance thermal conductivity, lubrication, and overall machining performance.

[1] study show that MWCNT-based nanofluids can achieve up to 105% improvement in heat transfer compared to conventional fluids. This study also reported a 15% reduction in cutting force and a 25% decrease in temperature when using MWCNT composites in turning operations [1].

MWCNTs are often preferred due to their exceptional thermal conductivity, mechanical strength, and large aspect ratio, which enhance heat transfer properties. Compared to other nanoparticles, MWCNTs offer better stability in suspension and lower viscosity at high concentrations, improving the performance of nanofluids in heat transfer applications. Their unique structure allows for efficient electron transport, make it more effective in many applications.

It depends on the application. Due to MWCNT unique structure it has unique properties. You can refer my latest publication for more informations.Article Comparative Study on the Thermal Properties of Engine Oils a...
