Multiwall carbon nanotube-nylon-6 nanocomposites from polymerization

Multiwall carbon nanotube-nylon-6 nanocomposites from polymerization 

Owing to small production quantities in the past, research to date has concentrated on small-volume applications (electronics, sensors, etc.). However, worldwide development in synthesis of large-scale single wall carbon nanotubes (SWNT ) and multiwall carbon nanotubes (MWNTs), has encouraged research in the use of carbon nanotubes in composites. Carbon nanotube-based composites have the potential to revolutionize stmctural materials for aerospace, electrical and thermal conductors for energy applications, nano-biotechnology and other disciplines.  

Sodium hydride (NaH), 60% dispersion in oil (Fisher Scientific). Polyoxyethylene (POE), MW = 6000g/moles (Fisher Scientific). AT-acetylcaprolactam (Fisher Scientific). 

Multiwall carbon nanotubes (0.5% and 1% on weight of polymer) (Catalytic Materials, Holliston, MA). 

The mixture in the beaker was heated slowly using a Bunsen burner. The molten solution was subjected to 4 min ultrasonication (Cole Parmer Ultrasonic Processor 750 W. Parameters - 80% amplitude, 5 s on, 5 s off) to break the agglomerations of carbon nanotubes.
