AB  - Surface graft polymerization on multiwalled carbon nanotubes (MWCNTs) with 
      several grafting mechanisms is nowadays a demanding field of nanocomposites in 
      order to enhance the load carrying capacity, thus improving the overall 
      performance of the composites. Here, we demonstrate the covalent grafting of a 
      sulfonic acid terminated monomer, 2-acrylamido-2-methylpropane sulfonic acid onto 
      sidewalls of MWCNTs via a comparative study between oxygen plasma induced 
      grafting (OPIG), nitrogen plasma induced grafting (NPIG), and nitrogen + oxygen 
      plasma induced grafting (NOPIG) with the aim to identify the most effective 
      process for the preparation of polymer encapsulated carbon nanotubes. From the 
      detail surface analysis, it has been noticed that NOPIG offered much better 
      surface grafting than that of the OPIG and NPIG. The transmission electron 
      microscopy (TEM) images showed that MWCNTs modified by NOPIG possess much thicker 
      and uniform polymer coatings throughout. From thermogravimetric analysis (TGA), 
      the grafting degree was found to be ~80 wt % for the NOPIG sample.
