CNT/Polymer Nanocomposites: A Detailed Review on Mathematical Modeling 189
Merck, 98%), and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA, Aldrich,
99%) were all used without any further purification. The SWCNTs (HiPCO, CNI)
were used as purchased and contained 5% w/w iron residue as determined by elemen-
tal analysis. The AMPSA (0.4 g) was sonicated for a few seconds in 20 g DCAA to
produce a colorless solution. SWCNTs (18 mg) were then added to this solution, and
it was sonicated for 30 min. Separately, the 0.9 g of AMPSA was added to 1.0 g of
PAni eEmeraldine base) powder, and ground using a mortar and pestle to obtain a grey
powder. The resultant powder was added to the prepared solution containing SWCNTs
and AMPSA in DCAA. The solution ...
