Table 1: TGA Data.

TGA comparison between all CNTs and dMWCNTs shows % functionalization, residuals and temperature of maximum decomposition. CNTs originally contained high amounts of residual metal catalyst that are removed during the process to make dMWCNTs. The process to make dMWCNTs also increases the oxidative functionalization from 0.3334% (w/w) to 2.228% (w/w). Successful functionalization of dMWCNTs with PEG is indicated by the increase in % functionalization (determined by weight loss between 200 and 600°C) originating from the ether bonds of PEG. Successful attachment of the BT agent is indicated by the shift in temperature of maximum decomposition from 332.22 to 377.64, most likely originating from the presence of phosphate groups found on the BT agent.
