摘要
The temperature-responsive multi-walled carbon nanotubes (MWCNTs) were prepared by decorating MWCNTs with poly(N-isopropylacrylamide) (PNIPAM) chains via surface-initiated redox polymerization. Chemical structure of resulting product and the quantities of grafted polymer were determined by FT-IR and TGA. TEM and FE-SEM images clearly indicate that the nanotubes were coated with a PNIPAM layer. DSC analysis indicates that the functionalized MWCNTs can respond to temperature, because of the hydrophilic and hydrophobic transformation of the bonded PNIPAM chains at 30-35 degrees C.
