SEM and TEM images with contact angle images of MWCNTs and NH2/MWCNTs. SEM images of (a) pristine MWCNTs, (b) NH2/MWCNTs with 5 × 1014 ions/cm2, (c) NH2/MWCNTs with 1 × 1016 ions/cm2. TEM images of (d) pristine MWCNTs, (e) NH2/MWCNTs with 5 × 1014 ions/cm2, (f) NH2/MWCNTs with 1 × 1016 ions/cm2. The insets are their contact angle images, respectively.
