FESEM images of HNTs (A) before and (B) after surface modification with an aminosilane. (C) FTIR spectra demonstrate the chemical change due to the grafting of aminosilane on the surface of HNTs. (D) TEM image of aminosilane modified single HNT, representing HNTs consist of cylindrical shaped tubes with an open-ended lumen.
