Preparation Of Poly(Acrylic Acid) Grafted Multiwalled Carbon Nanotubes By A Two-Step Irradiation Technique

A facile strategy to prepare water-soluble multiwalled carbon nanotubes (MWNTs) by two steps of gamma radiation is developed. First, MWNTs are irradiated in ethanol. The radiolysis of ethanol produces many active species such as (CHCH2OH)-C-center dot and (CH)-C-center dot(CH3)OH which react with C=C bonds on the surface of MWNTs. Afterwa...更多
