Abstract

Carbon nanotubes were synthesized by using chemical vapor deposition using polyethylene terephthalate (PET) waste. The CNTs that were produced were functionalized with organic acid namely benzoic acids from 0 up to 70 kGy using gamma irradiation. To determine the acid groups, acid base titration was utilized whereas transmission electron microscope was used to determine the morphology of the functionalized CNT and dispersion characteristic was carried out for pristine and functionalized CNTs. The results obtained show that gamma irradiation significantly induce acid functionalized CNT as compared to unirradiated acid functionalized CNT. This indicates the importance of radiation technique in functionalizing carbon nanomaterials which is feasible, green, clean and process-effective.
