Synthesis and optoelectrical properties of chemically unzipped carbon nanotubes by modified Hummers’ technique: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0








On this work, multi-walled carbon nanotubes (MWCNTs) have been unzipped using the modified Hummers method as an effectual process to ship extremely unzipped graphene nanoribbons (GNRs) employed for the fabrication of a lightweight sensor. The chemical unzipping was additionally attained by modifying the oxidation time to make sure an excellent unzipping effectivity and a better fee of exfoliation of the MWCNTs. The affect of soaking time on the unzipping effectivity of the MWCNTs has been examined. Moreover, SEM, TEM, FTIR, X-ray diffraction (XRD) and Raman examinations have been utilized to watch and characterize the method of unzipping of MWCNTs. Schottky diode primarily based on the unzipping MWCNTs was fabricated. The optoelectrical properties of the chemically unzipped carbon nanotube (CNT) by the modified hummers technique have been studied. The excessive unzipping effectivity was an excellent method used for the fabrication of a promising Schottky diode photosensor which was revealed by the I–V traits curves. A 532 nm laser was used to calculate the quantum effectivity. Based mostly on the obtained outcomes, the synthesized GNRs have very promising purposes in lots of fields together with micro and nano optoelectronics.
