A cost-effective and potentially industrially scalable, in situ functionalization procedure for preparation of soluble graphene nanoribbon (GNRs) from commercially available carbon nanotubes is presented. The physical characteristics of the functionalized product were determined using SEM, evolved gas analysis, X-ray diffraction

A facile and cost-effective approach to the fabrication of a nanocomposite material of polyaniline (PANI) and graphene nanoribbons (GNRs) has been developed. The morphology of the composite was characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron microscopy, and

A thermoplastic polyurethane (TPU) composite film containing hexadecyl-functionalized low-defect graphene nanoribbons (HD-GNRs) was produced by solution casting. The HD-GNRs were well distributed within the polyurethane matrix, leading to phase separation of the TPU. Nitrogen gas effective diffusivity of TPU was

Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.

Since its discovery little more than a decade ago,1 the two-dimensional (2D) allotrope of carbon—graphene—has been the subject of intense multidisciplinary research efforts.

Graphene's unique properties spark interdisciplinary interest; its honeycomb structure offers electrical, optical, and mechanical marvels.

Graphene nanoribbons (GNRs) are quasi-one-dimensional narrow strips of graphene comprised of sp2-hybridized carbon atoms arranged into hexagonal honeycomb lattice configurations.
