Investigation of shear-induced rearrangement of carbon nanotube bundles using Taylor–Couette flow

Abstract

The rearrangement of CNT bundles depends on the flow pattern and flow-induced shear stress. When the Taylor–Couette flow is stable and laminar, and has sufficiently low shear stress, CNT assemblies assume a highly aligned and densified structure.

Structural engineering of single-crystal-like perovskite nanocrystals for ultrasensitive photodetector applications

“…Under weak agitation and weak shear flow, the primary nanowires aggregated via side-toside packing into superstructures that resulted in the formation of highly crystalline nanorod particles, which can be explained by the Ostwald ripening mechanism. [33][34][35] X-Ray photoelectron spectroscopy confirmed that CsPbBr 3 QDs, NWs, and NRs had identical binding energies in the desired chemical compositions (Fig. S1, ESI †).…”

Analysis of Dispersion of Carbon Nanotubes in m-Cresol

“…To produce highly aligned CNT assemblies, a solution processing technique that includes shear aligning is desirable. In this processing, first, the as-supplied CNTs are disentangled, which are typically entangled at various hierarchical levels, and proper shear stresses are applied so that the CNTs are aligned [ 15 ]. For such a shear-aligning solution processing, the ability of a solvent to disperse CNTs individually is required.…”
