High shear thin film fabrication of nanocarbon

hin film microfluidics is developing for a wide range of applications, and includes the synthesis of various types of nanocarbon
material, involving both ‘top down’ and ‘bottom up’ continuous flow processing. Such processing addresses scalability at the
inception of the science, and is applicable not just to the synthesis of nanocarbon, but also composites or hybrid material where one
or more components is nanocarbon. We recently developed the vortex fluidic device (VFD) as a thin filmmicrofluidic platformwhere
the liquid is subjected to shear stress (mechanical energy) in a rapidly rotating tube. The shear stress offers scope for controlling the
shape, morphology and size of carbon nanomaterial, with the prospect of high green chemistry metrics of the processing. Applications
of the VFD are many and varied, and for nanocarbon we have established (i) the formation of toroidal arrays of SWCNTs with control
over their diameter, (ii) the slicing of SWCNTs, DWCNTs and MWCNTs while the thin film is irradiated with a 1064 nm wavelength
pulsed laser, in the absence of harsh chemicals, exfoliation of graphite, and (iii) assembling fullerene C60 into nanotubules in the
absence of surfactants. Other aspects of composite structures of nanocarbon generated in the VFD for both confined mode and
continuous flow mode will be presented.
