A new route consisting of simultaneous centrifugal spinning and solution blowing to form polymer nanofibers is reported. The fiber diameter (60–1000 nm) is shown to be a function of polymer concentration, rotational speed, and working pressure of the processing system. The fiber length is dependent on the rotational speed. The process can deliver 6 kg of fiber per hour and therefore offers mass production capabilities compared with other established polymer nanofiber generation methods such as electrospinning, centrifugal spinning, and blowing.

“…When the solution is spun into fibers in the presence of a magnetic field generated by two parallel-positioned permanent magnets, the magnetic field stretches the fibers across the gap to form a parallel array as they land on the magnets. In the same year, Ajao et al 148 demonstrated fiber alignment on one face of a box made from Si wafers with a cylindrical magnet inside. Here well-aligned nanofibers were only observed on a particular side (top) of the magnet within the electric-magnetic field while the other sides presented diverse microstructures.…”

Recent advances in large-scale assembly of semiconducting inorganic nanowires and nanofibers for electronics, sensors and photovoltaics

Semiconducting inorganic nanowires (NWs), nanotubes and nanofibers have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics, chemical/biological/ optical sensing, and energy harvesting, storage and conversion, etc. Besides the top-down approaches such as conventional lithography technologies, nanowires are commonly grown by the bottom-up approaches such as solution growth, template-guided synthesis, and vapor-liquid-solid process at a relatively low cost. Superior performance has been demonstrated using nanowires devices. However, most of the nanowire devices are limited to the demonstration of single devices, an initial step toward nanoelectronic circuits, not adequate for production on a large scale at low cost. Controlled and uniform assembly of nanowires with high scalability is still one of the major bottleneck challenges towards the materials and device integration for electronics. In this review, we aim to present recent progress toward nanowire device assembly technologies, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic-field-directed assembly, contact/roll printing, planar growth, bridging method, and electrospinning, etc. And their applications in high-performance, flexible electronics, sensors, photovoltaics, bioelectronic interfaces and nano-resonators are also presented.

“…A distinct advantage of this technique compared to electrospinning is a significant reduction in the random orientation of fibres formed. This is largely due to nonexistence of whipping or non-axisymmetric instabilities and in the absence of an electric field the nonexistence of repulsive forces brought about by surface charges can help to form well-ordered nanofibres (Ajao et al, 2010).…”
