Fabrication of Nanoporous Fibers via Bubble Electrospinning
Recently, nanoporous fibers have been caught much attention as the most promising material in nanotechnology. To our knowledge, nanoporous materials have extremely high surface area and are widely used in different fields, such as filtration, radiation protection, catalysis, sensors, tissue engineering, and drug delivery [1-2]. Electrospinning is an effective method, which can fabricate polymer...
متن کاملFabrication of CH3NH3PbI3/PVP Composite Fibers via Electrospinning and Deposition
In our study, one-dimensional PbI₂/polyvinylpyrrolidone (PVP) composition fibers have been prepared by using PbI₂ and PVP as precursors dissolved in N,N-dimethylformamide via a electrospinning process. Dipping the fibers into CH₃NH₃I solution changed its color, indicating the formation of CH₃NH₃PbI₃, to obtain CH₃NH₃PbI₃/PVP composite fibers. The structure, morphology and composition of the all...
متن کاملThe fabrication of polymeric nanochannels by electrospinning.
Polymeric nanochannels have been fabricated using a cost-effective, fast, one-step method involving the collision of nanosized jets during electrospinning. The nanochannels had a uniform U-shaped cross-section, with a height below 100 nm and lengths around 1 mm. It was explained that the strength of the electric field had an important effect on the formation of the nanochannels. An adhesion tes...
متن کاملElectrospinning: A whipping fluid jet generates submicron polymer fibers
Polymeric fibers with diameters in the range from 50 nm to 5 mm are produced by accelerating a fluid jet in an electric field, in a process known as ‘‘electrospinning.’’ Here we show that an essential element of the process is a fluid instability, the rapidly whipping jet. The phenomena responsible for the onset of whipping are revealed by a linear instability analysis that describes the jet be...
متن کاملSuperhydrophobic and oleophobic fibers by coaxial electrospinning.
Control of surface wetting properties to produce strongly hydrophobic or hydrophilic effects is at the heart of many macro- and microfluidic applications. In this work, we have investigated coaxial electrospinning to produce core-sheath-structured nano/microfibers that combine different properties from individual core and sheath materials. Teflon AF is an amorphous fluoropolymer that is widely ...
