Fabrications of Bifunctional Janus and Triblock Saturn Colloids

Lin C.C., Ho C.-C., Chang C-C, Kuo C., National Cheng Kung University, TW

A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer [...]

Control of Nanoparticle on Nanofiber via Magnetic Electrospinning

Chung M., Lan J.W., Lin H-Y, Suen T.W., Cheng S.H., Southern Taiwan University, TW

Nanoparticles added into nanofibers produced by electrospinning can expand the functions of such fibers, and these nanoparticles can serve as vehicle for drugs in active drug delivery concept. Depending on the toxicity of these nanoparticles, [...]

Impedance of Nanoparticles Embedded Electrospun Nanofiber

Chung M., Lan J.W., Lin H-Y, Suen T.W., Cheng S.H., Southern Taiwan University, TW

Electrospinning produces nanofibers with diameters ranging from 100-500 nm under 10-20 KV at 10-20 cm distances, and if these nanofibers were composed of polymers like PVA or PVP, they are usually nonconductive with resistances too [...]

Preparation and characterization of electrospun nickel oxide/polymer fibrous electrodes for electrochemical capacitor

Tsutsumi H., Hosogai S., Yamaguchi University, JP

Electrospinning provides a simple and unique technique for preparation of fibers with the diameters ranging from the nano- to microscale. We prepared the electrospun fiber which contains nickel oxide (NiO) as the electrochemical active material [...]

Electrospun TiO2 Fibers as a Material for Dye Sensitizied Solar Cells

Duchoslav J., Rubáek L., Kavan L., Zukalová M., Procházka J., Elmarco Ltd., CZ

Electrospinning is a method for producing polymeric fabric with fibers ranging from 50 to 500 nm in diameter. It has been demonstrated that fibrous structure is preserved even after annealing when precursor of inorganic compound [...]

Preparation and characterization of highly porous PVDF nanofibers and yarns

Andrukh T., Few C., Burtovyy O., Burtovyy R., Burtovyy O., Burtovyy R., Luzinov I., Kornev K., Clemson University, US

Unique highly porous Polyvinylidene difluoride (PVDF) nanofibers (Figure 1) of about 50-500 nm in diameter were prepared by electrospinning. Electrospinning setup (Figure 2) allows us to control the nanofiber placement on the gap-type electrodes. In [...]

The anti-ultraviolet nano-fibers formed during electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In this study, electrospinning is a straightforward method to produce anti-ultraviolet polymer fibers. The new types of anti-ultraviolet nano-fibers were produced by polylactic acid (PLA) and benzophenone. We also used different anti-ultraviolet nano particles (TiO2, [...]

The First-aid strip of copolymer, produced by electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In the study of biomimetic material design, mimicking nanostructured thin film components can take the place of the extracellular matrix. The new types of thin film were fabricated by polylactic acid (PLA) and hyaluronic acid [...]

Characterization of new type polymer composites prepared by in situ coffining electrospun fibers into polymer matrixes

Tsutsumi H., Hara C., Yamaguchi University, JP

A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. Many difficulties (for example, increasing viscosity of processing fluid, homogeneity of fibers in the [...]

Electrospun Nanofibrous Membrane Biosensor for lactate

Romero J., Moreno I., González V., Centro deInvestigación en Química Aplicada, MX

Electrospinning is a simple, non mechanical method used to produce non-woven fabrics of ultrafine fibers in the nanometer diameter range (nanofibers).This method is appropriated to obtain high-surface-area polymeric fibrous membranes and is a one-step process [...]
