Abstract
Generating aligned fibres by traditional electrospinning
setup is a significant topic which demands
serious consideration. A versatile approach for the generation
of uniaxially aligned electrospun fibre yarns by
simply altering the electrostatic properties of the polymer
solution was discussed in this work. Uniaxially aligned
electrospun poly(ethylene-co-vinyl alcohol) (EVAL) fibre
yarns were fabricated by one-step electrospinning setup.
The alignment was accomplished by increasing the solution
conductivity by the addition of AgNO3 to the solution.
The jet produced was highly stable and followed a straight
path, owing to the enhanced solution conductivity. High
degree of fibre alignment was obtained even at low surface
velocity of the collector. Subsequently the fibre yarns were
thermally reduced to obtain silver nanoparticles (Ag NPs)
on the surface of the fibres. The so produced Ag NPs
incorporated EVAL fibre yarns were characterized by
thermogravimetic analysis, energy dispersive X-ray analysis
and scanning electron microscopy. The aligned fibre
yarns also exhibited excellent mechanical strength. The
method could be recommended for the simultaneous generation
of aligned and Ag NPs impregnated fibre yarns for
broad spectrum of applications.
