Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. A process by which the ability to manipulate individual atoms and molecules might be developed, using one set of precise tools to build and operate another proportionally smaller set, and so on down to the needed scale. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. Nanofibres are nanomaterials having two dimensions in nanometer range that include nanorods and nanotubes and possess flexibility. Nanofibres are produced by drawing, template synthesis, phase separation, self-assembly and electrospinning. Electrospinning is one of the most preferred processes due to its varied advantages including cost effectiveness, zero discharge, adaptability and scalability.
Electrospinning produces nanofibres from conducting polymers. A conducting polymer solution or melts are subjected to very high voltage to draw very fine fibres which get collected on the counter electrode. The parameters like polymer concentration, solvent system, voltage, rate of solution discharge and the distance between electrodes decide the quality of the final product. The produced electrospun nanofibre have a very high surface area to volume ratio and porous structure make them suitable for a wide variety of applications like filtration, technical textiles, medical textiles, scaffolds, drug delivery system, effective release of pheromones for pest control, seed treatment using minimal chemicals, carriers for bio-fertilizers, nanosensors for packaging of perishable commodities & various pollutants, and so on.
