“…Even more complicated is the situation if one tries to use the nanofibers as reinforcement for polymer nanocomposites -the dispersion problem is becoming practically non-soluble not only because of the difficulties stemming from the nano-sizes but also due to the network character of the mat. Using various techniques, the local molecular orientation of the polymer chains within the fibers has been measured and found that the degree of orientation of the polymer chains with respect to the fiber axis increases with decreasing fiber diameters [165][166][167][168][169].…”

“…The perfect molecular orientation during the cold drawing is shown on the wide-angle X-ray scattering (WAXS) patterns displayed in Figure 6 taken from extruded PP/PET bled before and after cold drawing. This perfect molecular orientation represents one of the basic differences between the electrospun fibers and those prepared using the concept of microfibrillar composites [183] -the formation of electrospun fibers takes place in polymer solutions or melts where the drawing could hardly result in significant molecular orientation as demonstrated above [165][166][167][168][169][170].…”

Polymer nanocomposites: Why their mechanical performance does not justify the expectation and a possible solution to the problem?

The expected order-of-magnitude enhancement in modulus (at loadings less than 1%) of polymer nanocomposites has proven elusive-the observed improvements are 10-35% only. The failure of the concept has been attributed to poor dispersion, poor interfacial load transfer, process-related deficiencies, and others. Due to the inherent property of the nano-size materials, their extremely high specific surface, they tend to agglomerate, and their further dispersion in the matrix component is practically impossible. For this reason, the composites prepared via blending a polymer with a nano-size material are microcomposites instead of nanocomposites, as demonstrated by light scattering studies. So long as reliable tools and/or techniques for proper dispersion of nanomaterials are missing, we must use methods free of the dispersion step in the manufacturing process. The relatively new 'concept of converting instead of adding' offers two such techniques-instead to take the matrix and the reinforcement in their final form and blend them, one takes one component only and during the processing creates the missing second component. Both approaches result in true nanocomposites with superior mechanical performance-the improvements of the tensile strength for nanofibrillar polymer-polymer and single polymer composites are up to 200 and 440%, respectively, (or even up to 650% if trans-reaction catalyst is used).

“…A polymer solution or melt can be electrospun if it is able to carry an electric charge and has enough viscosity to be strained without breaking up into droplets. Up to now, more than 200 types of materials have been electrospun into nanofibres, among which natural and synthetic polymers and many hybrid blends [6].…”

Nanotechnology exerts a significant influence on materials science, providing new insights into the design of functional materials. One of the most studied areas of nanotechnologies is that of nanofibres, characterised by high specific volume, chemical activity and volume-dependent physical processes. The most promising method of producing nanofibres with various morphologies and functionalities from different materials is electrospinning, where high voltage is applied between the spinneret and the collector to the charged polymer solution (or melt) to draw polymer filaments. This chapter reviews the main electrospinning techniques for producing nanofibres from polymers, provides an overview on the influence of the spinning solution characteristics, the process parameters and the working environment on the process and highlights the many applications of electrospun nanofibres in the field of sensors. Latest advances in this field and the prospects for obtaining new electrospun nanofibre sensors are discussed.

The paper describes the process of obtaining electrospun nanofibers from solutions of polyvinyl chloride in tetrahydrofuran and in a mixture of tetrahydrofuran and dimethylformamide. The regularity of size variation of polyvinyl chloride nanofibers depending on the selected technological parameters was analyzed. The optimal formulation for the preparation of the polymer solution was chosen on the basis of the obtained experimental data. That developed formulation ensures the stability of the electrospinning of nanofibers with desired morphological characteristics. The results of the experiment show that increasing of polyvinyl chloride concentration from 10 to 30 mass. % leads to increasing in the diameter of electrospinning nanofibers based on polyvinyl chloride from 291 nm to 395 nm. The tensile strength and tensile modulus for electrospun nanofiber films based on polyvinyl chloride are 2.21 MPa and 53.2 MPa, respectively.
