“…The formation of an electrospun fibrous structure depends on the construction and geometrical shape of the electrospinning machine set‐up. Number of crossings per nanofiber, number of intersections per unit area, total nanofiber crossings in the mat and three dimensional joints morphology play an important role in the mechanical properties of the nonwoven nanofibers mat 43. However, the nanofiber molecular structure and orientation play even more important critical role in these properties 8.…”

In this article, we have aimed to mechanically characterize the nylon 6 single nanofiber and nanofiber mats. We have started by providing a critical review of the developed mechanical characterization testing methods of single nanofiber. It has been found that the tensile test method provides information about the mechanical properties of the nanofiber such as tensile strength, elastic modulus and strain at break. We have carried out a tensile test for nanofiber/composite MWCNTs nanofiber mats to further characterize the effect of the MWCNTs filling fiber architecture. In addition, we have designed and implemented a novel simple laboratory set‐up for performing tensile test of single nanofibers. As a result, we have established the stress–strain curve for single nylon 6 nanofibers allowing us to define the tensile strength, axial tensile modulus and ultimate strain of this nanofiber. The compared values of the tensile strength, axial modulus and ultimate strain for nylon 6 nanofiber with those of conventional nylon 6 microfiber have indicated that some of the nylon 6 nanofiber molecule chains have not been oriented well along the nanofiber axis during electrospinning and through the alignment mechanism. Finally, we have explained how we can improve the mechanical properties of nylon 6 nanofibers and discussed how to overcome the tensile testing challenges of single nanofibers. © 2010 Wiley Periodicals, Inc.

“…24 The CNT were considered to be isotropic with E f 5 545 GPa and v f 5 0.3. 25 The effective axial modulus in dimensionless form hE zz i/E m , and the transverse modulus hE xx i/E m on micro level, for the range of volume CNTs fractions are shown in Figure 12. The hE xx i is greatly influenced by the presence of CNTs, while hE yy i is insensitive to CNTs, due to the matrix presence three orders smaller modulus.…”

The carbon nanotube (CNT) structure is a promising building block for future nanocomposite structures. Mechanical properties of the electrospun butadiene elastomer reinforced with CNT are analyzed by multiscale method. Nanofiber diameter dependence on electric field and solution concentration is estimated from experimental data. The fiber microscale effective properties are determined by homogenization procedure using modified shear-lag model, while the point-bonded stochastic fibrous network on the mesoscale replaced by continuum effective sheet. Random fibrous network was generated according experimentally determined stochastic quantifiers. The influence of CNT reinforcement on elastic modulus of electrospun sheet on macroscopic level is determined by finite element method.

The use of clay mineral in modifying the properties of polymeric material is improved in application. The current interest in modifying the polymeric materials, particularly polyethylene, polypropylene, polystyrene, and nylon using clay mineral for improved flame retardancy, thermal stability, peak heat release rate, fracture, and strength properties generated significant research literature. This paper aims to review some of the important recent modification achieved in the performance of polymeric materials using organoclay mineral. Degradation of clay mineral-polymer (nm) composite is discussed with appropriate known examples. Clay mineral (nm) loading of 5 wt.% to 7 wt.% that was significantly smaller than the percent loading of conventional fillers in polymeric materials introduced significant improvement in terms of thermal and physical stability. An attempt is made to emphasize flammability and thermal stability and to indicate the areas that are relatively little explored in modification of fiber-forming polymers to enhance further research interest.
