“…There are several techniques for production of nanofibers such as drawing, template synthesis, phase separation, self-assembly and electrospinning [1,4]. Amongst this techniques electrospinning is versatile for production of continuous fibers from micro scale to nanometer range [5] by the application of electrostatic forces to a jetting polymer solution [6,7]. Mechanical reinforcement of fibers by the incorporation of nanofillers has been shown as a method for enhancement of the fibers' properties for a number of particular applications.…”

We report on the synthesis and characterization of electrospun polyvinyl alcohol (PVA)/graphene nanofibers. The samples produced were characterized by Raman spectroscopy for structural and defect density analysis, scanning electron microscopy (SEM) for morphological analysis, and thermogravimetric (TGA) for thermal analysis.SEM measurements show uniform hollow PVA fibers formation and excellent graphene dispersion within the fibers, while TGA measurements show the improved thermal stability of PVA in the presence of graphene. The synthesized polymer reinforced nanofibers have potential to serve in many different applications such as thermal management, supercapacitor electrodes and biomedical materials for drug delivery.

“…The calibration of the lateral force of AFM cantilevers is still a matter of debate despite lateral force measurements being produced with the AFM for almost 25 years. 51,52 Previously described methods for manipulation of individual fibres and fixing them at two points are both time consuming, [53][54][55][56] and prone to add defects to the fibres.…”

Tensile testing of individual glassy, rubbery and hydrogel electrospun polymer nanofibres to high strain using the atomic force microscope

The production and use of polymer nanofibre assemblies prepared by electrospinning is now widespread. It is known that the tensile properties of electrospun polymer fibres can be different to those of bulk polymers. Here, we report a general method for measuring the tensile properties of individual electrospun nanofibres that employs a commercial atomic force microscope. Methods for preparing samples, force calibration and calculation of tensile stress and strain are described along with error estimation. By appropriate choice of AFM cantilever, it is shown that the tensile stress-strain curves can be measured for glassy, rubbery and gel polymer nanofibres. Testing can be in air or fluid and to strains of 300%. Example results illustrate the usefulness of the technique with the observation of high ductility in normally brittle glassy polymers such as polystyrene, and unusually large hysteresis in thermoplastic elastomer nanofibres. These observations provide new insights into the structure and mechanical behaviour of nanoscale polymeric materials. 2013 Elsevier Ltd. All rights reserved.

“…One single-rolled graphite sheet is called a single-walled carbon nanotube (SWCNT), while several SWCNTs nested together in a concentric fashion comprise a multi-walled carbon nanotube (MWCNT) (Pan and Xing, 2008). They consist of sp 2 carbon atom arrangements in a fused benzene ring configuration, which results in exceptional physicochemical properties and consequentially their incorporation into a vast array of composite materials (Liu et al, 1999;Snow et al, 2005;Mauter and Elimelech, 2008;Almecija et al, 2009). An excellent and more detailed discussion about the unique physicochemical properties of CNTs is provided by Mauter and Elimelech (2008).…”

Abstract. The exceptional sorptive ability of carbon nanomaterials (CNMs) for hydrophobic organic contaminants (HOCs) is driven by their characteristically large reactive surface areas and highly hydrophobic nature. Given these properties, it is possible for CNMs to impact on the persistence, mobility and bioavailability of contaminants within soils, either favourably through sorption and sequestration, hence reducing their bioavailability, or unfavourably through increasing contaminant dispersal. This review considers the complex and dynamic nature of both soil and CNM physicochemical properties to determine their fate and behaviour, together with their interaction with contaminants and the soil microflora. It is argued that assessment of CNMs within soil should be conducted on a case-by-case basis and further work to assess the long-term stability and toxicity of sorbed contaminants, as well as the toxicity of CNMs themselves, is required before their sorptive abilities can be applied to remedy environmental issues.
