Intrinsically conducting polymers have been studied extensively due to their intriguing electronic and redox properties and numerous potential applications. To improve and extend their functions, the fabrication of multifunctional conducting polymer nanocomposites has attracted a great deal of attention with the advent of nanoscale dimension. In this paper we report the comparative study of nanocomposite synthesized by an in-situ oxidative polymerization of aniline monomer in the presence of functionalized multiwall carbon nanotubes (MWCNT) with that of pure polyaniline (PANI). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and x-ray diffraction (XRD) are employed to characterize the pure PANI and the PANI-CNT nanocomposite. XRD and SEM reveal the homogeneous coating of PANI onto the CNT indicating that carbon nanotubes were well dispersed in polymer matrix. The interaction between the quinoid ring of PANI and the MWCNT causes PANI chains to be adsorbed at the surface of MWCNT, thus forming a tubular core surrounding the MWCNT was confirmed from FTIR. Nanocomposite shows high electrical conductivity compared to pure PANI. The enhancement in conductivity of the nanocomposite is due to the charge transfer effect from the quinoid rings of the PANI to the MWCNT. The effect of MWCNT on the transport properties of PANI in the form of the transport parameters such as charge localization length, most probable hopping distance and charge hopping energy in the temperature range 300-430 K was also studied.

Fiber-reinforced polymer composites find extensive applications ranging from sporting goods to aircraft components. Nonetheless, the weak interlaminar properties of laminated composites impose challenges in the design of primary load-bearing structures. The incorporation of additives (e.g., particles, films, and fibers) can overcome these limitations, offering additional functionalities to composites. Interleaving in composites generally refers to the incorporation of materials at the interface between two fiber plies so as to improve various properties. Being a simple technique to integrate in the production line, interleaving is recognized as an industrially significant and commercially viable method of modifying laminated composites. In this Review, an effort to assess state-of-the-art research on interleaving is attempted. Methods, applications, and the influence of interleaves on various properties of composites are also discussed. Data from the most recent research works on interleaved composites are compiled in an attempt to aid and encourage further developments among industries and academia.

“…Further study by Elsabee et al (2012) revealed that by lowering the surface tension of spinning solution helps the electrospinning process to be initiated even at lower electric fields [ 45 ]. It is also reported that the addition of nanomaterials such as carbon nanotubes (CNTs) has been facilitating in reducing the surface tension of the spinning solution, also aid to electrical conductivity, thus allowing the use of low high voltage applied for the spinning process [ 46 , 47 , 48 , 49 ]. Another work reported by Nayak et al (2012) has demonstrated the use of conductive additives such as sodium oleate (SO) and sodium chloride (NaCl) to aid in stabilizing the electrical conductivity during the spinning process.…”

Electrospinning technology, which was previously known as a scientific interdisciplinary research approach, is now ready to move towards a practice-based interdisciplinary approach in a variety of fields, progressively. Electrospun nanofiber-applied products are made directly from a nonwoven fabric-based membranes prepared from polymeric liquids involving the application of sufficiently high voltages during electrospinning. Today, electrospun nanofiber-based materials are of remarkable interest across multiple fields of applications, such as in electronics, sensors, functional garments, sound proofing, filters, wound dressing and scaffolds. This article presents such a review for summarizing the current progress on the manufacturing scalability of electrospun nanofibers and the commercialization of electrospun nanofiber products by dedicated companies globally. Despite the clear potential and limitless possibilities for electrospun nanofiber applications, the uptake of electrospinning by the industry is still limited due to the challenges in the manufacturing and turning of electrospun nanofibers into physical products. The recent developments in the field of electrospinning, such as the prominent nonwoven technology, personal views and the potential path forward for the growth of commercially applied products based on electrospun nanofibers, are also highlighted.
