“…Attempts to improve the outstanding electrical, thermal and mechanical properties of MWCNTs by improving their dispersion in NR-latex are important in the development of better components for use in nanowires in aerospace applications [11,12]. In this study, a stable, colloidal mixture of MWCNTs in a polymer matrix was obtained through latex technology via surfactant utilisation [15].…”

“…They possess outstanding electrical, mechanical and thermal properties compared to conventional fillers, such as carbon black [5,6], and have therefore already attracted interest in various industries for possible applications in electronics [7] and medicine [8] and as flame retardants in polyurethane and polypropylene [9,10]. More recently, they have also been used in aerospace-based technology [11,12]. Conductive materials such as copper are conventionally employed to fabricate wire components.…”

Preparation of multiwall carbon nanotubes (MWCNTs) stabilised by highly branched hydrocarbon surfactants and dispersed in natural rubber latex nanocomposites

The performance of single-, double-and triple-chain anionic sulphosuccinate surfactants for dispersing multiwall carbon nanotubes (MWNCTs) in natural rubber latex (NR-latex) was studied using a range of techniques, including field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and Raman spectroscopy. The conductivities of the nanocomposites were also investigated using four-point probe measurements. Here, MWCNTs were efficiently dispersed in NR-latex with the aid of hyperbranched tri-chain sulphosuccinate anionic surfactants, specifically sodium 1,4-bis(neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulphonate (TC14). This paper highlights that TC14 performs much better than that of the commercially available surfactant sodium dodecyl sulphate (SDS), demonstrating how careful consideration of surfactant architecture leads to improved dispersibility of MWCNTs in NR-latex. The results should be of significant interest for improving nanowiring applications suitable for aerospace-based technology.

“…It is thus a promising approach to alleviating some of the limitations. Athreya et al [63,64] performed laser sintering of nanosized carbon black powder blended with nylon-12 powder. It has been observed that nylon -12 composites possessed flexural modulus lower than that of pure nylon-12 composites depending upon the laser power and scan speed.…”

Abstract-Additive Manufacturing (AM) process has been effective in producing materials that are being utilized by the aerospace industry in order to improve their performance by increasing their properties. Industry now opts for this technique over conventional methods as it has enormous advantages and applications. This Additive Manufacturing process is capable of producing complex near net shape of parts. The materials that are produced by this technique for aerospace industries are metal alloys, metal matrix composites, polymer matrix composites, ceramic matrix composites and nano-composites. Many of the composite materials are still under research and development. In this study, a literature review on the mechanical properties of the materials that are used in the aerospace industry by AM process is discussed and these properties are also compared with the materials produced by conventional methods. The purpose of this review is to highlight the importance of Additive Manufacturing technique and also understand the effect of this process on the materials tested. During this work, the evolution of materials in the aerospace sector, the basic concept of AM technique, the application of the materials, the properties obtained when processing is done, the limitations and the scope for research are given.

Water sorption in epoxy networks is associated with deleterious physical effects such as swelling, hydrolysis, lowering of the Tg, cracking and crazing.Nonetheless, water uptake in epoxy coatings is poorly understood in relation to macromolecular structure. In this contribution, we study the effect of cure time (closely related to cross-linking density and free volume) on water uptake for a model epoxy-phenolic coating. Localised water uptake is then mapped with nanoscale lateral resolution using AFM-IR, and correlated to cross-linking density.
