Polyamide/Carbon Nanoparticles Nanocomposites: A Review

Abstract

This review is designed to be a comprehensive source for polyamide (PA) nanocomposite research, including fundamental structure/property relationships, manufacturing techniques, and applications of these materials. This work presents the scientific framework for the advances in PA nanocomposite containing carbon nanofiller, and different methods applied in order to synthesis them. This review focuses on the scientific principles and mechanisms in relation to the methods of processing and manufacturing. A comprehensive discussion on technology, modeling, characterization, processing, manufacturing, and applications have been done. The processing and properties of PA nanocomposites with carbon nanofillers are investigated. In addition, the mechanical properties and morphology changes of PA with the incorporation of nanoparticles are described. POLYM. ENG. SCI., 57:475-494, 2017.

The effect of MWCNT on dynamic mechanical properties and crystallinity of in situ polymerized polyamide 12 nanocomposite

“…The strength of nano filler‐polymer interactions is another key parameter to obtain a nanocomposite with interesting mechanical and physical chemistry properties . Nevertheless, enhancing the toughness of polymers by nano fillers is still in debate …”

“…20 Nevertheless, enhancing the toughness of polymers by nano fillers is still in debate. 21 Many studies were done on improving the MWCNT dispersion in a polymer matrix and lowering the MWCNT loading to overcome the dispersion and distribution problem. Techniques including high shear processing, sonication during extrusion, and surface functionalization have been applied.…”

Reactive Extrusion of Polyamide 6 Using a Novel Chain Extender

“…It is moderately priced and with excellent mechanical properties and chemical resistance. PA6 has been mainly used in the textile industry as a substitute of natural fibres but has found increased application in the automotive industry (gears, bearings and fittings), packaging and in the manufacture of parts and products which must be tough, impact resistant and abrasion resilient such as power tools and electronic housings and the large variety of threads, ropes and filaments [2][3]. PA6 has found even greater application following the breakthrough by researchers at Toyota who in the 1980s compounded it with nano-clays to pave the way for the development of polymer nanocomposites [4].…”

Eco‐friendly produced lightweight structural graphene/polyamide 12 nanocomposite: Mechanical performance and the controlling microstructural mechanisms

“…The bulk properties of graphene/PNCs is mainly dictated by the structural characteristics of graphene that control its intrinsic properties and the interfacial interactions between graphene nanosheets and polymer matrix . Stronger interfacial interactions between graphene and polymer matrix can be usually achieved by improving the dispersion and distribution of graphene nanosheets in the polymer matrix, integrating graphene nanosheets with larger aspect ratio within the polymer matrix and enhancing covalent or non‐covalent bonding at the filler‐matrix interface through chemical modification of the graphene nanosheets and/or the polymer matrix . Conversely, the graphene synthesis strategy strongly affects its structural characteristics .…”
