An application‐oriented roadmap to select polymeric nanocomposites for advanced applications: A review

Abstract

Polymeric nanocomposites are the materials incorporating nanosized inclusions into the polymer matrixes. The result of the addition of nanoparticles/fibers is a drastic improvement in properties that may include mechanical, electrical, thermal conductivity, or even the acoustical properties. Polymer nanocomposites have spawned huge interest for the development of high‐performance products such as lightweight sensors, thin‐film capacitors, batteries, flame retardant products, biodegradable and biocompatible materials, and so on. The field of polymer nanocomposites has been at the forefront of research in the polymer community for the past few decades and an extremely large number of scientific papers have been published. Nevertheless, application‐oriented guidelines for selecting the ecofriendly nanocomposites for advanced industrial applications are missing in the state of the art. This review article summarizes the current state‐of‐the‐art polymeric nanocomposites, highlighting prominent nanofillers categorized based on their applications, origins, dimensional characteristics, and so on. Each filler type contains a short description of its main feature together with the most relevant and potential applications. To address the global concern about nondegradable wastes, novel green alternatives of each nanofiller type are discussed. Special attention is also given to the biocompatibility properties of the composites. This study provides a state‐of‐the‐art road map to select multifunctional polymeric nanocomposites from huge varieties for advanced industrial applications.

Effect of silica nanoparticles on physical, mechanical, and wear properties of natural fiber reinforced polymer composites

“…However, beyond 3 wt% silica nanoparticles loading the flexural strength start decreasing, which may be attributed to the increased filler-fiber interaction, and increase in void content may cause a weak load transfer mechanism between filler and matrix. [13,25] A similar result for flexural strength was reported for silica nanoparticles loaded sisal-Kevlar fiber reinforced hybrid epoxy composites by M. S. Chowdary et al, [33] where the highest flexural strength was observed for 4 wt% silica nanoparticles and decreased with further increase in silica nanoparticles loading. Figure 6 presents the values of impact energy of the silica nanoparticles added composites.…”

“…[10] It has been found that the inclusion of nanoparticles enhances various properties of polymer composite, such as superior toughness and mechanical strength, excellent electrical and thermal properties, outstanding flame retardancy, and a more significant barrier to moisture and gases. [11][12][13] Several researchers studied the influence of silica nanoparticles on physical, tribiological, mechanical and thermo-mechanical characteristics of synthetic fiber reinforced polymer composites. [14][15][16] Indeed, synthetic fibers based polymer composites performed better, but nowadays, these composites are continuously questioned regarding their eco-friendliness.…”

Development and characterizations of ultra‐high molecular weight EPDM/PP based TPV nanocomposites for automotive applications

“…Where mechanical properties have been examined, they appear to be improved by the addition of a small amount of clay, but are decreased with larger amount of clays. [ 17–20 ]…”

“…Where mechanical properties have been examined, they appear to be improved by the addition of a small amount of clay, but are decreased with larger amount of clays. [17][18][19][20] The silica nano fillers (especially SiO 2 nano particles) have higher aspect ratio than typical microscopic aggregates and it is attractive for polymer reinforcement. Polymer-clay nanocomposites had shown drastic enhancement in mechanical properties (modulus and TS), thermal properties (heat resistance and flammability), and barrier properties.…”
