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.

“…The inclusion of the GA increased the fracture toughness by 64% at 1.4 wt% particle loading. Therefore, while the GA is more effective than the CNT and 2D graphene sheets, its performance is not much different than 3D graphene foam [140][141][142][143][144][145]. The improvement because of the particles is in the decreasing order: graphene foam > graphene aerogel >graphene nanoplatelets > CNT.…”

A review on aerogel: 3D nanoporous structured fillers in polymer‐based nanocomposites

There have been a number of review papers on layered silicate and carbon nanotube reinforced polymer nanocomposites, in which the fillers have high aspect ratios. Particulate‐polymer nanocomposites containing aerogel with extremely low density, large open pores, and high surface area are also an important class of polymer nanocomposites. Thus, this article provides an overview on the effect of aerogel on mechanical and thermal properties of polymer‐based nanocomposites. Moreover, the preparation, history, classification, and characteristics of the aerogel are addressed. Among the polymer‐aerogel nanocomposites, various categories including silica and carbon aerogel‐polymer nanocomposites were discussed in detail. POLYM.

“…In recent years, there is a growing interest in renewably sourced materials in the polymeric materials field, due to the fluctuations in oil price and the increase in environmental concern. Biopolymers, extracted from renewable sources, can be classified into three main groups: extracted from biomass, such as polysaccharides and proteins; synthesized from bioderived monomers, such as polylactic acid; and those produced by organisms or bacteria, such as bacterial cellulose [1,2]. Sodium alginate is an algae-based anionic and hydrophilic linear polysaccharide, characterized by its excellent biocompatibility, biodegradability, non-toxicity, and low cost [3,4].…”

Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites

Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve material characteristics, the use of nanoreinforcements to prepare nanocomposites with enhanced properties, such as carbonaceous structures which could improve thermal and mechanical behavior and confer new functionalities, is being studied. In this work, graphene oxide was obtained from graphite by using modified Hummers' method and exfoliation was assisted by sonication and centrifugation, and it was later used to prepare sodium alginate/graphene oxide nanocomposites. The effect that different variables, during preparation of graphene oxide, have on the final properties has been studied. Longer oxidation times showed higher degrees of oxidation and thus larger amount of oxygen-containing groups in the structure, whereas longer sonication times and higher centrifugation rates showed more exfoliated graphene sheets with lower sizes. The addition of graphene oxide to a biopolymeric matrix was also studied, considering the effect of processing and content of reinforcement on the material. Materials with reinforcement size-dependent properties were observed, showing nanocomposites with large flake sizes, better thermal stability, and more enhanced mechanical properties, reaching an improvement of 65.3% and 83.3% for tensile strength and Young's modulus, respectively, for a composite containing 8 wt % of graphene oxide.
