Polymeric nanocomposites reinforced with nanowhiskers: Design, development, and emerging applications

Abstract

<jats:p> This article provides insights into nanowhisker nanofiller particles, different categories of polymer/nanowhisker nanocomposites, and broad span of applications. Nanowhiskers are hierarchical needle-like elementary crystallites, often used as nanofillers in polymers. Cellulose, chitin, zinc oxide, fullerene, and aluminum nitride-based nanowhiskers have been employed in matrices. Inclusion of organic and inorganic nanowhiskers in polymers has enhanced thermal conductivity, electrical conductivity, thermal stability, water resistance, and other physical properties of nanocomposites. Polymer/nanowhisker nanocomposites have found technical applications in supercapacitors, sensors, anticorrosion agents, antibacterial agents, and drug delivery systems. Future research directions for potential applications rely on material design, nanowhisker functionalization, better dispersion, better reinforcement, and better processing techniques. </jats:p>

Current Advances in the Roles of Doped Bioactive Metal in Biodegradable Polymer Composite Scaffolds for Bone Repair: A Mini Review

“…In addition, because the dopant is closely combined with the matrix, it is difficult to pull the dopant out by stress, thus achieving the effect of strengthening and toughening. [144] Shuai et al blended MgO NPs with PLLA matrix to improve the mechanical properties of the PLLA scaffolds. MgO NPs, as the nucleating agent, can improve the crystallinity of PLLA, thus improving the mechanical properties of the scaffold.…”

High‐strain‐rate mechanical performance of particle‐ and fiber‐reinforced polymer composites measured with split Hopkinson bar: A review

“…[1][2][3][4][5][6][7][8] Polymer composites, which can be designed with improved properties in comparison with a neat polymer, have similarly been attracting significant attention as suitable replacements in high-demand applications. [1,[9][10][11][12][13][14][15][16][17][18] In many industrial sectors, such as aerospace, automotive, military, marine, and civil engineering, materials undergo high-rate dynamic loads; thus, the evaluation of their dynamic mechanical response, under compression, tension, torsion, shear, and bending, is of great importance. [19,20] Several reviews on the impact testing of composites, at different strain rates, are available in the literature.…”

A review of current knowledge and future trends in polymer/boehmite nanocomposites

“…Inorganic nanoparticles have been used with the polymeric matrices to enhance the technical relevance. 1 Inorganic nanoparticles have high surface area and several beneficial features, however have the tendency to aggregate. 2,3 The inorganic nanoparticles containing aluminum oxide are low-cost, non-toxic, and have fine physical and chemical characteristics.…”
