Studies on the strength and wear resistance of tetrapod‐shaped ZnO whisker–reinforced rubber composites

Abstract

Zinc oxide whisker with a tetrapod shape was treated with a coupling agent using an orthogonal design and was mixed into the substrate of natural rubber to obtain the composites. The results of the experimental tests show that the tensile strength of the composites progressively increases with an increased amount of the related whisker. The experiments also indicate that the rubber reinforced by the tetrapod-shaped ZnO whisker is distinct isotropy. The wear tests demonstrate that the composites containing ZnO whisker appear to have good wear-resistance behavior.

ZnO nanostructures prepared from ZnO:CNT mixtures

“…ZnO tetrapods have also been mixed with rubber to form a composite. 26 The composite has improved tensile strength and wear resistance compared to natural rubber. 26 A number of synthesis methods have been reported for ZnO tetrapod nanorod structures, from evaporation of pure Zn 5,11-13 to carbothermal reduction of ZnO 10 or ZnCO 3 .…”

ZnO Tetrapods: Synthesis and Applications in Solar Cells

“…The bandgap energy and the electron affinities of ZnO are similar to TiO 2 , but its higher electron mobility compared to TiO 2 may overcome higher electron recombination in the TiO 2 -based dye sensitized solar cells (DSSCs), which is beneficial for solar cell performance. The ZnO porous networks are superior in providing electron extraction to one-dimensional (1D) nanorod structures or bulk materials as interconnections and functional components in photovoltaic devices [13][14][15][16][17], because nanotetrapods can always transport electrons in the direction perpendicular to the conductive substrate by directing the constituent arms in the four tetrahedral directions. The porous networks are also important in increasing the diffusion rate without increasing the recombination rate, and could therefore increase the efficiency of a photoelectrochemical energy conversion system.…”

Fabrication and Characterization of Cobalt Sensitized Nanostructure Zinc Oxide Thin Film Coated on Glass by Sol-Gel Spin Coating Using Trans-bis(acetylacetonato)-bis(4-methylpyridine)cobalt(III)

“…[23][24][25][26][27][28][29] Zinc oxide nanostructures with different morphologies have been fabricated. [30][31][32][33][34][35][36][37][38] Application of cobalt complexes in nanotechnology has been extensively studied due to their greater functional properties in chemical sensors, catalysis, and biosensors. [39,40] There have been reports on the application of cobalt complexes as either film or nanosize materials in fuel cells, oxygen reduction in fuel cell, ascorbic acid, and dopamine oxidation, detection of hydrogen peroxide, glucose sensing, and as energy storage.…”
