Synergistic effect of carbon nanofiber decorated with iron oxide in enhancing properties of styrene butadiene rubber nanocomposites

Abstract

Elastomer nanocomposites reinforced with carbon nanofiber (CNF) decorated with metal nanoparticles exhibit excellent thermal, mechanical, and magnetic properties with low volume fraction of the reinforcement. Generally, metal nanoparticles are used to modify the surface of CNF, to improve their dispersion and contact resistance in the polymer matrix. In this study, Fe 2 O 3 metal nanoparticles were decorated on CNF by electrostatic attraction via a green and facile solution-based method. Interestingly, the CNF decorated with Fe 2 O 3 (CNF-Fe 2 O 3 )/elastomer improved both the tensile strength and the fatigue property of plain CNF/elastomer by as much as 57.2% and 27.2%, respectively. Moreover, the CNF-Fe 2 O 3 /elastomer exhibited superior thermal conductivity, a twofold enhancement compared with carbon fibers. The elastomer nanocomposites consisting of CNF-Fe 2 O 3 also exhibited enhanced magnetic properties due to synergies between the Fe 2 O 3 nanoparticles and the CNF. The elastomer nanocomposites prepared with CNF-Fe 2 O 3 will open significant new opportunities for preparing advanced elastomer nanocomposites for future engineering applications.

Characterization of eco-friendly processing aids for styrene butadiene rubber composites with silica

“…where n is the number of cycles, c is the crack length, and G is the tear energy. In equation (2), the fatigue crack growth is proportional to the tear energy, which indicates that when the tear energy is increased, the fatigue life is decreased. The M-A-S/SBR composites showed a remarkable reduction in the crack length after 10,000 cycles, and the fatigue crack growth of the rubber composites with M-A-S was decreased by more than 13% compared to that of the reference.…”

“…In the case of rubbers such as styrene butadiene rubber (SBR), which does not undergo strain-induced crystallization, various fillers have been used to improve the mechanical, thermal, and electrical properties as well as the processability and to reduce the cost of nearly all types of industrial rubbers. [1][2][3][4][5] Among them, 4,5 carbon black (CB) is considered as an important filler to enhance the hardness, tear strength, high tensile strength, and abrasion resistance of weak pure rubbers. However, in an effort to obtain the required characteristics and reduce the cost, CB decreases the rolling resistance and wet traction of the tire compounds.…”

Novel green composites from styrene butadiene rubber and palm oil derivatives for high performance tires

“…Rubbers have been used as viscoelastic polymers for applications in a wide range of industrial fields, especially the tire industry, by adding diverse fillers . Among the various fillers, carbon black (CB) is still widely used as a reinforcing filler to enhance abrasion and high tensile strength. However, CB also reduces wet traction and rolling resistance in tire tread compounds.…”
