A critical review on the utilization of various reinforcement modifiers in filled rubber composites

Abstract

Presently, the development of high-performance filled rubber composites offers a new era in the industrial field of polymer research. This article reviews the utilization of various reinforcement modifiers on the successive property enhancement of rubber composites containing different commonly used fillers like silica, nanoclay, carbon nanotube, natural fibers, and so on. The practical importance of reinforcement modifiers in rubber technology is systematically described in the light of filler dispersion, processing, and mechanical properties of filled rubber compounds. A special emphasis is given on the mechanism of interaction between reinforcement modifiers and filler surface in filled rubber composites. Filler dispersion in the rubber matrix is the key parameter that controls the ultimate performance and rubber–filler interaction of filled rubber system. The use of some fixed reinforcement modifiers is an innovative way not only to solve the dispersion problem of filler particles but also to increase the reinforcing ability of most of the fillers in filled rubber products. Thus, the concept of reinforcement modifiers has the potential to facilitate further development of filler reinforcement technology for rubber-based composite materials.

A high toughness elastomer based on naturalEucommia ulmoidesgum

“…Surprisingly, HEUG‐85.6% had best mechanical strength and toughness despite its lower Ve , whose tensile strength up to 21.4 MPa, elongation at break up to 700%, fracture toughness up to 68.1 MJ m −3 , but Young's modulus was only 9.7 MPa. To the best of our knowledge, the toughness of HEUG‐85.9% cured by this vulcanization formula can rival that of NR 61 . The reasons for the excellent mechanical properties of HEUG‐85.6% will be discussed in detail in the next section.…”

Review on the Conceptual Design of Self-Healable Nitrile Rubber Composites

“…The mechanical properties of filled rubber composites are closely related to the nature of interfaces between the rubber matrix and filler. 19 As shown in Table 1 , the mechanical properties and cross-link densities of MGTR filled XNBR/6ZnO composites were lower than those properties of unfilled XNBR/6ZnO composites. This result was attributed to the shielding effect of the oxide present in the structure of MGTR, which considerably reduces the possibility of the ionic cross-link formation in the XNBR/6ZnO/MGTR network.…”

Recent advances of natural fibers based green rubber composites: Properties, current status, and future perspectives

“…In rubber chemistry, the achieved properties of filler reinforced rubber composites directly depend on dispersion ability of filler particles within the rubber matrix 14–16 . The hydrophilic nature of natural fibers has great contribution on the performance of natural fibers based rubber materials.…”
