Considering industrial requests, it has become a hot issue to prepare advanced rubber composites with high strength and great toughness. Despite enhanced strength and stiffness, rubber composites suffer markedly reduced extensibility and toughness. Herein, a novel interfacial strategy is proposed to fabricate amine‐modified montmorillonite (MMT)/hydrogenated nitrile butadiene rubber composites by designing in situ ionic bond interfaces. The well‐distributed interfaces, which are composed of protonated amine groups on the MMT surfaces and electronegative methacrylic acid (MA), were constructed by adding a slurry with a small amount of MMT and MA to rubber. After the vulcanization, self‐polymerization of MA developed nanoparticles and grafting structures onto rubber chains to bond MMT by strong ion attractions. Although the crosslinking degree of rubber was reduced, the dispersion of MMT and its interfacial interactions with rubber were improved remarkably, as demonstrated by morphology observations, dynamic mechanical analysis and infrared spectra. As a result, the strength, modulus, elongation, toughness and gas barrier properties of the rubber composites were simultaneously strikingly improved relative to composites without MA modifiers. We believe that this work provides a promising methodology of fabricating high‐performance rubber composites. © 2019 Society of Chemical Industry

“…The results showed that the thermal conductivity of the silicon was improved by the addition of carbon-based nanofillers. Additionally, the role and influence of graphene and its derivatives in elastomer nanocomposites have been well documented previously [ 20 , 21 , 22 , 23 , 24 ]. The graphene/elastomer nanocomposite demonstrated improved mechanical properties, dynamic mechanical properties, and thermal stability [ 25 ].…”

In this paper, the mechanical properties, thermal stability, and transparency of ethylene–propylene copolymer (EPC) elastomer modified with various weight percentages (1, 3, and 5 wt.%) of SiO2 nanofillers have been studied. The nanocomposites were prepared via a simple melt mixing method. The morphological results revealed that the nanofillers were uniformly dispersed in the elastomer, where a low concentration of SiO2 (1 wt.%) had been added into the elastomer. The FTIR showed that there are interfacial interactions between EPC matrix and silanol groups of SiO2 nanoparticles. Moreover, by the addition of 1 wt.% of SiO2 in the EPC, the tensile strength and elongation at break of EPC increased by about 38% and 27%, respectively. Finally, all samples were optically transparent, and the transparency of the nanocomposites reduced by increasing the content of SiO2 nanoparticles.

“…Tannic acid acted as a dispersant for graphene oxide and was responsible for the synergistic action of all participating components. In another study, highly efficient car tires were produced from a similar material, in this case based on styrene–butadiene–rubber, graphene oxide, and epigallocatechin-gallate ( Figure 4 n–p) [ 99 ]. The enhanced tire efficiency ( Figure 4 p) was evidenced by lower rolling resistance ( Figure 4 o) and based on the specific roles of tannin in the material.…”

Tannin-Based Hybrid Materials and Their Applications: A Review

et al. 2020

Tannins are eco-friendly, bio-sourced, natural, and highly reactive polyphenols. In the past decades, the understanding of their versatile properties has grown substantially alongside a continuously broadening of the tannins’ application scope. In particular, recently, tannins have been increasingly investigated for their interaction with other species in order to obtain tannin-based hybrid systems that feature advanced and/or novel properties. Furthermore, in virtue of the tannins’ chemistry and their high reactivity, they either physicochemically or physically interact with a wide variety of different compounds, including metals and ceramics, as well as a number of organic species. Such hybrid or hybrid-like systems allow the preparation of various advanced nanomaterials, featuring improved performances compared to the current ones. Consequently, these diverse-shaped materials have potential use in wastewater treatment or catalysis, as well as in some novel fields such as UV-shielding, functional food packaging, and biomedicine. Since these kinds of tannin-based hybrids represent an emerging field, thus far no comprehensive overview concerning their potential as functional chemical building blocks is available. Hence, this review aims to provide a structured summary of the current state of research regarding tannin-based hybrids, detailed findings on the chemical mechanisms as well as their fields of application.
