Supramolecular elastomers have attracted extensive attention due to their excellent mechanical properties. Herein, inspired by the concept of a dual cross‐linked network structure, a dual‐component coordination supramolecular elastomer is prepared via photopolymerization of three monomers combined with zinc ion (Zn2+)‐crosslinked low molecular weight polyacrylic acid (PAA). The covalent network of three monomers serves as a soft component forming the supporting network. The network of Zn2+ crosslinked low molecular weight PAA forms the hard component. The covalent network is crosslinked and locked by the coordinated network. This compact network contributes to improving the comprehensive mechanical properties. The optimal elastomer is that the molar ratio of carboxylic of low molecular weight PAA with Zn2+ is 1:0.5. The tensile and compression stress of the optimal elastomer are 4.08 and 6.90 MPa, respectively. The loading–unloading cycles can reach 1000 times without fracture. The self‐recovery ratios of the tensile and compression modes reaches 80% and 95%, respectively.

“…[12][13][14] Among these, metal-coordination bonding is considered the strongest of all noncovalent interactions; 15,16 it has been used extensively in supramolecular systems for crosslinking because of its stability, reversibility, and multifunctionality. Wu and his coworkers [20][21][22][23] investigated crosslinked rubber connected by coordination bonding in nonsolution systems for the first time.

“…Then, Ibarra et al 24 found that both coordination bonds and ionic bonds led to the formation of a crosslinking structure in a carboxylated nitrile rubber-copper sulfate (CuSO 4 ) system. 21,23 Additional Supporting Information may be found in the online version of this article. In those systems studied, NBR was usually selected as gum curing agent by the coordination crosslink of ─CN groups and a variety of transitional ions, such as copper ions, cobalt ions, and rare earth ions.…”

In this study, aluminum sulfate 18-hydrate [Al 2 (SO 4 ) 3 Á18H 2 O] particles of different sizes, which were obtained via high-energy ball-milling technology, were successfully compounded with acrylonitrile-butadiene rubber (NBR) to fabricate crosslinked rubber composites. The results suggest that high-energy ball milling had no significant change on the crystal structure of Al 2 (SO 4 ) 3 Á18H 2 O, but it significantly reduced the particle size. The effects of the particles size on the coordination crosslinking behaviors and mechanical properties of the NBR-Al 2 (SO 4 ) 3 Á18H 2 O composites were fully explored. The coordination crosslinking reaction was demonstrated to occur between the nitrile group (─CN) and Al(III). Moreover, with the decreasing particle size, the composites achieved a better interfacial adhesion and more crosslinking points, and this led to significant increases in the crosslinking density and the mechanical properties.

“…Our previous works have found that certain inorganic metal salts could interact directly with matrix polymers. Anhydrous copper sulfate (CuSO 4 ) and zinc chloride (ZnCl 2 ) proved to be efficient crosslinking agents in acrylonitrile rubber and acrylate rubber when incorporated into the matrices . In the process of hot‐pressing, coordination crosslinking reaction took place between metal cations (Cu 2+ and Zn 2+ ) and polar groups (CN and COOR), resulting in three‐dimensional crosslinking networks.…”

Acrylonitrile‐butadiene‐styrene (ABS)/nitrile butadiene rubber (NBR) blends in the composition of 90/10 filled with anhydrous cobalt chloride (CoCl2) particles are successfully prepared to investigate the impact of CoCl2 on the composites properties. The coordination reaction between CoCl2 particles and nitrile groups in both ABS and NBR phase is generated by heat pressing at 190 °C for 15 min. Fourier transform infrared and X‐ray photoelectron spectroscopy are used for the investigation of the coordination reaction. Scanning electron microscopy and transmission electron microscopy are utilized to study microstructure of the composites. It is found that the solid‐state coordination reaction takes place between nitrile groups (‐CN) and cobalt ions (Co2+), which leads to increases in mechanical properties and glass transition temperature (Tg). The tensile strength and impact strength of ABS/NBR/CoCl2 composites are improved by about 14% and 29%, respectively, in contrast to that of pure ABS, with the CoCl2 loading in the range of 5–7 wt %. The studies of scanning electron microscopy and transmission electron microscopy demonstrate that the discrete NBR components are dispersed uniformly in ABS phase and the CoCl2 particles tend to disperse in NBR phase, which promotes the toughness of the composites. © 2018 Wiley Periodicals, Inc.
