“…Later, a new acrylonitrile‐based polymer, poly(acrylonitrile‐butyl acrylate) (PANBA), was introduced into graphene platelets as a binder in a lithium‐ion battery (LIB). [ 82 ] Graphene was the first conductive nanofiller used in a conventional water‐dispersed polymer and applied as a binder for LIB. These novel nanocomposites were prepared by in situ emulsion polymerization and were well dispersed and stable for a minimum of 6 months.…”

Polymer composite materials fabricated from acrylonitrile-derived polymers (such as polyacrylonitrile, nitrile butadiene rubber, styrene-acrylonitrile, acrylonitrile butadiene styrene) with suitable fillers have found tremendous applications due to their highly desirable properties. Graphene, a versatile 2D carbon nanomaterial, with extraordinary properties has been adopted as an effective filler component of a wide range of acrylonitrile-based polymer composites. The modified and functionalized graphene-based nanomaterials were incorporated into the acrylonitrile-based polymer matrix to enhance their various properties. In contrast to conventional 1D carbon nanoparticles, the incorporation of this graphene into the polymer matrix resulted excellent improvement in mechanical, electrical, rheological, and thermal, as well as frictional properties. This has offered advances in diverse applications such as sensors, flexible electronics, Li-S battery, damping, structural, microwave shielding, aircraft, spacecraft, automobile, and so forth. Particularly, the excellent EMI (Electromagnetic interference) shielding ability of these acrylonitrilebased polymer/graphene composites has been explored widely in microelectronics. This review focuses on the recent progress and new strategies in the development of different acrylonitrile-based polymer/graphene nanocomposites.

“…The traditional polyvinylidene fluoride (PVDF) binder is widely applied in LIBs because of its good adhesion and wide electrochemical window, but nonfunctional PVDF exhibits a poor obstacle to the shuttling of polysulfides when used in Li–S battery cathodes . In recent years, some advanced binders, such as ductile binders, water-based binders, , and conductive binders, − have been developed to improve comprehensive performance of LIBs. With the development of the intrinsic self-healing polymers, whose self-healing properties are usually realized by the reversibility of dynamic chemical bonds (such as disulfide bonds, , hydrogen bonds, and acylhydrazone bonds , ), a smart self-healing polymer binder was synthesized, mainly used for the silicon (Si) anodes of LIBs at present.…”

Lithium−sulfur (Li−S) batteries have been the focus of new energy due to their excellent energy density, but the large volume changes in sulfur cathodes and the shuttle of polysulfides seriously hinder their further development. Therefore, solving both the abovementioned problems is the key to the widespread applications of Li−S batteries. Here, a smart selfhealing polyurethane binder (PUB) with sulfur fixation ability is successfully developed for sulfur cathodes. In this design, aromatic disulfide bonds are introduced into the PUB matrix and cooperated with hydrogen bonds in the matrix to provide the self-healing property. The PUB can ensure the sulfur cathode an integrated physical structure by autonomously healing the microcracks caused by volume changes. The sulfur-fixing groups in the PUB can effectively absorb the polysulfides in the electrochemical reaction to suppress the shuttling effect. As a result, the Li−S batteries exhibit a high electrochemical capacity of 1269.7 mA h g −1 and a small fading rate of 0.04% per cycle at 2 C for 500 cycles. Hence, the PUB with dual functions of self-repair and sulfur fixation can effectively stabilize the electrode structures of Li−S batteries and guarantee their electrochemical performance.
