“…While SB has been implemented for a number of nonmedical applications, such as marine coatings, batteries, and oil-water separations, this review will focus specifically on its biomedical uses. [35][36][37] Furthermore, though SB has shown an ability to prevent bacterial fouling, this will not be discussed in the context of this review and the reader is instead encouraged to further examine existing reviews on this topic. [38][39][40][41][42] Herein, we will specifically focus on the history of SB use in biomaterials design, the underlying chemistry giving rise to SB motifs, the methods for grafting of SB coatings, and finally a discussion on the application of SB materials spanning membranes, nanoparticles (NPs), selectively binding surfaces, and gene delivery vectors.…”

Protein fouling can render a biomedical device dysfunctional, and also serves to nucleate the foreign body reaction to an implanted material. Hydrophilic coatings have emerged as a commonly applied route to combat interface-mediated complications and promote device longevity and limited inflammatory response. While polyethylene glycol has received a majority of the attention in this regard, coatings based on zwitterionic moieties have been more recently explored. Sulfobetaines in particular constitute one such class of zwitterions explored for use in mitigating surface fouling, and have been shown to reduce protein adsorption, limit cellular adhesion, and promote increased functional lifetimes and limited inflammatory responses when applied to implanted materials and devices. Here, we present a focused review of the literature surrounding sulfobetaine, beginning with an understanding of its chemistry and the methods by which it is applied to the surface of a biomedical device in molecular and polymeric forms, and then advancing to the many early demonstrations of function in a variety of biomedical applications. Finally, we provide some insights into the benefits and challenges presented by its use, as well as some outlook on the future prospects for using this material to improve biomedical device practice by addressing interface-mediated complications.

“…not plastic crystals) that could be an additional advantage for electrolyte applications. Those zwitterionic additives have been used to promote Li + dissociation in polymer and gel polymer electrolytes, [19][20][21] where they are believed to facilitate the dissociation of Li ions from the polymer backbone and enhance the Li ion conductivity and Li + ion transference number (the fraction of charge carried by the Li + ). [22][23][24][25][26][27][28] Furthermore, it was reported that ZI addition can promote the amorphous phase and reduce the polymer crystallinity, also resulting in increasing Li ion mobility.…”

“…The lithium nickel cobalt manganese oxide (NCM)/graphite cell showed greater capacity and more stable cycling with ZI additives. 20 Improved performance of lithium ion batteries has also been achieved by the addition of a pyrrolidinium sulfonate ZI into ionic liquid electrolytes (N-methyl-N-propylpyrrolidinium bis(-uorosulfonyl)imide ([C 3 mpyr][FSI])/lithium bis(tri-uoromethylsulfonyl)imide (LiTFSI)), which was attributed to a decrease in the interfacial resistance between the electrolyte and cathode. This ZI-based IL electrolyte presented high thermal stability up to 300 C, which means that the addition of the ZI did not change the thermal stability of the IL.…”

Silicon is considered as a promising candidate for anode materials due to its ultrahigh theoretical capacity and natural abundance. However, the commercialization is severely hampered by the large strain and short cycle life. Herein, we have synthesized a reversible polyelectrolyte/polyzwitterion coacervate framework to achieve high‐performance silicon anodes with high initial Coulombic efficiency (ICE) and stable cyclability. Such coacervate framework is formed via in‐situ free radical polymerization of zwitterionic 2‐methacryloyloxy ethyl phosphorylcholine (MPC) with polyacrylic acid (pAA) during heating the slurry. The resulting pAA/pMPC coacervate framework presents excellent adhesion, thermal stability, and negligible swelling in the electrolyte. Comparing with pAA, pAA/pMPC0.1 coacervate framework binder exhibits superior performance during charge/discharge. The ICE is improved from 84.41%, to 87.61%. After 250 cycles, the specific capacity of pAA/pMPC0.1 silicon anode is 1678 mAh g‐1 with a retention of 78% while the pAA silicon anode completely failed after less than 200 cycles. Such improvement is ascribed to the structural integrity of the electrode endowed by the self‐healing ability of pAA/pMPC coacervate framework. This work not only offers a feasible method to in‐situ construct coacervate framework with self‐healing capability to achieve high‐performance silicon anodes but also a compatible electrode preparation process for other high‐capacity materials.
