“…Liu et al. [ 61 ] treated GNPs by denatured SPI and then added them into polycarbonate (PC) matrix to fabricate polymer nanocomposites. Denatured fine SPI nanoparticles coated on the GNP surface very well and a stable GNP suspension was maintained for even several weeks, while the undenatured large SPI particles had poor effect on dispersing GNPs (Figure 6f).…”

Structural and compositional diversities of proteins generate a number of functions for fabricating novel and advanced materials. Recent progress in protein engineering endows flexible approaches and new functionalities, which makes the fabricated materials potentially applicable in a broad spectrum of fields. Such engineering strategies by applying proteins alone or together with other molecules derive numerous functional materials such as patterned nanometal materials/nanometallic compounds, well‐designed nanocomposites, etc. Advantages in materials’ tunability, property improvement (e.g., electronic and mechanical properties, etc.), functionalities, and biocompatibility have been demonstrated, thus providing alternatives to existing materials via conventional methods. This review summarizes and discusses the strategies of fabricating functional materials using proteins as the critical contributors. Benefiting from their versatility, proteins find their roles in engineering functional materials via acting as structure‐control agents, reaction agents, and battery components, which are emphasized in this review. The strategies of each group of functions are specifically detailed. Properties of protein‐engineered functional materials and their potential applications in the fields of microelectronics, energy storage and conversion, sensor devices, etc. are also reviewed.

“…To address the limitations of conventional conductive binders, we report a novel strategy using denatured soy protein (d-SP) to form a multifunctional surface coating on electrode nanoparticles. Our previous studies have demonstrated that d-SP is an effective surfactant for facilitating dispersion of graphitic materials, such as carbon nanotubes , and graphite nanoplatelets in water and even in a polymer matrix. More importantly, our recent work revealed that d-SP also presents great potential in being an advanced ion conductor for lithium ions .…”

Creation of three-dimensional (3D) porous nanostructured electrodes with controlled conductive pathways for both ions and electrons is becoming an increasingly important strategy and is particularly of great interest for the development of high-performance energy storage devices. In this article, we report a facile and environmentally friendly self-assembly approach to fabricating advanced 3D nanostructured electrodes. The self-assembly is simply realized via formation of a multifunctional protein coating on the surface of electrode nanoparticles by using a denatured soy protein derived from the abundantly prevalent soybean plant. It is found that the denatured protein coating plays three roles simultaneously: as a surfactant for the dispersion of electrode nanoparticles, an ion-conductive coating for the active materials, and a binder for the final electrode. More importantly, it is interestingly found that being a unique surfactant, the surface protein coating enables the self-assembly behavior of the electrode nanoparticles during the evaporation of aqueous dispersion, which finally results in 3D porous nanostructured electrodes. In comparison with the most classic binder, poly(vinylidene fluoride), the advantages of the 3D nanostructured electrode in terms of electrochemical properties (capacity and rate capability) are demonstrated. This study provides an environmentally friendly and cost-effective self-assembly strategy for fabrication of advanced nanostructured electrodes using electrode nanoparticles as the building block.

LithiumÀ sulfur (LiÀ S) batteries are a promising candidate for the next-generation energy storage system, yet their commercialization is primarily hindered by polysulfide shuttling and uncontrollable Li dendrite growth. Here, a protein-based Janus separator was designed and fabricated for suppressing both the shuttle effect and dendrite growth, while facilitating the Li + transport. The Li metal-protecting layer was a protein/MoS 2 nanofabric with high ionic conductivity and good Li + affinity, thus capable of homogenizing the Li + flux and facilitating the Li + transport. The polysulfide-trapping layer was a conductive protein nanofabric enabling strong chemical/electrostatic interactions with polysulfides. Combination of the two layers was achieved by an integrated electrospinning method, yielding a robust and integral Janus separator. As a result, a long-lived symmetric Li j Li cell (> 700 h) with stable cycling performance was demonstrated. More significantly, the resulting LiÀ S battery delivered greatly improved electrochemical performance, including excellent rate capacity and remarkable cycle stability (with a low decay rate of 0.063 % per cycle at 0.5 A g À 1 over 500 cycles). This study demonstrates the effectiveness of the Janus separator configurations for simultaneously addressing the shuttle effect and dendrite growth issues of LiÀ S batteries and broadens the applications of electrospinning in electrochemistry community.
