Graphene-based artificial nacre nanocomposites

Abstract

With its extraordinary properties as the strongest and stiffest material ever measured and the best-known electrical conductor, graphene could have promising applications in many fields, especially in the area of nanocomposites. However, processing graphene-based nanocomposites is very difficult. So far, graphene-based nanocomposites exhibit rather poor properties. Nacre, the gold standard for biomimicry, provides an excellent example and guidelines for assembling two-dimensional nanosheets into high performance nanocomposites. The inspiration from nacre overcomes the bottleneck of traditional approaches for constructing nanocomposites, such as poor dispersion, low loading, and weak interface interactions. This tutorial review summarizes recent research on graphene-based artificial nacre nanocomposites and focuses on the design of interface interactions and synergistic effects for constructing high performance nanocomposites. This tutorial review also focuses on a perspective of the dynamic area of graphene-based nanocomposites, commenting on whether the concept is viable and practical, on what has been achieved to date, and most importantly, what is likely to be achieved in the future.

Role of Interface Interactions in the Construction of GO‐Based Artificial Nacres

“…The interlamellar interface mainly comprises the disordered collagen and noncollagenous proteins. [75] The former mainly contains utilization of large-size GO nanosheets, [76][77][78][79][80][81][82][83] annealing treatment under high temperature, [80,[84][85][86][87] and modulation of intrinsic GO chemical structure. The osteons are bonded with surrounding interstitial bone by the cement line (with thickness of 1-5 µm), which has higher mineralization and lower collagen content than the surrounding bone.…”

“…[51,58,90] Figure 2 shows that in the past decade, an increasing research effort has been made to improve the mechanical properties of graphene-based nanocomposites by various interfacial www.advmatinterfaces.de modifications. [48,75,[91][92][93][94] The interfacial crosslinking strategies contain hydrogen bonding, [95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111][112][113][114] ionic bonding, [81,[115][116][117][118] π-π interaction, [119][120][121] and covalent bonding. Inspired by nacre, a vast variety of highperformance GO-based nanocomposites and their reduced counterparts, including 1D fibers, 2D films, and 3D bulk materials, have been successfully constructed by interfacial crosslinking and building block toughening.…”

High‐Performance Nanocomposites Inspired by Nature

“…Extensive research has revealed the mechanism responsible for natural materials' properties and shows that high-performance structural materials could be fabricated via bioinspired strategies. [1][2][3][4][5][6][7][8][9][10] With the quest to develop novel bioinspired materials, it is essential to refine some basic scientific principles that can guide bioinspired fabrication.Recent research has indicated that the amplification of natural materials' mechanical properties far beyond those of the components that comprise them originates mainly from: i) a hierarchical micro-/nanoscale architecture and ii) abundant effective interface interactions. Here, we follow the roadmap of "discovery, invention, and creation," as shown in Figure 1, to give insight into the development of bioinspired structural materials.…”

Composite coating with synergistic effect of biomimetic epoxy thermoset morphology and incorporated superhydrophobic silica for corrosion protection

“…In order to facilitate the corrosion protection of various metallic substrates, versatile alternative practical coatings are being continuously developed such as conducting/ electroactive polymers, [10,11] conventional polymers containing filler with large aspect ratio [12,13] and polymer coatings with superhydrophobic surface [14,15]. Recently, great attention is paid to the potential of applications on bio-mimetic materials with super-hydrophobic surfaces structure due to their diverse potential and unprecedented hierarchical surfaces [16][17][18][19][20][21][22][23][24][25][26]. Moreover, the studies of anticorrosive polymer coatings with roughly superhydrophobic or biomimetic surface attracted intensive research interests [27][28][29][30][31][32][33][34].…”
