“…All of the layered SANd(III) papers displayed a perfect combination of high tensile , and Young's modulus of 5.2±0.2 GPa, which were considerably higher than those of other SA-based papers. 40,41 The ultimate strength of the layered SA-Nd(III)-1 paper was also close to that of the natural nacre (130 MPa), and its toughness was higher than that of natural nacre (1.8 MJ·m −3 ). 42 Moreover, different SA concentrations rendered varying mechanical strengths.…”

a Inspired by the heterogeneous architectures of biological composites, mimicking the hierarchical structure of nacre is a powerful strategy to construct high-performance materials. This paper presents a lightweight and nacre-like hierarchical paper which was fabricated via lanthanide ions coordination. Sodium alginate (SA) biopolymers and lanthanide ions (Nd 3+ , Gd 3+ , Ce 3+ and Yb 3+ ) were used as ideal building blocks and connection points, respectively. SA biopolymers and lanthanide ions rapidly self-assembled into an aligned hydrogel. The synthesized hydrogel was subsequently dried to form layered alginate-based papers. The formation mechanism of the layered paper was investigated and demonstrated that lanthanide ions coordination can produce the hierarchical structure. The as-prepared layered SA-Nd(III) nanopaper exhibited high strength of 124.2±5.2 MPa, toughness of 8.2±0.4 MJ·m −3 , and Young's modulus of 5.2±0.2 GPa, as well as excellent resistance to solvents. Owing to their outstanding mechanical properties and easy and fast fabrication, the layered SANd(III) papers demonstrated a potential application in the fields of biomaterials. This new strategy based on lanthanide ion coordination, can also be used to construct integrated, high-performance, and biopolymer materials.

“…Moreover, MGO/sodium alginate exhibited a much greater tensile strength and Young's modulus than those of GO/sodium alginate due to improved electrostatic interactions between sodium alginate and MGO. [82] As mentioned earlier, the hydrophilicity of alginate is very high. Moisture absorption studies showed that the moisture uptake was much lower for GO/sodium alginate and MGO/ sodium alginate than for sodium alginate.…”

Since its discovery in 2004, derivatives of graphene have been developed and heavily investigated in the field of tissue engineering. Among the most extensively studied forms of graphene, graphene oxide (GO), and GO/ polymer-based nanocomposites have attracted great attention in various forms such as films, 3D porous scaffolds, electrospun mats, hydrogels, and nacre-like structures. In this review, the most actively investigated GO/ polymer nanocomposites are presented and discussed, these nanocomposites are based on chitosan, cellulose, starch, alginate, gellan gum, poly(vinyl alcohol) (PVA), poly(acrylamide), poly(e-caprolactone) (PCL), poly(lactic acid) (PLLA), poly(lactide-co-glycolide) (PLGA), gelatin, collagen, and silk fibroin (SF). The biological and mechanical performance of such nanocomposites are comprehensively scrutinized and ongoing research questions are addressed. The analysis of the literature reveals overall the great potential of GO/ polymer nanocomposites in tissue engineering strategies and indicates also a series of challenges requiring further research efforts.
