“…27,[100][101][102] Some of the important properties of graphene that have been reported so far include large surface to weight ratio (for example, 1 gram of graphene can cover several football elds), approximate elasticity of 1100 GPa, 103,104 fracture toughness of 125 GPa, 103,104 high thermal conductivity and high surface area (2630 m 2 g −1 ) [105][106][107][108][109][110][111] Since the fabrication of graphene, which consists of one or more graphite layers with SP 2 allotrope bonds of 2D carbon.

Biomimetic, Mechanically Strong Supramolecular Nanosystem Enabling Solvent Resistance, Reliable Fire Protection and Ultralong Fire Warning

“…34,43 Similarly, apart from the peak of B�O, a new peak that is assigned to B�O�C can also be observed (Figure 3h), indicating B-doping reaction in the rGO network. 44 The results of the XRD pattern of GO/MB paper after being burned can further demonstrate this conclusion (Figure S15). In fact, an atom-doped phenomenon of reduced GO sheets has been already discussed in previous works.…”

“…g ., COC and C­(O)O disappear after burned, while the peaks of CN and CN are visible (Figure g). It should be noted that the hexatomic ring structure of M·2B would decompose under a high-temperature environment induced by a butane torch flame; thus, the peaks of CN and CN are attributed to N-doping of the rGO network during the thermal decomposition process. , Similarly, apart from the peak of BO, a new peak that is assigned to BOC can also be observed (Figure h), indicating B-doping reaction in the rGO network . The results of the XRD pattern of GO/MB paper after being burned can further demonstrate this conclusion (Figure S15).…”

Thermoresponsive Conductivity of Graphene‐Based Fibers

“…In this sense, the well-recognized properties of graphene, such as large specific surface area (2630 m 2 g −1 ), electrical (10 8 S m −1 ), and thermal conductivities (5000 W m −1 K −1 ), and excellent mechanical properties (e.g., tensile strength of 130 GPa), make itself an attractive precursor and additive for material fabrication. [6,[8][9][10][11][12] Indeed, graphene-based composites have been fabricated recently as high performance smart materials with chemical, electronic, and mechanical responsive capabilities, among others. [2][3][4]6,13,14] Thermally responsive smart materials, or materials which exhibit a response to changes in temperature, have gained considerable interest for their promising applications in electronics.…”
