Shear failure in supported two-dimensional nanosheet van der Waals thin films

Scalable van der Waals graphene films for electro‐optical regulation and thermal camouflage

“…Also, the impurity‐free structure of vdWGRfs was determined by XRD (Figure S6). It is important to note that the thickness of the vdWGRf cannot grow indefinitely, which is limited by the shear force 43 . With the loading content of graphene nanosheets increasing to ~75 mg m – 2 , the thickness stopped growing (Figure 2C).…”

“…It is important to note that the thickness of the vdWGRf cannot grow indefinitely, which is limited by the shear force. 43 With the loading content of graphene nanosheets increasing to $75 mg m -2 , the thickness stopped growing (Figure 2C). The thickness of vdWGRfs was around 136 nm, determined by SEM (Figure 2C), which was exactly in line with the theoretical calculation and thickness to achieve the theoretical maximum emissivity regulation of graphene film with 100-150 layers.…”

A conformal van der Waals graphene coating enabled high-performance piezo-ionic sensor for spatial, gesture, and object recognition

“…It is worth mentioning that the thickness of the vdWGR coating cannot grow infinitely because of the restriction of shear failure. 30 When the loading weight of graphene nanosheets reached 77 mg m −2 , no more graphene can be loaded and the sheet resistance of vdWGR reached the minimum (Fig. S3†).…”

Effect of bacterial growth stage on the response to two-dimensional nanomaterials

“…S1 †). 26,50 Monolayer thickness for the three materials increases in the order MoS 2 < MoSe 2 < GO, but among these three types of materials the thickness varies only ±20% of the average. Using the interlayer spacings in stacked films as a measure of fundamental monolayer thickness, MoS 2 is measured here as 0.59 nm by XRD (Fig.…”

“…S3B †), which is similar to previous studies. 50 GO interlayer spacing depends on its hydration state and is measured here by XRD in the nominally dry state to be 0.8 nm (Fig. S3C †), which is similar to the 0.7 nm reported in Nair et al 2012 under controlled low humidity conditions.…”
