“…The first being one of the simplest forms of nanocomposite strain sensors, mixed-phase systems [155][156][157]. Through this methodology, nanosheets are incorporated into an elastic [157][158][159][160], or ionic gel [161][162][163], polymer matrix either through solution-solution or powder-solution mixing. Regardless of the type of mixing, the basis of the process involves the mixing of nanosheets and polymers in the liquid phase [164][165][166][167].…”

“…The resultant mixture is then generally left to dry out in a mould, with a solid film of polymer now embedded with nanosheets formed after all the solvent has been removed [164][165][166][167]. However, for hydrogel systems, mix-phase nanocomposites form a soft gelated material that is swollen with water once all materials have been added [162,[168][169][170][171][172][173][174][175]. The second form of nanocomposite to be analysed are layer deposition or coated nanocomposites.…”

Nanotechnology has led to the realisation of many potential Internet of Things devices that can be transformative with regards to future healthcare development. However, there is an over saturation of wearable sensor review articles that essentially quote paper abstracts without critically assessing the works. Reported metrics in many cases cannot be taken at face value, with researchers overly fixated on large gauge factors. These facts hurt the usefulness of such articles and the very nature of the research area, unintentionally misleading those hoping to progress the field. Graphene and MXenes are arguably the most exciting organic and inorganic nanomaterials for polymer nanocomposite strain sensing applications respectively. Due to their combination of cost-efficient, scalable production and device performances, their potential commercial usage is very promising. Here, we explain the methods for colloidal nanosheets suspension creation and the mechanisms, metrics and models which govern the electromechanical properties of the polymer-based nanocomposites they form. Furthermore, the many fabrication procedures applied to make these nanosheet-based sensing devices are discussed. With the performances of 70 different nanocomposite systems from recent (post 2020) publications critically assessed. From the evaluation of these works using universal modelling, the prospects of the field are considered. Finally, we argue that the realisation of commercial nanocomposite devices may in fact have a negative effect on the global climate crisis if current research trends do not change.

This work presents a design of a unique “roller wheel” structure combining rigid MXene and flexible liquid metal (LM), aiming to construct an epoxy composite coating with simultaneous advanced mechanical strength and lubrication properties. The antiwear property of the epoxy composites is improved by 72.8% when the LM is 0.5 wt% and MXene is 0.03 wt%. The incorporation of LM‐MXene improved the mechanical properties of the epoxy composite coating, resulting in an approximately 136.6% increase in elastic modulus. The unique “roller wheel” structure provides additional mechanical support and leads to lower adhesion between the MXene layers and LM. As a result, LM reduces the stripping and sliding of the interface between MXene layers during the friction process, further enhancing the lubrication performance of the epoxy composite coating.
