A homogenous composite material with increased tensile strength comprising 2-dimensional nano-sheets exfoliated from a 3-dimensional layered material mixed in a liquid non-Newtonian viscoelastic material to produce the homogenous composite material; and a process for making the same.

Viscoelastic conductive nanomaterial-polymer nanocomposites and sensing devices comprising the composite material

A process for producing conductive composites, the process comprising the steps of soaking a polymer in an organic solvent and applying energy; soaking the polymer in a solution of conductive nano-material dispersed in an organic solvent:water mixture and applying energy, so that conductive nano-material is incorporated into the polymer structure; washing the conductive nano-material-incorporated polymer in deionized water and applying energy; and drying the washed conductive nano-material-incorporated polymer to produce the conductive composite, wherein the conductive composite incorporates conductive nano-material throughout the structure of the polymer without affecting the integrity of the properties of the polymer.

Sensitive, high-strain, high-rate, bodily motion sensors based on conductive nano-material-rubber composites

The invention provides a process for exfoliating a 3-dimensional layered material to produce a 2-dimensional material, said process comprising the steps of mixing the layered material in a solvent to provide a mixture; applying energy, for example ultrasound, to said mixture, and removing the energy applied to the mixture, such that sedimentation of the 2-dimensional material out of solution as a weakly re-aggregated, exfoliated 2-dimensional material is produced. The invention provides a fast, simple and high yielding process for separating 3-dimensional layered materials into individual 2-dimensional layers or flakes, which do not strongly re-aggregate, without utilising hazardous solvents.
