Porous materials comprising two-dimensional nanomaterials


Graphene sponge

V Babenko, N Grobert
A method to make a metal composite containing high-quality graphene (or other 2D-nanomaterial), using industry standard CVD processes The Oxford technique produces a metal composite material with attractive mechanical properties, corrosion resistance and conductivity enhanced by the high quality graphene scaffold. Subsequent metal etching results in a graphene foam (or other 2D nanomaterial foam;) a unique light weight 2D material with high surface area and high conductivity.

For faster, larger graphene add a liquid layer


Macrocopic single crystal Graphene

V Babenko, N Grobert
Production of two-dimensional nanomaterial e.g. graphene used in electronic device, involves forming two-dimensional nanomaterial on liquid surface containing molten eutectic compound, of substrate by chemical vapour deposition. Millimetre-sized crystals of high-quality graphene can be made in minutes instead of hours using a new scalable technique, Oxford University researchers have demonstrated. In just 15 minutes the method can produce large graphene crystals around 2-3 millimetres in size that it would take up to 19 hours to produce using current chemical vapour deposition (CVD) techniques in which carbon in gas reacts with, for example, copper to form graphene.

Graphene manufacture technique


Graphene domains

N Grobert, AT Murdock, AA Koos
A commercial process for producing graphene and other 2D nanomaterials by chemical vapour deposition (CVD) using cheap copper foil. Producing two-dimensional nanomaterial (graphene) by chemical vapor deposition, used in e.g. display, comprises contacting substrate with flow of hydrogen and flow of precursor such that precursor forms material on surface of substrate

In situ quality control tool for use in extreme environments

SS Meysami, N Grobert
Device useful for transferring analyte, preferably nanomaterial from reaction chamber to detector for detecting analyte, comprises tubular component for receiving and communicating with sample, and jacket for regulating temperature.
The invention permits the monitoring of the chemical reaction in-situ, can reveal how the reaction is progressing in real time, and helps identify intermediates. Quality control of commercial scale nanomaterial production is vital to successfully exploiting the materials in future applications, for example as components in electronic devices, super-strong and lightweight composite materials, energy generation and biomedicine. An analytical device developed at Oxford will enable quality-assured nanomaterials to be made faster, cheaper and in commercial quantities, when used to control a manufacturing process within a range of reactors, such as those for chemical and physical vapour deposition (CVD & PVD). Mainstream industrial monitoring of production of analytes (gas, liquid, solid phases or mixtures) from drying, baking, and roasting ovens and refrigerators from -100 to 1500C is also possible when used with appropriate, commercially available instrument analysers.

Industrial scale production of aligned carbon nanotube/glass composite carpets.


Nanotube Carpet

RI Todd, N Grobert, G Otieno
Forming a composite material comprising nanotubes oriented in a matrix comprising a ceramic material, comprises providing an array of substantially aligned nanotubes, and providing a ceramic matrix material in the form of a solution
The invention involves a technique to modify the structural features of nanotubes, making them suitable for thermal interface materials for heat sinks, thermal/gas/electrical sensors, high performance brake pads and molecular filters. The Oxford invention uses well established and highly versatile low cost techniques with minimum modifications. It permits in-situ chemical functionalisation to tailor speciality nanocomposite materials for future technological applications. The resultant ceramic composite material is a strong uniform carpet able to transfer heat efficiently and rapidly via the aligned carbon nanotube (CNT) embedded in its structure. (read more)
