Why Graphene Oxide?
▪ William Blythe runs an extensive R&D programme focussing on advanced materials
▪ Graphene oxide has the potential to impact multiple sectors through several functionalities
▪ Manufacture fits with William Blythe’s core capabilities
▪ Experts in redox chemistry
▪ Expertise in controlling and measuring the physical properties of products
▪ Well developed Process Safety Management System to allow the safe scale up of hazardous
processes and a top tier COMAH site allows use of hazardous chemicals
Graphene Oxide at William Blythe
▪ Development programme began in 2015, focussing on the Hummers synthesis
▪ Optimisation of process has led to a scalable method for manufacturing graphene oxide from graphite,
tuned for dispersability
GOgraphene
▪ Online webshop launched in August 2016
▪ Designed to supply researchers (academic and industrial)
with graphene oxide products
▪ Researchers have confidence in consistent supply for
their work
▪ Purchase avoids hazardous synthesis
▪ Products currently available:
▪ Freeze dried powder
▪ Flake
▪ 1% aqueous dispersion

Is it realistic to expect the same grade of material to
be appropriate in all potential applications?
▪ Both the physical and chemical properties could
impact the material compatibility and
performance
▪ William Blythe is developing capabilities to tune
graphene oxide for the application is will be used
in
▪ Working together with customers, William Blythe
will develop application specific grades of
graphene oxide
Chemical Optimisation
What? Control of C / O ratio
Why? Affects how different material is to graphene
Oxygen Content
What? Control over the oxygen functional groups present
Why? Impacts the electronic properties when reduced
Oxygen
Functionality
What? Addition of non-oxygen functional groups
Why? Can lead to different material properties
Surface
functionalisation
William Blythe is working to develop a suite of capabilities to optimise the control of
the chemical characteristics of their graphene oxide according to customer
requirements
Physical Property Optimisation
By developing capabilities to control the physical properties of graphene oxide,
William Blythe will be able to optimise their graphene oxide according to customer
requirements
What? Control of sheet size distribution
Why? Impact on performance and compatibilization
Lateral Sheet
Dimensions
What? Optimization of the density of solids
Why? Can impact on handling procedures
Bulk Density
What? Control of material content in dispersions
Why? Some applications require low energy inputs to achieve

Impacts the electronic properties when reduced Oxygen Functionality What? Addition of non-oxygen functional groups Why? Can lead to different material properties Surface functionalisation William Blythe is working to develop a suite of capabilities to optimise the control of the chemical characteristics of their graphene oxide according to customer requirements
  • 11. Physical Property Optimisation By developing capabilities to control the physical properties of graphene oxide, William Blythe will be able to optimise their graphene oxide according to customer requirements What? Control of sheet size distribution Why? Impact on performance and compatibilization Lateral Sheet Dimensions What? Optimization of the density of solids Why? Can impact on handling procedures Bulk Density What? Control of material content in dispersions Why? Some applications require low energy inputs to achieve full dispersion Dispersion Concentration
