2010 Nobel Prize in Physics

Andre Geim (left) and Kostantin Novoselov (right) of the University of Manchester shared the 2010 Nobel Prize in Physics for their groundbreaking work on graphene just 6 years

earlier.

What is Graphene? An Allotrope of Carbon

Diamond Graphite

1980sC60 “Buckyballs”

1990sCarbon Nanotubes

2000sGraphene

Graphite is simply many stacked layers of

graphene.

What is Graphene?

• Strongest material known• 5x more than steel

• But stretchable & flexible

• And very thin & transparent• Just 1 atom thick (0.34nm)

• High electrical conductivity• Much higher than silicon

• High thermal conductivity

• Excellent gas barrier• Even helium can’t pass

Graphene is two dimensional (2D) carbon, and it displays many unique and interesting properties. It’s often called a “wonder material.”

Example Application: Smart Glass

Smart glass can be electrically controlled to switch between an on/off state. In the off state, the window becomes opaque adding privacy and blocking heat.

o Total Solid Content (%TSC) and Dry Rubber Content (%DRC) The result of total solid content and dry rubber content of the sample are

shown in table 3 and figure 7. The average values of TSC and DRC were 25.3±0.3 and 23.7±0.5 % respectively. It was found that TSC obtained was higher than DRC by about ̴ 2% due to the presence of non-rubber constituents.

Figure 10 Surface resistivity of rubber composite films when increase graphene content

Conclusion

This interim report the method for preparing dipped rubber films from Neoprene latex that is reinforced by Functionalized Graphene Nanoplatelets (GNPs) and Electrolytic Exfoliated Graphene (FLG). The preparation was divided into two steps. Firstly the FLG was synthetized from graphite rod by using electrolytic exfoliation method in PSS solution. Secondly, GNP-Ar, GNP-O2, GNP-COOH, GNP-NH3, FLG and vulcanizing chemicals were mixed with Neoprene latex. The latex compound was formed into thin film by dipping process and followed by curing step.

Swelling studies of the composite films in toluene revealed that the degree of swelling decreased with increasing graphene content. In addition the degree of swelling tends to decrease while using GNP-NH3, GNP-O, and GNP-COOH respectively.

The results of mechanical properties indicated that GNPs, and FLG particles exhibited the reinforcement effect on NR films. And the tensile strength and elongation at break increased with increasing at low contents of functionalized graphene (GNPs) and Electrolytic exfoliated graphene (FLG) and slightly decreasing at high content of graphene. The optimum composition of composite film is 2.0%wt of GNP-COOH adding that show increasing in modulus, tensile strength, and elongation at break ̴ 2 times of neat NR film.

Electrically conductivity properties of the composite films were examined using Electrometer. The presence of Graphene in the NR matrix could observe a decrease of surface resistivity. When Graphene loading was increased to 4.0%wt, the surface resistivity of the nanocomposite was sharply decreased to 106 Ohm/square which could be designated as a static dissipative nanocomposite.

• Replacement of silver inks in some applications• Conductive silver inks cost ~$1,000 - $1,500/kg• Conductive carbon inks are ~$100 - $200/kg• By enhancing carbon inks with graphene, we can make

an ink that is “conductive enough” for some applications

• Allows a low cost alternative to silver inks• Production & setup costs can also be reduced – only

one print pass (enhanced carbon ink) instead of two (carbon and silver inks)

Summary• We know from experience that when we add graphene to just about any

target material we can see enhancement of mechanical, electrical, thermal and barrier properties.

• Haydale’s plasma process can aid in the dispersion of graphene into many different materials.

• Graphene can enhance the conductivity of carbon-based inks, potentially enabling a replacement for more expensive silver inks.

• Target applications for Haydale include blood glucose sensors and pressure sensors (strain gauges), but our inks are suitable for any application where large amounts of silver ink are currently consumed.
