An upsurge in Graphene research reveals an intensifying global contest to lead an impending industrial revolution. The wonder material – defined as being far stronger than diamond, more conductive than copper and as flexible as rubber .
Graphene is now at the heart of a worldwide contest to exploit its properties and improve methods to commercialize it.
Here is a list of Top 5 Game Changer ‘Graphene Patents’ that may perhaps, change the world around us.
Graphene-based heat sink for lithium batteries US patent application no (2013/0136966). A breakthrough patent application filed by Apple inventor Ramesh Bhardwaj of Fremont California. Graphene is 10 times better at conducting heat than graphite.
In order to adequately cool a polypropylene battery, a 30 Micrometer thick graphene coating can be used in a battery casing. He says the heat sink can occupy a small fraction of the space of the graphite version for the same enclosure – allowing for a bigger, longer-lasting battery to be installed.
In another battery patent application filed this week, Apple presented more clues that it is working on a wristwatch-shaped device, as CEO Tim Cook hinted last week.
A Unique LCD Matrix In recent times LCD screens have become a commonest part of our lives. They have gradually replaced the good old cathode-ray tubes in TVs and computers. Eventually the screens as they grow larger, the flatness of the layers becomes all the more important.
The root of the problem is unruly glued middle layers of the LCD Matrix that result, in obfuscating the LCD screen. Chinese Star Optoelectronics Technology Co Ltd (CSOT) resolves to solve this phenomenon by using, special conductive glue, filled with graphene or carbon nanotubes to make it conductive.
The conductive glue would be less than 7 micrometers in thickness, which result in a haze free LCD screen, through its first ever Graphene Patent application number 20130077030.
Samsung Antiglare Touch Screens. Samsung continues with its dominance in Patenting Graphene applications with its revolutionary US patent Number 8390589. To protect the use of graphene networks in capacitive touch screens.
With the use of nanostructures as the conductive layer of a touch screen, Graphene and its other nanostructures are already being explored as inexpensive substitutes for the expensive indium tin oxide (ITO) which is brittle.
It has an added advantage of being flexible and stretchable too as its touch screens counterparts. However this will most certainly place Samsung at a significant advantage to its peers in providing inexpensive transparent antiglare touchscreens.
IBM’s Modern Solar Cells Approved US patent number 8293607, defines a method to decrease electrical resistance in graphene solar cells, for use as a transparent electrode, on solar cells that extract electricity generated by sunlight.
As of now Indium tin oxide (ITO) is the material of choice for modern solar cells; ITO is brittle, making it inappropriate for flexible solar cells. Enter graphene, an excellent conductor with a high transparency, which in addition, is highly flexible.
In its natural form, graphene has a low electrical resistance compared to most other materials, making it an ideal choice for moving around electricity.
This is one of the many creative patents by IBM that use graphene for advanced electronics; this makes IBM an excellent choice for the graphene investor.
Bayer’s Patents for obtaining graphene from graphite by chemical means. German chemical company Bayer known in the pharmaceutical industry for its unsurpassed research capabilities, has joined the race by filing a U S Patent Application Number 20120256121 for obtaining graphene from graphite by chemical means.
Products made through this patented technique can be used in electrical capacitors, batteries, paints, and other catalysts or coatings. Bayer is a leading manufacturer of carbon nanotubes, but seems to be moving into graphene sales as well.
Bayer is listed under the symbol BAYZF on NASDAQ.
