Graphene is an incredible material

The future of Graphene is incredible.

Nick Bilton, the author of the New York Times today, issued a paper describing the future vision of graphene. The world’s toughest material can also be transparent, conductive, deformable, and waterproof at the same time. Nick Bilton cited a large number of academic papers in the article that this material will be disruptive to current electronic devices. influences.

Earlier there was even rumors that graphene was used in the solar cells of Apple’s new iOS device. Just a few days ago, Samsung also announced that they have been able to create transistors containing graphene materials, which will allow them to further manufacture "flexible display devices, wearable devices and other next-generation electronic products."

Graphene was discovered in 2004, but in recent years, with the concept of wearable devices, flexible screens, solar charging, and other concepts of heat, spotlights have hit the material again. What can you do with graphene? There are at least a few directions that can be determined: making electronic devices lighter, faster, replacing silicon with cheaper prices, significantly improving battery life, and even sounding like fantasy underwater charging.

In 2011, Northwestern University used graphene and silicon to create a new type of battery. It is said that the battery using this kind of battery can last up to 1 week, and it only takes 15 minutes for each charge. The American Chemical Society even said in 2012 that graphene-made screens can be as thin and portable as paper.

In addition to the aforementioned Samsung, IBM, Nokia, and SanDisk are also experimenting with graphene materials for the next generation of sensors, crystal conduits, and storage materials.

Berkeley University had made a graphene headset in 2013. In the same or better sound quality than Sennheiser headphones, graphene headphones are smaller and cheaper. In the previous article, more fantasy underwater conductivity, graphene can also be achieved, and does not require the same as other materials like oxide coating. The Bill Gates Foundation last year invested money in the study of graphene-containing condoms. It is reported that it can produce a new generation of products that are lighter, thinner, and will not seep through.

The future of graphene in the application of electronic products is likely to be integrated in our original physiological system. Prof. Aravind Vijayaraghavan of the University of Manchester said that in the future, graphene materials may be used in devices that can be transplanted into the human body to read human physical data or to treat them.

But there are also people in the industry who think this is just a game of speculating on the future. Because the extraction cost of graphene is still too high. Moreover, due to the existing methods such as redox, chemical vapor deposition and the like, it is difficult to balance the cost and the conductive efficiency of the finished product, and graphene preparation has not yet been industrialized. Therefore, it may take up to 10 years before it is used on a large scale in commercial products.
