An electronic component made of tantalum is placed on a support layer made of nanocellulose. The raw material of this cellulose is wood. On the morning of July 15th, Beijing time, researchers at the University of Wisconsin invented a biodegradable chip made of materials extracted from wood, and its performance is the same as that used in the radio communications industry. Researchers said that this new chip will help solve the increasingly serious problem of electronic waste pollution, some of which also contain toxic substances. They extracted a transparent material called wood cellulose paper from wood that could replace plastics and become a carrier for flexible electronic components. In the traditional chip manufacturing industry, transistors and other electronic components are fabricated on hard wafer surfaces. These wafers are made of semiconductor materials such as silicon. While the professor of electrical and computer engineering at the University of Wisconsin, Zhenqiang Ma, also used similar methods to make electronic components, he used a rubber stamp to remove the electronic components from the wafer and transfer them to a nanofiber. Made on a new carrier. This reduces the amount of semiconductor material used up to 1/5000, without sacrificing performance. In the two recent verification tests, Ma Zhenqiang and his colleagues demonstrated that they can use nanocellulose as a supporting layer for RF circuits, and the performance is similar to the RF circuits commonly used in smartphones and tablets. They also show that common bacteria can degrade these chips. Most of the semiconductor materials used in today's chips are used to make the support layer, and only a small part of the truly functional electronic components. Ma Zhenqiang said that this is a huge waste, and it will lead to serious pollution of abandoned electronic equipment. Nanocellulose can be produced by decomposing wood fibers to nanoscale. In recent years, researchers have demonstrated that this material can be a viable support material for a variety of electronic devices, including solar cells. However, these experiments by Ma Zhenqiang were the first to prove that the characteristics of this material make it possible to use it for efficient, high-performance RF circuits. Ma Zhenqiang said that the chip is ready for commercialization. John Rogers, a professor of materials science at the University of Illinois at Urbana-Champaign, also said that Ma Zhenqiang and his colleagues have used technology to become more mature in the electronics industry. Rogers developed a method for Ma Zhenqiang's team to help them transfer small amounts of semiconductor material from large wafers to nanocellulose carriers. Rogers said that the military is very interested in such electronic products that can be quickly decomposed, because it can avoid sensitive electronic devices falling into the hands of the enemy. However, the most important significance of this research is still in the field of environmental protection: all types of wireless communications equipment are rapidly increasing, and there is no sign of slowing down. People are also speeding up their equipment upgrades, often discarding outdated products. How to deal with the pollution generated by discarded electronic devices has become a serious problem that people have to face.
