Nano paper electronic products are more environmentally friendly
portable, low-cost, flexible, green and environmental protection, which are important development trends of current electronic products. All kinds of nano paper developed by European and American countries make people look forward to the future electronic products. The nano paper transistor jointly developed by Tongji University and the University of Maryland in the United States recently takes nano paper as the substrate, which is fully transparent, flexible and degradable, and has taken an important step towards paper electronic products
nano paper generally refers to paper made of nano materials or improved by nano technology. In addition to its application properties such as writable and reproducible, it also has excellent properties such as super hydrophobic, self-cleaning, moisture-proof, aging resistance and high printing surface strength. It has a relatively broad market application prospect
ordinary transistors generally use inorganic semiconductor materials, such as crystalline silicon, which is hard and easy to break. The transparent and flexible organic semiconductors are selected as the nano paper transistors, and the same transparent and flexible nano paper and carbon nanotubes are used as the substrate materials and electrodes respectively. Finally, the overall flexible, transparent, environmentally friendly and degradable nano paper transistors are formed. The actual performance test shows that the overall transparency of the nano transistor is as high as 84%. Even when the whole device is bent and rolled into a thin cylinder, the transparent transistor on it can still maintain excellent working performance
the biggest feature of nano paper transistors is that they integrate transparent, flexible and degradable functions and characteristics into one device at the same time. If electronic products are made on plastic substrate materials, although they can be bent and transparent, they cannot be degraded, and eventually a large amount of electronic waste will be produced, polluting the environment. Electronic waste has now become a major problem facing the world. Using degradable paper as the substrate material instead of plastic makes the device have the advantages of green and environmental protection
due to the thick fiber, opaque, rough surface and uneven surface of ordinary paper, it is not only difficult to form a complete, continuous and uniform high-quality semiconductor layer on it, but also easy to cause transistor leakage. Related technologies and preparation processes face many difficulties. 1 Sample. In contrast, nano paper is an ideal material. The preparation process of this transparent and smooth special paper is not very complicated. The specific method is to specially treat the wood pulp fiber used in ordinary papermaking to make its fiber size reach the nanometer level, which is far smaller than the wavelength of visible light. The nano paper produced in this way can effectively reduce the absorption and scattering of light, and not only become transparent, but also its surface is as smooth as plastic, which lays an important foundation for the next preparation of transistor circuits with excellent performance on it
combining the solubility of some organic semiconductor materials with the printability of paper substrate materials makes it possible to prepare electronic devices by full printing. PP belt tension tester is a testing instrument for testing thin film materials, and data display is possible. In this way, not only the cost of electronic products can be further reduced, perhaps, in the near future, people can also use renewable resources to print transparent and flexible electronic devices, that is, paper electronic products such as magic newspapers in the movie Harry Potter, or flexible, foldable and fully transparent displays in science fiction movies. In theory, nano paper transistors have taken a key first step towards environmentally friendly paper electronic products
