In recent years, flexible electronic devices and wearable electronic devices have been favored due to their excellent performance, ability to adapt to physical deformation, and ease of use, etc. However, conventional electronic devices are difficult to meet the requirements of flexibility and work in harsh environments. Electronic For example, metals are the preferred choice for conductive materials, but metals are susceptible to oxidation and corrosion, degrading performance and causing malfunctions; contaminants, moisture, rain, freezing and snowfall also affect the performance of electronic devices Of the performance; In the flood, heat or fire damage to electronic devices.So, can work in harsh environments all-weather-type flexible electronic devices aroused people's interest.
Recently, the research team led by Zhu Yingjie, a researcher at Shanghai Institute of Ceramics, Chinese Academy of Sciences, based on the research work of hydroxyapatite long nanowire refractory paper, uses hydroxyapatite long nanowires as the main raw material and carries the conductive Carbon black, and then polydimethylsiloxane coating treatment, developed a new type of hydroxyapatite long nanowire-based flexible waterproof conductive fire-resistant paper, integrated waterproof, conductive, electric, fire retardant and other functions , Can work in all kinds of harsh environments such as strong acid, alkali, high humidity, high temperature, underwater, snow and ice weather stable work.Hydroxyapatite long nanowires and conductive carbon black to build multi-level rough structure, polydimethyl Silicone coats provide a synergistic combination of hydrophobicity, multi-level roughness, and hydrophobicity to make super-hydrophobic surfaces flexible and conductive, with water repellency, self-cleaning and high thermal stability, and to withstand harsh environments More importantly, even though the new flexible waterproof conductive paper is soaked in water that it can work stably, the connected small lamps can shine continuously.In addition, the new flexible conductive paper has the effect of electrothermal , The power can be quickly heated in a short period of time, is expected to be applied to efficient and rapid deicing. The new flexible waterproof conductive fire-resistant paper has excellent high temperature and fire resistance, even in the fire burning can also work stably, the connection of small lights Continue to shine.With a variety of excellent performance, the new flexible waterproof conductive paper has good prospects in high-performance flexible electronic devices and wearable electronic devices.Related research results published in ACS Applied Materials & Interfaces, and apply for a Patent.
