LINTEC Integrated Report 2021
47/116

At the Nano-Science & Technology Center, our R&D base in the U.S., we are concentrating efforts on the establishment of technologies for creating carbon nanotube sheets. Carbon nanotubes are cylindri-cal materials made from carbon with diameters of one-billionth of a meter (a nanometer). They excel in strength despite being light-weight, and feature high conductive properties for electricity and heat. The Center is developing technologies for processing carbon nanotubes into sheets and yarn. We aim to develop markets for these forms of nanotubes in various sensor applications. Moreover, we are developing and commercializing anti-dust covers for photo-masks (original plates of circuits), which are called pellicles, for EUV lithography systems that are able to form fine circuits on semicon-ductor wafers. LINTEC has been developing special sheet materials that use heat. For film heaters that generate heat with electricity, we propose materials that prevent the accretion of snow and ice on signal equip-ment and signs, for example, as well as on the sensors of automo-biles and communications equipment, by applying its proprietary wiring and sheet technologies to make highly transparent and curve-following properties a reality. The amount of heat generated by electronic devices has increased with the higher speed and capacity of data transmission in 5G technology. We are therefore developing ultra-thin and lightweight cooling sheets that take advantage of the Peltier effect to absorb and release heat through electrical currents. We are also developing ultra-thin thermoelectric sheets that can convert waste heat from plants into electrical energy. As a part of its initiative to develop recycling-oriented products, LINTEC has developed high-frequency dielectric heating adhesive film that is able to adhere different types of materials together, such as stainless steel and plastic, by melting when exposed to high-frequency waves. It has the same adhesive strength as traditional liquid adhesives, but can be applied in a shorter amount of time, and when exposed again to high-frequency waves, the joined materials can be separated for easier recycling. VOC emissions are also reduced. We aim to develop this adhesive for a wide range of appli-cations, including automobiles, construction materials, and apparel. adhesiveness is sharply reduced when electricity is run through the sheets, are well suited for applications that entail joining together parts and materials used in electrical devices and automobiles. We believe these sheets will make it easier to recycle and reuse metallic and plastic parts.In addition, our electrical release adhesive sheets, where the Carbon nanotubeFilm heaters with possible applica-tions in automotive sensorsHigh-frequency dielectric heating adhesive filmUsing high frequencies to melt adhesive film for adhering different materialsAdhesive sheet that can be easily removed by passing electricity through itCarbon nanotubes in yarn form are woven into a globe and used as a sensorUltra-thin and lightweight cooling sheets for effective heat control of 5G-compatible electronic devicesHigh-frequency dielectric heating adhesive filmAdherendLINTEC Integrated Report 2021High frequencies + application of pressure45Carbon Nanotube Products Made with Distinctive TechnologiesSheet Materials That Use Thermal PropertiesSpecial Adhesive Sheets for Recycling and Reuse
