Dow Corning has a place in the fields of materials used in semiconductor manufacturing, such as dielectric materials and photosensitive resins. The company's recently introduced silicone photosensitive resin, which can be used for a new generation of 193 nm wavelengths, has also developed CVD dielectric materials for a new generation of semiconductors. In addition, Dow Corning found a way to reduce material consumption and silane coupling agent production costs, and developed a more economical method—the use of phase transfer catalysis to produce silanes in the silica treatment components needed for eco-friendly tires. , thereby reducing the cost of environmental protection tires, providing a feasible solution for the universal use of environmentally safe and environmentally friendly tires.
Rohm and Haas Company of the United States is committed to providing global customers with advanced new materials for semiconductors, optoelectronic products and industrial applications. Its markets include wafers, chips, optoelectronics, plastic plating, decorative precious metal plating and anti-corrosion, liquid crystal displays, etc. Multiple areas. The company's use of innovative technology produced 248nm and 193nm photoresist, anti-reflective coating, to meet the 300mm manufacturing requirements of the copper slurry and polishing pads, etc., fully demonstrated the advantages of Rohm and Haas in the field of new materials.
GE Global Research has developed a flexible organic light-emitting diode (OLED) substrate that has been developed from a high-temperature polycarbonate (PC) and a transparent, ultra-high barrier organic-inorganic coating. The coating can make the OLED device resistant to oxygen and moisture. This achievement uses a plastic substrate instead of glass to achieve a low-cost, lightweight, flexible organic display. This development will open the door for new applications such as portable, durable and rollable displays.
The United States Merck Chemicals Chilworth Technology Center has successfully developed a new type of polymer that is comparable to amorphous silicon in terms of its electrical conductivity. This polymer material is a polythiophene semiconductor that can replace amorphous silicon for the production of ultra-thin transistor substrates in screens and displays.
In addition, NEC Corporation of Japan developed an ultra-thin rechargeable flexible polymer battery with a recharge time of 30 seconds; PlasticLogic, a British plastics electronics developer, developed a flexible organic substrate display with a resolution of 100ppi; a generic display company Developed Phosphorescent Organic Light Emitting Diode (PHOLED) materials in cooperation with Mitsubishi Chemical Corporation. The total cost of OLEDs is 30% lower than that of liquid crystal displays (LCDs). A team of German scientists developed shape memory polymers that can be deformed by magnetic fields. .
Many new plastic materials and their new applications that cannot be replaced with conventional materials stand out from the crowd. Diolen Industrial Fibers of the Netherlands has become the first company in the world to develop high-tenacity polyfilament yarn based on polyphenylene sulfide (PPS) and bring this product to market. PPS is a highly functional polymer that combines high toughness with excellent chemical resistance, temperature resistance and fire resistance, and is suitable for high-end applications in harsh environments.
New types of biodegradable polymer composites are increasingly used. Cellphones commercially available in Japan have been made of shells made from grain-derived polymer composites. The Foé„„ma N701Ieco mobile phone's case replaces plastic made of petroleum with kenaf-reinforced polylactic acid (PLA) resin. This enclosure was jointly developed by NEC Electronics and the textile/plastic group Unitika. It is alleged that about 90% of the phone casing can be made from biomass.
New nanomaterials have also been continuously developed and utilized. For example, South Korea's LG Chemical Co., Ltd. has successfully developed high-impedance engineering plastic (EP) using nanotechnology, and has been applied to food, cosmetics, pesticides, and automotive fuel tanks. BASF launched Ultradur HighSpeed ​​nano-polymer modified polybutylene terephthalate (PBT), which has been used for the first time in commercial production of telephone line sockets.
The development of new chemical materials springs up to the forefront of multinational chemical companies
With the rapid development of science and technology in the world today, new materials for chemical industry are even more results. The development and adoption of new chemical materials will not only provide opportunities for transnational corporations to achieve sustainable development and increase efficiency, but also add a beautiful new landscape to the rich and colorful world. Dow Corning Corporation has always been a leader in the silicone market. Continuous innovation in the field of new materials is the essence of the company's development.
