Nano silver powder, as an important functional material, plays an important role in multiple industrial fields due to its unique physical and chemical properties. Among them, 100nm silver powder (silver powder with a particle size of 100 nanometers) has become one of the most widely used specifications due to its excellent performance in conductivity, antibacterial and catalytic properties.
The application range of 100nm silver powder is quite extensive, covering almost all fields that require high-performance conductivity, antibacterial, and catalytic properties.
1: In the field of electronics and optoelectronics
1-1: Conductive paste and ink: 100nm silver powder is a key raw material for preparing photovoltaic silver paste, conductive ink, conductive adhesive, and conductive coating. Its high conductivity and suitable specific surface area (about 14 m ²/g) enable it to sinter at lower temperatures to form a highly conductive network, which is used for printed circuit boards (PCBs), flexible printed electrodes, radio frequency identification (RFID) antennas, and more.
1-2: Flexible electronic devices: In flexible displays, wearable devices, and flexible sensors, conductive films or adhesives with 100nm silver powder can provide excellent conductivity, flexibility, and anti-static effects.
1-3: Electromagnetic shielding: Silver powder can be used to prepare electromagnetic shielding materials, which are applied in electronic devices to prevent electromagnetic interference.
2) Antibacterial and Medical Fields
2-1: Antibacterial agent: 100nm silver powder has strong antibacterial properties. It can be used as an additive in antibacterial coatings, antibacterial fibers (such as textiles), antibacterial plastics (such as ABS, PC, PVC and other substrates), and medical dressings
It can effectively inhibit the growth of microorganisms such as Escherichia coli and Staphylococcus aureus.
2-2: Medical applications: Nano silver powder is widely used in gynecological medicine and other medical fields due to its ability to disperse and form silver ions, which have antibacterial effects.
3: In the field of new energy and environmental protection
3-1: Photovoltaic cells: 100nm silver powder is an important filler for manufacturing conductive silver paste for solar cell electrodes, which can improve the collection efficiency of electrodes and the photoelectric conversion efficiency of the cell.
3-2: Energy storage devices: Adding 100nm silver powder to the electrode materials of lithium-ion batteries and supercapacitors can serve as a conductive agent to improve the conductivity and electron transfer rate of the electrodes, enhance charge and discharge performance, and improve cycling stability.
3-3: Catalysis and Environmental Protection: 100nm silver powder can be used as a catalyst for organic synthesis, catalytic reactions in fuel cells, and photocatalytic wastewater treatment
Environmental protection fields such as exhaust gas purification (such as catalytic oxidation of VOCs).
4: Other industrial sectors
4-1: High performance composite materials: Adding 100nm silver powder to polymer plastics (such as PE, PP, etc.) can prepare composite materials with conductive, thermally conductive, or antibacterial functions.
4-2: Cultural relic protection and architecture: Nano silver powder can be used in cultural relic protection agents and architectural coatings to provide antibacterial protection.
