Product Overview

 

The particle size of nano silver powder is usually between 1-100 nanometers. Compared with macroscopic silver particles, the particle size of nano silver powder is extremely small, which gives it unique physical and chemical properties. For example, when the particle size of silver particles decreases to the nanometer level, the proportion of surface atoms increases significantly, and the surface effect is significantly enhanced.

The particle size also affects the color of the nano silver powder. Generally speaking, as the particle size decreases, the color of nano silver powder gradually changes from silver white to yellow or even brown, due to the surface plasmon resonance effect of the nanoparticles. The absorption and scattering characteristics of silver nanoparticles with different particle sizes in the visible light region are different, resulting in different colors. Silver is an excellent conductive material, and due to its nanoscale effect, silver nanoparticles also have some special electrical properties while maintaining the good conductivity of silver. For example, the resistance of nano silver powder increases with the decrease of particle size, because the reduction of nanoparticle size leads to a decrease in the average free path of electrons, and the transmission of electrons in nano silver powder is subject to more scattering and obstruction.

Nano silver powder may exhibit quantum phenomena such as quantum tunneling at low temperatures. When the distance between silver nanoparticles is small enough, electrons can be transmitted between particles through quantum tunneling effect, which makes silver nanoparticles have potential application value in some nanoelectronic devices, such as preparing conductive connections and quantum dot contacts in nanocircuits. Nano silver powder has unique optical properties, mainly due to its surface plasmon resonance effect. When the frequency of incident light matches the oscillation frequency of free electrons on the surface of nano silver powder, strong absorption and scattering phenomena occur. This surface plasmon resonance effect endows nano silver powder with strong optical absorption and scattering capabilities in the visible and near-infrared light regions.

Product Features

Excellent conductivity: Nano silver powder has excellent conductivity and is an important material in the field of microelectronics.

Excellent antibacterial performance: Nano silver powder has strong inhibitory and killing effects on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, and does not develop drug resistance. Its antibacterial performance is directly related to its particle size, and theoretically, the smaller the particle size, the stronger the bactericidal performance.

Excellent thermal conductivity: Nano silver powder also exhibits excellent thermal conductivity and can be used to prepare thermal interface materials to improve thermal conductivity efficiency.


Application Fields

 

High end silver paste: In the field of electronic technology, nano silver powder is widely used in the preparation of high-end silver paste, providing efficient conductive function for electronic devices

Conductive coating: Nano silver powder can be used to prepare conductive coatings, which theoretically can be applied in fields such as transparent conductive electrodes, anti-static coatings, electromagnetic shielding, etc.

Medical field: In the medical field, nano silver powder can theoretically be applied to medical devices, wound dressings, disinfectants and other products due to its excellent antibacterial properties, effectively inhibiting bacterial growth and reducing the risk of infection

Other fields: In addition, nano silver powder can also be used in various fields such as catalytic materials, new energy, electroplating industry, as well as green household appliances and home products

Works fairly well! Smells good.
Scent: Sweet Peach & Nectar
This works really good, it has a sweet peach smell to it and lasts for most of the day. After a long day the sweat makes it smell odd to me as my partner doesn't notice a change. Ive only used it after my showers since im afraid it might change the smell if I reapply throughout the day. When i get a new one i will try that and update if it makes me smell decent still after a few uses or if it starts to stink. It hasn't caused any irritation to my skin. I do like how easy it is to roll both ways and it doesn't get stuck like most deodorants I've used. Though I dont like how it visibly sticks to my clothes as it takes a bit to dry.

LOVE it! Easy to use, pigment is perfect, lasts all day!
Color: Black Brown, Size: 0.01 Ounce (Pack of 2)
I am a victim of early childhood bullying by my brother, who used me for the butt of all his jokes. My eyebrows for one. Always saying they were so think, I looked like the character from the guy from the Muppets Bert or Ernie. Always pointing them out and ridiculing me in front of everyone. I was little and it got worse as I got older, so when I was in grade school, I got tired of it and got ahold of my older sister's Nair hair removal and took them off. Imagine being in fifth grade fat, ugly and no brows, the taunting got even worse, so I had to learn from a young age to draw them in, I went through hell! Throughout the years, I learned how to draw them in and always used Jordana pencils as they were cheap and perfect. Since they no longer make them anyone, I went on the hunt for a better pencil, and after spending tons of money on eyebrow pencils and seeing how worthless they were, I tried these and OMG, FINALLY, someone got it right. These pencils are perfect, it's a self sharpening mechanical pencil so you don't loose half the pencil when trying to sharpen, It applies perfectly, the coverage is perfect, stays on forever, and removes with ease. One other thing that makes this pencil even more dynamic is the eraser at the end of the pencil, it allows you to shape your brows perfectly!

Sharp lines that don’t smudge
Color: Black, Size: 0.01 Ounce (Pack of 2)
This eyeliner is very precise and easy to apply, allowing you to create clean, sharp lines without much effort. The waterproof formula holds up well throughout the day without smudging or fading easily. It works well for both subtle everyday looks and more dramatic winged eyeliner styles. The built-in sharpener also helps maintain precision over time. Overall, it’s a dependable eyeliner for long-lasting eye definition.

Revlon colorstay pencil
Color: Sapphire, Size: 0.01 Ounce (Pack of 1)
This liner goes on well and has staying power. I like the color and am happy with this purchase, however… it needs to be sharpened just about every use. I probably won’t order again.
