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

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.
