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

Spacious, organized, and perfect for travel!
Size: Large, Color: Black
This travel laptop backpack is absolutely fantastic! It's spacious and well-organized with multiple compartments for everything you need. It's airplane carry-on approved and fits perfectly in the overhead bin. The laptop compartment holds up to a 17" laptop securely with great padding. The water-resistant material keeps everything protected and the straps are comfortable for long trips. Great quality for the price. Highly recommend!

Good bag for a good price
Size: Large, Color: Amourpink
Really loved this backpack. I got it after reading all the reviews and wanting something for travel. The inside pockets with extra compartments that are water proof or organizing was a really nice touch. I traveled on airlines with this a few times and then started using it for school as well. It help up really well. I tend to be kind of rough on things and unfortunately the zipper broke. I'm unsure of if I over stuffed it or it was just a cheaper zipper. I would have considered resorting it because I used and loved it so much but my mom's dog got to it and it was not salvageable after that. I would recommend this specifically as a great travel backpack for the air port but it can easily double as an over night bag or school back pack.

So big, but lightweight!
Size: Large, Color: Amourpink
I bought this backpack to have as my "personal item" on the many flights I have to take. It is the perfect weight, having a place for just about anything you'd want to have during a flight, as well as having your carry-on items. The charging port is a bit of a challenge to plug in because of how you have to position the cord, but it is doable. I did not end up using the charging feature on my most recent flight, but I can see how it would be helpful for the travel that does not provide many charging stations. I have some serious back issues, but even full, I found this backpack to be a reasonable weight. I cannot attest to it's durability at this time, as I've only taken it on two trips now, but it is a great bag. There are many compartments, which can be good and bad. I recently put my wallet with all my identification and cards in a compartment that was easily missed. I thought I had lost my wallet and was panicked about how I'd get on my return flight if I didn't find it. After completely emptying the bag in my friend's car, and running my hands all over the compartments, I found the wallet. Here's the thing, my wallet is not little, so you can see that the walls of this backpack are pretty thick. The pink color is more of a dusty pink, which I find to be more attractive than a bright pink for something like this.

Durable and easy to carry
Size: Large, Color: Amourpink, Size: Large, Color: Amourpink
I absolutely love this backpack! I got it for our two weeks long Northern Europe trip. It is very lightweight, spacious, and surprisingly comfortable even when fully packed. The compartments are well designed and make it easy to organize everything for travel. I especially liked how convenient it was for airport trips and fitting over the carryon’s handle and under the airplane seat. The material feels durable and the overall quality exceeded my expectations for the price. Stylish, practical, and perfect for short trips or everyday use. Highly recommend!

Very good product
Model: iPad Mini 6/A17 Pro 7th Gen
Nicely attaches to the iPan. Easy and no bubbles. had one and worked it completely out. Had all the need items for the installations. Screen touch works, cover went on without a hitch.
