Product Overview

 

Graphene foam presents a three-dimensional network structure similar to foam. It is composed of numerous interconnected graphene layers, which interweave and construct rich pores. The size of pores varies from nanometer to micrometer, presenting a highly open and interconnected structure as a whole. The preparation of graphene foam film by CVD method is usually carried out at high temperature (usually several hundred degrees Celsius to over one thousand degrees Celsius) and specific atmosphere (such as carbon containing gas, etc.), where the carbon source gas is decomposed and carbon atoms are grown on the substrate to form graphene under the action of a catalyst. Then, by controlling the growth conditions and subsequent treatment, graphene can form a three-dimensional foam structure. For example, using copper foil as the substrate and methane as the carbon source gas, the reaction is carried out in a high-temperature furnace. Firstly, methane decomposes at high temperatures to produce carbon atoms, which deposit on the surface of copper foil and gradually form graphene layers. Then, by controlling parameters such as reaction time and gas flow rate, graphene sheets are interconnected and grow into three-dimensional foam structures. Finally, the graphene foam is transferred from the substrate to obtain an independent graphene foam material.

The graphene foam prepared by CVD method has the advantages of high quality and regular structure. The growth process of graphene can be precisely controlled to obtain graphene foam with specific morphology and properties.

Product Features

 

Excellent electrical properties: graphene foam has good conductivity, which makes it have potential application value in the field of electronic devices. It can be used as a conductive material for the preparation of flexible electrodes, supercapacitors, etc.

Excellent mechanical performance: Although graphene foam is a lightweight material, it has high strength and toughness. Its three-dimensional structure endows it with certain compressive and tensile resistance.

Good thermal performance: graphene foam has potential applications in the field of thermal management due to its high thermal conductivity. For example, it can be used as a heat dissipation material in electronic devices, effectively conducting the heat generated inside the device and preventing damage due to overheating

Efficient adsorption performance: due to its porous structure, graphene foam has good adsorption capacity for gas, liquid and other substances in theory. It can adsorb various organic pollutants, heavy metal ions, etc..


Application Fields

 

Supercapacitor: Graphene foam, as an electrode material, can achieve high capacitive performance and fast charge discharge rate by using its high specific surface area and good conductivity, providing efficient energy storage solutions for electronic equipment.

Battery electrode material: Its three-dimensional structure can provide a good channel for ion transport in the battery, improving the charging and discharging performance and cycle life of the battery. For example, in lithium ion batteries, graphene foam can be used as a carrier of negative electrode materials to improve the conductivity and structural stability of negative electrode materials.

Hydrogen storage materials: with its porous structure and good hydrogen adsorption performance, graphene foam has the potential to be an efficient hydrogen storage material, providing a new way for the storage and utilization of hydrogen energy.

Reliable Hub That Gets the Job Done
Color: Blue, Color: Blue
Solid Anker USB C hub that does what it’s supposed to do. Ports work well and it’s easy to use right out of the box. Only downside is the hard plastic casing, it feels fine, but I could see it cracking if something heavy drops on it.

Helped transfer data from Samsung Galaxy S21 with broken screen.
Color: Black
Helped me transfer data from a Samsung Galaxy S21 with broken screen. Simple put USB C end into phone , grab HDMI cable and plug into hub , then plug HDMI end into a monitor. Then grab a wireless keyboard & mouse and plug dongle into hub. Your phone will output to monitor and you can transfer data via Smart Switch using keyboard & mouse. Will only work if phone is unlocked I found on S21.

Anker 332 USB-C Hub (5-in-1): The Swiss Army Knife of Connectivity
Color: Black
Ever felt like your laptop was playing a cruel joke on you with its lack of ports? Enter the Anker 332 USB-C Hub (5-in-1)—the tech equivalent of a superhero swooping in to save the day (and your productivity). Port Party This hub is like the ultimate party host: it’s got a little something for everyone. Need to connect an external monitor? Boom, there’s a 4K HDMI port. Want to transfer files faster than a cheetah on a caffeine rush? It’s got two 5 Gbps USB-A ports and a 5 Gbps USB-C data port ready to go. Oh, and don’t worry about keeping your laptop charged while you’re multitasking like a boss—there’s a 100W PD-IN port to keep the power flowing. 4K HDMI: Because Why Settle for Less? Let’s talk about that HDMI port, shall we? We’re talking 4K at 30Hz, which means your Netflix binge or work presentation will look crisp, clean, and oh-so-satisfying. It’s like upgrading from VHS to Blu-ray—you won’t believe you ever survived without it. File Transfers in a Flash Remember the days when transferring files felt like waiting for dial-up internet to connect? Yeah, those days are over. With up to 5 Gbps transfer speeds, you can move files so fast that you’ll barely have time to grab your coffee before it’s done. Just think of all the time you’ll save—and how much more you can procrastinate as a result! Pass-Through Charging: Power Up, Don’t Power Down One of the worst feelings in the tech world is watching your battery icon turn red while you’re in the middle of something important. But fear not—this hub’s got you covered with up to 85W pass-through charging. So, go ahead and keep doing whatever it is you’re doing, whether it’s crushing deadlines or browsing cat memes (no judgment here). Compact and Reliable The Anker 332 USB-C Hub is compact enough to slip into your laptop bag without a second thought. And with an 18-month worry-free warranty, it’s clear that Anker has your back—just in case you get a little too enthusiastic with all those ports. Final Thought In a world where laptops keep losing ports faster than you lose socks in the laundry, the Anker 332 USB-C Hub is the perfect solution. It’s reliable, versatile, and just what you need to bring your laptop back to life. So go ahead—plug in, power up, and let the good times (and files) roll!

Excellent Product - USB C - power and data transfer!
Color: Black
It works great. I used this to connect two USB-C devices: one from the POS printer and another for charging, both connected to my tablet into one USB-C. It solved the biggest issue that I was facing.
