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.

Stretchy, but Smaller & Softer Than Expected; Berry Fragrance Dominates; May be Best 4 Puppies
I was directed to read guidelines that were on the internet, prior to use. I was not expecting that and that was a big turn-off. Basically, it's all about liability, this product has the possibility of being torn apart and I am basically warned that if a piece is chewed off, that's bigger than a grain of rice, to toss, this. I was repeatedly reminded, again and again, and again that pet safety was my responsibility. Yeah, I know that. All these suggestions and warnings should have been made clearer in the listing. Is this built to flex? Yes. Does it bend? Yes. Does it stretch? Yes. Is this rugged? That's open to debate, based on the users, for a puppy, to some degree, but their teeth are very sharp. Is this soft on teeth? I don't disagree. Does this have a durable design? Depends on the user. Floats in water? I do not doubt it. Does this have an enticing scent? For a human, yes, for a pet? Depends if your pet loves berries. This is no pigs ear/bone, so, chewing is not a natural draw that I saw, which I think may be better, because this is soft and easier to tear to pieces than expected. To motivate the first time, I found it best to initiate the tug of war, but this is smaller than I envisioned too, causing me to have to bend considerably to participate. A tennis ball in a tube sock is longer. A two-dog tug of war works best with this. Nevertheless, it's a better toy than teaching pooch to have a battle using clothing, avoiding future attractions to my socks. There is some flexibility to this. Durability is an issue. I think this would have been more interesting if it had been made out of rawhide. It does have a comfortable grip, for a human, but the toy pays a price for that with what I would consider fragility. The berry fragrance dominates, it's nice for a human, but sorry, it ain't no bacon aroma. It's like a thick heavy rubber hose. Value? In hindsight, I just do not see the value I was expecting. I mean really, a grain of rice warning not to use. Durability at issue in my eyes. Country of origin? Vietnam. Is this perfect? Not in my opinion. Rating? A strong three (3) stars at best in my eyes. This is not for a tough chewer. I have to constantly monitor its condition. It does succeed as a tug toy, but it has more limitations that I was expecting. I hope my thoughts added a bit of information.

Bully proof?!
Size: 5 in
We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later! They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!

When this chew arrived, it immediately became a favorite. It seems sturdy and is soft enough to be dental friendly.

My dogs finally chewed pieces off of these bones but it took forever for them to do it and they didn’t chew very much off! These are great and I will buy more!
