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.

Bland and generic.
Format: Paperback
Very bland and generic. The art was serviceable but I quickly forgot everything within a day. Nothing memorable at all. I expect more from the head Batman writer. This seemed lazy. Ending was but a whimper.

A Nice Standalone JL Story
Format: Paperback
Justice League: Last Ride really isn't bad, but it never shines greatness either. Superman is suffering throughout this story from the loss of a friend and ally, as well as fatigue from constantly saving people. This is the crux of so many modern Hero stories. Instead of Superman being a beacon of hope, he is dealing with personal and emotional problems. Of course we all need to do just that, however, we as readers look to comics to inspire us. Superhero stories are far less uplifting today, instead bringing characters like Superman down to a more average level. While the story has a positive ending, it comes after six issues of these characters working through their grief. In some aspects I can appreciate it, but I also don't want to stew in depression. I used to look to comics to find stories of heroes working through adversity, and relating their unrealistic situations to how I could overcome my own. Lately, the idea of metaphor seems to be dead. What I really enjoyed: Chip Zdarsky actually gave the characters individual voices. That's one up on many books being published today. It was nice to see a fairly classic Justice League lineup in action. Some of the more recent membership has been odd choices. The art from Miguel Mendonca was fantastic. I'd love to see more of his stuff. There are some great story beats and the 1st chapter is pretty compelling. What could have been better: The dad jokes sprinkled throughout the story were pretty cringey. I'm still trying to understand if Batman and Superman quipping about the pronunciation of S'Mores was supposed to be funny. The story never had a sense of dire consequences, though I'm not sure that's really a bad thing. I think a few small changes to the tone, such as Superman or Wonder Woman being more of a voice of confidence and reason would have helped. We need that beacon of hope in stories like this. Overall: Story: 6/10. A fun read, but a bit of a depressing tone. Art: 8/10. Fantastic character art. I think Miguel Mendonca will be a 9/10 artist in the coming years. Value: 7/10. Definitely worth a read and at a great price currently ($11.99 as of 10/24/22)

A Spectacle!!
Format: Kindle
Aaron packed a LOT of Story, Political Commentary and exposition into one issue. This is a testament to what good Science Fiction and good Comics have the ability to become.

great opening to a unique twist
Format: Kindle
Different, in a good way. This unique twist is relevant and refreshing, and provides a fresh take on the man of steel.

A good start to a new Superman story
Format: Kindle
From this first issue, I like that Superman’s origin story is different from what we know. Although Kal’s parents are of the lower class, JorEl is still the one who seems to know about Krypton’s impending doom. It caught me off guard that Lois isn’t a reporter but part of this Lazarus Military. This kinda makes sense because she’s a military brat and her father is a General. This story is pretty cool so far. I don’t mind change as long as the story makes sense and the core of the characters are still intact. So far I have, I have no idea what to expect, but it’s getting good. Can’t wait for the next issue. Btw, Superman’s new suit looks dope!
