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.

An attachment theory frame meets the road map for therapy!
Format: Hardcover
Dr. Sue Johnson's scholarly synthesis of attachment theory and research, alongside her own clinical reflections/examples, culminates in a truly excellent resource! Dr. Johnson describes the value and utility of attachment theory so eloquently-- the wisdom contained within this text resonates deeply with the human experience and what we know to be true about the inherent and powerful longing for connection. She offers a helpful road map for therapy that is relevant, necessary, and essential for healing and change in therapy!

Wonderful read
Format: Hardcover
This is a super read for anyone interested in understanding more about relationships. It is not a popular press magazine or cookbook. Be aware it is written in a very dense (though fluid) academic style which requires your attention: compound sentences cleaned of articles and misunderstanding. The content is wonderfully organized and flawlessly edited. As a nonprofessional, I enjoyed the book immensely, finding insights into past relationships and myself on almost every page -- along with hope for doing better by my partner in the future.

Five stars
Format: Hardcover
The book was packaged well and arrived in perfect condition. It also arrived early which was great. I recommend this book seller. I read Susan M. Johnson’s other book on EFT, “Hold Me Tight” and found it extremely helpful with my therapy clients. I’m excited to dive into this book too!

This would have been great if an editor worked on it first
Format: Hardcover
As much as I admire Dr. Johnson and her work, the writing is not good in this book. The ideas are very useful but the reader must slog through complex, turgid sentences and multiple grammatical errors to get the points. I wish more writers had good editing and didn’t submit such poor writing for publication. Dr. Johnson is not alone in this criticism. I think many writers have been trained to write circuitous sentences and that results in the reader working unnecessarily hard to grasp the meaning of the ideas. That said, I am very impressed by her use of research that supports her writing and the ideas she presents. I hope that future publications are more carefully edited before they are published, with the reader in mind. And if you wonder if I am uneducated, rest assured that I have a doctorate in clinical psychology and 20 years post license experience.

Great!!!
Format: Paperback
This book I feel really gives a great understanding of key topics and points that would potentially be on the exam. Although vague for some folks, potentially, they would be things to know and keep in mind when considering to cost of such an exam.
