Product Overview

 

Graphene oxide (GO), also known as graphene oxide, is a type of derivative in the process of transforming graphite into graphene. It is a layered material obtained by ultrasonic exfoliation, dispersion, and pulverization of oxidized graphite. It was discovered by Oxford University chemist Benjamin Brodie in 1859.

Graphene oxide is a two-dimensional structured nanomaterial with a single atomic layer thickness, composed of sp2 and sp3 hybridized carbon atoms. Its structure contains various oxygen-containing hydrophilic functional groups such as hydroxyl, carboxyl, and epoxy groups, and has good dispersibility in aqueous media.

The main methods for preparing graphene oxide include oxidation, solvent exfoliation, chemical vapor deposition, micro mechanical exfoliation, metal surface epitaxy, etc. Among them, the most simple, low-cost, and capable of large-scale production method is oxidation. Oxidation methods are divided into Staudenmaier method, Brodie method, Hummers method, Offerman method, etc.

Due to its low preparation cost, good film-forming properties, large specific surface area, and easy functionalization, graphene oxide has broad application prospects in fields such as energy storage, batteries, photocatalysis, biomedicine, sensors, water treatment, and is widely used in modified polystyrene, polypropylene, polyurethane, polylactic acid, polymethyl methacrylate and other foaming materials.

Product Features

1. Good dispersibility: Graphene oxide has good dispersibility in aqueous media, which makes it easier to mix with other materials in many applications.

2. Easy functionalization: Its surface contains various oxygen-containing functional groups, such as hydroxyl, carboxyl, and epoxy groups, which can be modified through chemical reactions to endow graphene oxide with new properties.

3. Multiple active sites: During the preparation reaction process, a large number of active sites are generated, which facilitates interactions with other substances.

4. Special optical properties: Graphene oxide has a certain absorption in the visible light range, and its optical properties can be adjusted by changing its structure and functional groups.


Application Fields

 

Graphene oxide is a novel carbon material with excellent performance and rich surface functional groups, which has a wide range of applications in the following fields:

Electronic products: Many electronic devices can be manufactured using graphene oxide as one of the basic materials for their components, and field-effect transistors using reduced graphene oxide have been used as chemical and biological sensors.

Energy reserve: Nanocomposites of reduced graphene oxide have been used for high-capacity energy storage in lithium-ion batteries. Large surface area reduced graphene oxide can be used as an energy storage material in supercapacitors.

Biomedical: One application of graphene oxide in the biomedical field is as an element in drug delivery structures. Functionalized nano graphene oxide can be used for targeted distribution of anticancer drugs.

Biosensors: Graphene oxide, as a fluorescence quenching material, can be applied to biosensors with fluorescence resonance energy transfer effect.

Environmental protection: Graphene oxide based composite materials can be used to treat harmful gases and convert air pollutants into useful energy resources.

Helpful and interesting introduction
Format: Paperback
This is a good quick introduction. A good supplement to a course on modernist literature or art. What is important is that it shows the Modernist project as something that encompassed art, literature, psychology, science, and politics--in other words, it contextualizes the movement.

So glad I bought this!
Format: Paperback
I am a lit teacher at an independent school, and was able to use this book to link the literature and the art of the modern movement. My students loved this project - they made their own artwork for a display at school!

Very good comprehensive introduction to Modernism
Format: Kindle
Very good comprehensive introduction to Modernism. Only not too helpful for me at the moment becasue I was looking for something more specific. Butler has this wonderful ability to make connections between the arts. He constructs a bigger picture of the Modern movement where many forms are interlinked, influenced and informed one another. He also has a longer book Early Modernism that might be more helpful if you are looking for indepth and moe detailed discussions.

Delivers on its title
A concise overview of a very big and very slippery subject. Covers a lot of ground with enough information to give the reader reason to explore for herself.
