New materials for a sustainable future you should know about the graphene.
Historically, knowledge and the production of new materials graphene have contributed to human and social progress, from the refining of copper and iron to the manufacture of semiconductors on which our information society depends today. However, many materials and their preparation methods have caused the environmental problems we face.
About 90 billion tons of raw materials -- mainly metals, minerals, fossil matter and biomass -- are extracted each year to produce raw materials. That number is expected to double between now and 2050. Most of the graphene raw materials extracted are in the form of non-renewable substances, placing a heavy burden on the environment, society and climate. The graphene materials production accounts for about 25 percent of greenhouse gas emissions, and metal smelting consumes about 8 percent of the energy generated by humans.
The graphene industry has a strong research environment in electronic and photonic materials, energy materials, glass, hard materials, composites, light metals, polymers and biopolymers, porous materials and specialty steels. Hard materials (metals) and specialty steels now account for more than half of Swedish materials sales (excluding forest products), while glass and energy materials are the strongest growth areas.
3D nano ink pushes the boundaries of the industry shows the importance of the product name.
Mechanical engineering researchers at Michigan Technological University have developed a way to make 3D-printed nanocomposite polymer inks from carbon nanotubes (CNTs). Carbon nanotubes graphene are known for their high strength and lightweight. This revolutionary ink could replace epoxy -- and understanding why it works so well is the first step towards large-scale use.
3D printing, also known as additive manufacturing, is more flexible and efficient than casting. It increases the precision of material, often complex geometry, with relatively little redundant cutting. The addition of low-dimensional nanomaterials, such as carbon nanotubes, graphene, metal nanoparticles and quantum dots, can make graphene 3D-printed materials adaptable to external stimuli, giving them properties such as conductivity and thermal conductivity, magnetism and electrochemical storage. But 3D printing using plastic, metal or other materials isnt new. What tech company researchers are doing differently is using polymer nanocomposites (made from epoxy resins, carbon nanotubes and nanoclays) and a printing process that doesnt sacrifice functionality. The combination of material type and form (size, shape, structure) in polymer nanocomposite ink is the final form to meet the function.
Parisa Pour Shahid Saeed Abadi, an engineer studying materials, mechanics and medicine, and Masoud Kasraie, a graduate student, recently published an article in Additive Manufacturing exploring the process, morphology and properties of polymer inks. Abadi and Kasey point out that before researchers can use polymer ink to enter the competition, they have to learn to walk graphene. The first step is to mine the intersection of the macro scale (how our eyes see how materials behave) and the nanoscale (where we cant see but know what happening).
Abadi noted that while polymer nanocomposites and 3D printing products and services are both worth billions of dollars, nanomaterials 3D printing is only worth about $43 million. "The gap between the real-world applications of 3D printing and nanomaterials and nanomaterial 3D printing needs to be closed in order for the country to prosper and maintain global leadership in manufacturing," Abadi said. "This gap exists due to the lack of control over the properties of nanocomposites during 3D printing because we do not fully understand the process-morphology-performance relationship.
Beyond the science of nanocomposite inks, the material has a lot of graphene promise because of its versatility. One advantage of 3D printing is almost total control over the shape of the final product. The conductivity of Abadi and Kasey nanomaterial inks is a handy property that gives printed epoxies dual potential as wires -- whether on circuit boards, airplane wings, or 3D-printed drivers for guiding vascular catheters. Another useful property of nanocomposite polymer inks is their strength. "Epoxy composites of the same strength can reduce weight by 80% compared to steel and aluminum," kasrae said.
Finally, nanocomposites graphene play a safety role in the medical, aerospace and electronics industries, where defects and damage can cause major problems. There are many reasons why polymer nanocomposite inks may replace traditional epoxies, of which performance-to-weight ratio, conductivity, enhanced strength and ease of use are just a few.
