New Corrosion Coating Solution Is Great For Healing Scratches & Cracks | Valdamark VCI
Researchers at Northwestern University have developed a new novel coating material which can self-heal within seconds after being scratched, scraped, or cracked.
Here’s how it works — and how it could be one day be used to protect valuable infrastructure from corrosion.
Its interesting to think that when we refer to materials and their ability to withstands scratches and scrapes, we usually use words like toughness and durability. Referring to a materials ability to hold out against abrasion.
The reason for this is because most materials are unable to heal their damages once it occurred. Obvious right?
Well not now, Researchers at the Northwestern University have truly broken the mold when it comes to a material being able to ‘fix’ itself.
Indeed they have broken the mold by err, not breaking it,.!
Rather that exhibiting permanent damage when scraping or scratching occurs etc they have developed a novel material than can heal itself in seconds.
The end goal for this breakthrough is to hopefully one day be corrosion prevention method that can help eliminate the kind of damage that occurs to big structures.
The unique thing about is that unlike other preventative products the oil does not drip, bonds very well and can rapidly heal when damage occurs.
This self healing coating can be used to prevent the corrosion of metals with an easy surface application.
The breakthrough was achieved by modifying an oil solution with light & hollow Graphene particles. Measuring just microns in size the particles build a network in the oil which prevents the oil solution from shrinking or dripping.
However when a scratch occurs they still allow oils to flow when the network and bonds are broken. This then heals the area that is damaged.
In fact researchers found that this corrosion prevention solution was able to keep to performing long after it was applied. The exact same spot was re scratched over 200 times repeatedly. Still it returned to original state, visible undamaged.
The lab at Northwestern University has warned against too much hype for the material. It is early days still.
The material has only been demonstrated on small surface area samples. Though they not foresee problems when scaling up extensive testing still needs to be done.
One future application could be for emergency underwater repairs where metal coatings have been damaged.
Corrosion Coating Solution
Corrosion is a big problem, costing a lot of money. A lot of effort goes into protecting things from getting rusty or damaged. One solution is to use special coatings that can stop corrosion. We'll talk about a new type of coating called "Amphiphilic antifouling coatings" that can help in a big way.
A Breakthrough Coating
A group of scientists has made a special coating that is activated by seawater. It's a blend of three things: a polymer called PTMH, polydimethoxysilane, and an isocyanate crosslinker. This coating can change when it touches seawater, making it work better and last longer.
Outstanding Resistance to Biofilm
This coating can resist the growth of biofilms, which are like slimy stuff that can harm things. It does this because of PTMH and how it can break down over time. Even after being in seawater for a whole month, it doesn't soak up much water.
Corrosion Coating Solution in Action
The scientists who made this coating shared their findings in a famous journal. It's a big deal because it could help save a lot of money and protect important stuff from corrosion.
The Cost of Corrosion
Every year, people spend a lot of money, around $2.5 trillion, to stop things from getting rusty. That's a huge amount, about 3.4% of all the money made in the world. It's a big deal because we need to keep our things safe from corrosion. Coatings play a big role in this.
Different Kinds of Coatings
There are many types of coatings used in different industries. Some are for making things look good, and some are for heavy-duty protection. The type of coating used depends on how bad the corrosion is likely to be.
The Competitive Coating Market
In the world of coatings, there's a lot of competition. Companies that make coatings for everyday stuff have to keep prices low. On the other hand, coatings for really tough conditions, like the ocean, don't have as much competition and can charge more.
Regional Differences
Asia-Pacific is the biggest market for coatings because they use a lot of them. In North America, they're using more coatings in manufacturing. This is because the oil and gas industry is growing.
Regulations and Trends
Coatings are facing more rules from the government to be cleaner and safer for the environment. People are using coatings that have fewer chemicals that can harm the air. Companies are also trying to make coatings that last longer and are easier to use.
In a world where corrosion costs a lot of money and can damage important things, coatings are a valuable solution. This new amphiphilic antifouling coating is a promising innovation that can help protect against corrosion. It's essential to keep finding better coating solutions to safeguard our assets and the environment.
