Electrophoretic deposition
Electrophoretic deposition is like when you color a picture with markers.
Imagine you have a coloring book page that you want to color in, but you don't want to use markers or crayons. Instead, you fill a cup with very tiny particles of the color you want to use. These particles are so small that you can't even see them!
Now, you dip a special piece of paper into the cup of particles, and then you attach it to a charger. Just like how a magnet has two ends that attract or repel each other, every particle in the cup is either positively charged or negatively charged.
So, when you attach the colored paper to the charger, it creates an electric field. This electric field pulls all of the particles to one end of the paper, because the opposite charges attract each other.
Once all of the colored particles are stuck to one side of the paper, you take it out of the cup and wait for it to dry. After it's dry, you can peel the colored paper off, and you'll have a page that's been colored in with tiny, invisible particles!
This process is called electrophoretic deposition, and it's used to create all sorts of things, like coatings on metals or ceramics, or even to make electronic components like solar cells.
