Materials Project:
For this project we had three options: to improve an already existing material, to write an article about a material that has been important over history, or researching and writing an article on a new material that isn't very well known.
I choose the first option, improving an already existing material. I did my project on improving the anti-fog on swimming goggles.
Reflection:
Anti-fog chemicals are continuing to be used more and more, in the past these chemicals were known but not used very often, mostly because we had nothing to put it on. But now there are countless products that require or use anti-fog chemicals such as swimming goggles, deep sea diving masks, any sport where you in the water, lenses, mirrors, glasses, etc. Anti-fogging agents and chemicals have helped shape our past, present, and future because it helps break down and repel water from things that we don't need water on. It will also be improved so that maybe one day, something fogging up will be non-existent.
A hydrophobic element is made up of molecules that repel the mass of water. The molecule’s physical and chemical properties cause it to not only repel water but also make water more strongly attracted to itself, which makes it form droplets. A hydrophobic molecule tends to be non-polar, which means that it will only align with other non-polar molecules, water is a polar molecule, which explains why hydrophobic elements repel water. A hydrophilic element is the exact opposite, made up of molecules that love, are attracted to, and are dissolved by water. This molecule’s physical and chemical properties cause it to attract water. A hydrophilic molecule is polar, which means they will line up with other polar molecules, like a magnet. Water, again, is a polar molecule which explains why hydrophilic elements have the properties they do.
