Singapore researchers turn plastic bottles into aerogel

The video tutorial explains the process of converting plastic bottles into aerogels. Initially, bottles are shredded and combined with chemicals like hydrochloric acid and poly vinyl acetate. The mixture is then sonicated and freeze-dried to form a soft, durable, and flexible aerogel. This aerogel can be treated for various applications, such as pollution masks or oil absorption, and can withstand high temperatures when coated with fire retardants.

What is the first step in the process of creating aerogel from plastic bottles?

• Shredding into fibers
