moisture and proteins
Super glue bonds skin because its monomers react with moisture and proteins on the skin's surface, forming strong polymer chains that integrate with your skin. This reaction is triggered by water molecules and the negative regions of collagen proteins.
- 💧 The polymerization is initiated by water molecules, which are abundant on skin and in the air.
- 🧬 Collagen proteins in skin have negative regions that directly initiate the polymerization reaction.
- 🩹 Medical-grade super glue uses longer carbon chains to slow the reaction, reduce heat, and increase flexibility for wound healing.
- 🧪 Acetone (nail polish remover) can dissolve super glue, but it's not recommended for eye contact.
- ♻️ Future applications explore using super glue's depolymerizable nature to create a truly recyclable plastic.
