Polymer
Term: Polymer
Category: Chemistry
Definition: A polymer is a very large molecule made when many small molecules called monomers join together through strong chemical bonds. They can be of natural or synthetic type. Their chains can be arranged in different ways: mostly straight (linear), with side branches (branched), or connected into a network. The physical and chemical properties of a polymer depend on the type of monomers, bonding pattern, and chain length.
Common Polymers Used in Coatings: PEG, PVP, PU
How it Works:
Polymers are formed through polymerization reactions, where monomers join via addition or condensation mechanisms.
- Addition polymerization: Monomers with double bonds add to one another without forming by-products.
- Condensation polymerization: Monomers with two reactive ends combine while releasing small molecules such as water or methanol.
Once polymerized, the resulting chains can interact through hydrogen bonding, van der Waals forces, or crosslinking, giving the material its unique properties.
Common Uses:
- Development of medical devices, implants, and drug delivery systems
- Fabrication of hydrogels, biodegradable films, and tissue scaffolds.
- Production of adhesives, coatings, and elastomers in biomedical and industrial applications.
- Creation of smart polymers responsive to pH, temperature, or stimuli for advanced biomedical technologies.
