Polymeriverkostot, often translated as polymer networks, are three-dimensional structures formed by the cross-linking of polymer chains. These cross-links create a resilient and often elastic material where the individual polymer chains are held together, preventing them from flowing past each other. This interconnectedness is the key feature that defines a polymer network.

The properties of polymer networks are highly dependent on the type of polymers used, the density of cross-links, and the nature of the cross-linking process. For example, a high cross-link density can lead to a rigid and brittle material, while a lower density might result in a more flexible and rubbery substance. The cross-links can be formed through various chemical reactions, such as covalent bonding, ionic interactions, or physical entanglements that are sufficiently stable.

Polymer networks find applications in a wide range of fields. They are essential components in elastomers, which are highly elastic materials like rubber used in tires and seals. They are also used in hydrogels, which are water-swollen polymer networks that are biocompatible and utilized in contact lenses, drug delivery systems, and tissue engineering scaffolds. Furthermore, thermosetting polymers, which form permanent, rigid networks upon curing, are employed in adhesives, coatings, and structural composites due to their high strength and thermal stability. The ability to tailor their properties through controlled cross-linking makes polymer networks versatile materials for numerous technological advancements.
