polymernetzwerk
A polymernetzwerk, or polymer network, is a three-dimensional, crosslinked assembly of polymer chains in which individual chains are connected by covalent bonds or strong physical associations. The crosslinks prevent dissolution in most solvents and give rise to a gel-like or solid material with a defined elastic response. The density of crosslinks—the crosslink density—and the topology of the network determine swelling, stiffness, and thermal behavior.
Networks can be broadly categorized as permanent covalent networks (thermosets) or reversible/dynamic networks (physically crosslinked or
Physical properties depend on crosslink density and polymer flexibility. In swollen networks, the network equilibrium swelling
Applications span bioengineering (tissue scaffolds, drug delivery hydrogels), contact lenses, seals and gaskets, soft robotics, membranes,
