Makromolekyyliverkosto, known in English as a macromolecular network, is a three-dimensional structure formed by interconnected macromolecules. These networks can be created through various chemical or physical processes, leading to materials with unique properties. In a chemical network, covalent bonds form between polymer chains, resulting in a permanent and often rigid structure. This is common in thermosetting plastics and cross-linked polymers. Physical networks, on the other hand, are formed by non-covalent interactions such as hydrogen bonds, van der Waals forces, or ionic interactions. These interactions are reversible, allowing the network to be influenced by changes in temperature, pH, or solvent. Hydrogels are a prime example of physical networks, where a hydrophilic polymer network swells to absorb large amounts of water. The density and type of cross-links in a macromolecular network significantly influence its mechanical strength, elasticity, permeability, and thermal stability. These networks find applications in diverse fields, including advanced materials, drug delivery systems, tissue engineering, and separation technologies. The study of macromolecular networks is crucial for understanding and designing materials with tailored functionalities.
