Ionic bonds in macromolecules
WebProperties such as mechanical resistance, swelling, permeability, chemistry, and thermal stability as well as the rate of release of encapsulated substances are strongly influenced by cross-bonding. Depending on the nature of the cross-binding, the main interactions involved in tissue formation are covalent or ionic [24,106,107].
