There are limited kinds of constituent elements in organic materials, so the large number of organic compounds and their ever-changing complex properties depend more on the structure of functional groups in the material molecules. For example, hydroxyl in ethanol, carboxyl in carboxylic acid, amino and carboxyl in amino acid are the main structural factors that determine the basic properties of the above three compounds.
Relationship between functional group structure and material properties
The properties of functional polymer materials mainly depend on the functional groups contained in them.
The oxidation properties of polymer oxidants are derived from oxycarboxyl groups.
The polymer material containing N,N-disubstituted bipyridine structure has electroluminescence function.
Polymer materials containing quaternary amine and sulfonic acid groups have ion exchange function.
The hydrophilic, oleophilic, soluble and magnetic properties of polymer materials are related to the structure of functional groups to a certain extent.
The introduction of different functional groups can also improve the physical properties of polymer materials such as mechanical strength and glass transition temperature.
