Hybrid polymer
Hybrid polymers (hybrids: Latin: “of two different origins”) are polymeric materials that combine structural units of different material classes on a molecular level.
Due to their structure, hybrid polymers can have completely new combinations of properties. In contrast to composite materials (defined phase boundaries, weak interactions between the phases) and nanocomposites (use of nanoscale fillers), the structural units of hybrid polymers are linked to one another on a molecular level. This is achieved through chemical processes such as B. the sol-gel process , with which inorganic networks can be built. Through the use of organically reactive precursors z. B. organically modified metal alkoxides, organic oligomer / polymer structures can also be produced.
These combination options expand the range of application of classic composite materials and are the basis for the multifunctionality of materials that is often required today.
The Fraunhofer-Gesellschaft carries this type of substance under the brand name ORMOCER ® e.
