Stress-strain curves of a few polymers Elastic materials that are isotropic in their underformed state can be described by the fundamental elastic constants. Polymers portray the mass properties of polymer materials and have a place with the field of polymer physical science as a subfield of material science. In most organic molecules, however, the valence electrons are localized, due to their participation in the intra-molecular bonds between the atoms. By borrowing from nature's ability to influence inorganic microstructures in biomineralization processes and in the hydrothermal synthesis of complex minerals, a new class of materials in which organic components exert a role in controlling inorganic microstructure is evolving.
