origin
Pyotr Alexandrowitsch Rehbinder comes from a widespread German-Baltic family . His great-grandfather Pavel Maximowitsch ( Russian Павел Максимович Ребиндер , 1803-1866) was a lawyer in the Russian War Ministry. His brother Alexei Maximowitsch ( Russian Алексей Максимович Ребиндер , 1795–1869) was a Russian lieutenant general and entrepreneur. Both father was Otto Friedrich von Rehbinder (* 1750) from Livonia , who adopted the name Максим Карлович Ребиндер when he converted to the Orthodox faith .

During the German-Soviet War Rehbinder did research for the armaments of the Red Army . After the war, in addition to research, he was also involved in leading bodies of the state apparatus with scientific organization.
Rehbinder published more than 500 scientific articles. In 1928, Rehbinder discovered a physical-chemical phenomenon that is now called the “Rehbinder effect” after him. The Rehbinder effect describes the change in the mechanical properties of a material under the influence of surface-active chemical substances that have been adsorbed on the surface. One speaks of a Rehbinder effect if the strength in the plastic area is reduced. This is used, for example, by adding surfactants when drilling and cutting materials. Rehbinder observed this with certain metal wires in paraffin, which contained some oleic acid.
