摘要：
The data of thermodesorption mass spectrometry indicate that fullerene C60 molecules are desorbed from a polyimide (PI) surface at temperatures below the PI decomposition onset temperature, while the desorption of C60 from the bulk begins in the temperature region of the polymer decomposition. It is suggested that strong chemical bonds between C60 and PI macromolecules are formed in the bulk in the stage of the polyamic acid preparation and are broken upon destruction of the polymer macromolecules. The character of C60 thermodesorption from the PI surface depends on thickness of the surface film of fullerene C60.
