▎ 摘　　要

Since more than half century ion beams are used for modification of functional properties of various materials: after semiconductors, metals and ceramics ion irradiation appeared recently as an interesting method of modification of organic materials, especially for friction and wear properties. Among polymeric materials the newest area of applications of ion beams is their use for modification of elastomers, commonly known as rubbers. Main structural effect caused by heavy ions in polymers is a massive loss of hydrogen from the surface layer, this leads to a smoothening and shrinking of the sample surface. The paper describes the results obtained in several rubbers modified by ion beams. Both, pristine and graphene-reinforced rubber samples were used, graphene doping led to the strengthening of the material bulk whereas ion irradiation allowed for surface property improvement. In the first part of the paper the hydrogen release from irradiated elastomers is shortly presented. Mechanical properties (hardness and friction) are discussed in the second part.
