Abstract: Structure investigation of new wear-resistant composite materials based on polyolefins and industrial natural diamond powders are conducted. It is proved by experiments that the structural-phase response of adding the diamond particles with high degrees of fragmentation at perfluorinated and non-fluorinated polyolefins is different. Thus, depending on the qualitative and quantitative composition of the composites and the technological conditions of their production, the polymer forms different structural types - from the band with no apparent supramolecular structures to spherulitic.
