研究目的
Investigating the formation of amorphous carbon nanofibers on the surface of various commercial polymers under the action of a high-power ion beam of nanosecond duration at room temperature.
研究成果
The study demonstrated the formation of amorphous carbon nanofibers on the surface of certain commercial polymers under HPIB irradiation at room temperature. The findings suggest a potential method for synthesizing carbon nanomaterials from low-cost precursors, though the growth mechanism requires further investigation.
研究不足
The study is limited by the understanding of the growth mechanism of CNFs under HPIB irradiation, which is not yet fully understood. Additionally, the formation of CNFs was not observed on all polymers studied, indicating material-specific limitations.
