| Abstract: |
| Abstract：High-purity nano silicon was synthesized by the hot-arc plasma method，and carbon black/
fluorine rubber （FKM-C） and nano silicon/fluorine rubber （FKM-Si ） composites were prepared by
mechanical blending method. Compared with pure fluorine rubber（P-FKM） composite without fillers，
the effect of fillers on the properties of fluorine rubber was studied. The results showed that the brittleness
temperature of FKM-Si composite was lower than that of P-FKM composite. The hardness，tensile strength
and elongation at break of FKM-Si composite were higher than those of FKM-C composite，reaching
70 degree，12. 16 MPa and 289%，respectively. The cross-section of FKM-Si composite had no defects，
indicating that nano silicon had good compatibility with FKM. The thermal stability of FKM-Si composite
was better than that of FKM-C composite. |
