Electrical conductive poly(phenylene sulfide) (PPS)/fullerene (C 60 ) composites were prepared by 1-chlornaphthalene blending method, and the interface effects of C 60 and PPS on PPS/C 60 properties were characterized. C 60 is an excellent nanofiller for PPS, and 2 wt% PPS/C 60 composite displayed the optimal conductivity which achieved 1.67 × 10 −2 S/cm. However, when C 60 concentration reached 2 wt%, the breaking strength and tensile modulus of PPS/C 60 fiber achieved maximum 290 MPa and 605 MPa, and those values were 7.72 and 11.2 times as that of pure PPS. The excellent conductive and mechanical properties of PPS/C 60 were attributed to the heterogeneous nucleation of C 60 during PPS crystallization, formation of a large number of covalent bond by main C 60 -thiol adducts and minor C 60 -ArCl alkylation between C 60 outer surface and PPS matrix. At same time, PPS/C 60 thermal properties were also investigated.
