Simultaneously enhanced heat dissipation and tribological properties of polyphenylene sulfide-based composites via constructing segregated network structure
文献摘要：
Self-lubricating polyphenylene sulfide(PPS)composites were fabricated by constructing a segregated net-work structure using the co-deposition method.Both carboxyl-functionalized multi-walled carbon nan-otubes(CNTs)and silicon carbide(SiC)were successfully coated on the surface of PPS powders with the aid of self-polymerization of dopamine(PDA)and co-polymerization between PDA and polyethyleneimine(PEI),thereby forming PPS@PDA-CNTs-SiC hierarchical reinforcing hybrids.Results showed that the ther-mal conductivity of PPS@PDA-CNTs-SiC(0.97 W/(m K))is about 120％higher than that of PPS/CNTs/SiC.The friction coefficient(0.193)and specific wear rate(2.50×10-5 mm3/(N m))of PPS@PDA-CNTs-SiC are 18.9％and 50％lower than those of PPS/CNTs/SiC,respectively.The enhanced thermal conductivity of PPS@PDA-CNTs-SiC contributes to rapid dissipation of frictional heat at the sliding interface which protects the polymer substrate from being destroyed or peeled,thereby improving the tribological per-formance.This work provides new insights into expanding the application of self-lubricating polymer composites in the fields where efficient heat dissipation is also a primary concern.
