| 英文摘要 | In this study, to achieve a homogeneous dispersion of nanodiamond (ND) in a polyimide (PI) matrix and a strong interfacial adhesion between ND and the PI matrix, a biomimetic nondestructive dopamine chemistry was employed for surface modification of ND. FTIR and Raman spectroscopy studies revealed that self-polymerization of dopamine could produce thinner polydopamine (PDA) layers on the ND surface via spontaneous oxidation and the intermolecular cross-linking reaction of PDA molecules. The structure and morphology of PDA-ND were studied by FTIR, SEM, and Raman spectroscopy, which verified the p-p interactions between PDA and ND. The facile dispersion of PDA-ND in a polyamic acid prepolymer made it possible to obtain PI/ND composites with no obvious ND aggregation. The effect of PDA-ND nanoparticles on the thermal, mechanical and tribological properties of the resulting PI/PDAND composites were evaluated, and the results showed that the incorporation of PDA-ND could increase the hardness, tensile strength, storage modulus, as well as the wear resistance properties. PI/PDA-ND composites prepared in this study showed that PDA-ND is a promising nanoreinforcing filler for PI composites. |
