Reduction of friction and wear contributes significantly to energy saving for mech. system as considerable energy has been consumed in various forms of friction worldwide. In the present study, two kinds of dopamine-based oil-soluble polymers were synthesized by atom transfer radical polymerization (DOPA-BiBB-pLMA) and photopolymerization (DOPA-I2959-pLMA), and modified onto the Ti6Al4V sheet by the “”grafting to”” method. The characterizations of NMR, Fourier transform IR spectrum, water contact angle, and XPS confirmed that the polymers were successfully grafted onto the Ti6Al4V surface. Addnl., a series of tribol. tests were performed in oil environment using a universal materials tester under different exptl. conditions. It was shown that the coefficient of friction using the Ti6Al4V sheets grafted by the dopamine-based polymers was reduced by 23.5-46.2% compared with bare Ti6Al4V sheet. Furthermore, the wear depth and wear volume were also greatly decreased with the introduction of the dopamine-based polymers. DOPA-I2959-pLMA showed slightly better lubrication enhancement than that of DOPA-BiBB-pLMA, which may be attributed to the relatively higher polymerization degree. In summary, a universal “”grafting to”” surface modification approach was proposed bioinspired by catecholamine chem., which remarkably reduced friction and wear of the tribopairs with the introduction of oil-soluble polymers.
