Abstract

The Fe₃O₄/poly(lactide-co-glycolide) (PLGA) composites were prepared via a surface grafting technique. Initially, the poly(lactic acid) oligomer was synthesized and surface-grafted to Fe₃O₄ nanoparticles. Then, the grafted Fe₃O₄ particles were compounded with PLGA matrix by a simple solution blending method. The grafted Fe₃O₄ particles presented enhanced compatibility with PLGA matrix and the composites indicated enhanced dynamic mechanical performance. Electrochemical tests showed that the Fe₃O₄/PLGA composite coating can help improve the impedance of magnesium samples by 100-300%, and the impedance of the metal may be tunable by altering the components ratio of LA/GA within PLGA matrix. The composites may have potential application for magnesium alloy used in degradable medical implants.
