Synthesis and characterization of Fe sub(3)O sub(4)/poly(lactide-co-glycolide) composite and its coating effects on magnesium alloy
The Fe sub(3)O sub(4)/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 Fe sub(3)O sub(4) nanoparticles. Then, the grafted Fe sub(3)O sub(4) particles were compounded with PLGA...

description | The Fe sub(3)O sub(4)/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 Fe sub(3)O sub(4) nanoparticles. Then, the grafted Fe sub(3)O sub(4) particles were compounded with PLGA matrix by a simple solution blending method. The grafted Fe sub(3)O sub(4) particles presented enhanced compatibility with PLGA matrix and the composites indicated enhanced dynamic mechanical performance. Electrochemical tests showed that the Fe sub(3)O sub(4)/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. POLYM. COMPOS., 37:1369-1374, 2016. copyright 2014 Society of Plastics Engineers |
