AbstractWe designed a photo-controlled degradative coating of polypyrrole (PPy)/ polycaprolactone (PCL) hybrids on biodegradable MgSr alloy. The photothermal effects of PPy inspired by near-infrared light (NIR) irradiation (808 nm) can locally heat the coating to the low melting-point temperature required for PCL within 6 min, which can quickly heal the scratched defects and contribute to control the degradation behaviors of magnesium alloy. The scratched region can get desired recovery of its corrosion resistance after NIR irradiation, as a result of the synergistic function of low-melting-point deformation of the coating matrix and photothermal effect of PPy.
