The present work reports, the use of plant-derived thermoset coating to control iron (Fe) corrosion in simulated body fluid for bone scaffolds applications by varying the curing temperature of the plant-derived polymers, namely poly[xylitol-(1,12-dodecanedioate)] (PXDD). The physicochemical characterizations of the scaffolds indicate that a different degree of crystallinity has been observed as P120[sbnd]Fe (PXDD cured at 120 °C and then coated on Fe) shows a more crystalline structure while P140[sbnd]Fe (PXDD cured at 140 °C) has a more amorphous nature. The amorphous form of P140[sbnd]Fe leads to expedited corrosion compared to P120[sbnd]Fe and pure Fe owing to the hydrophilic property and the higher hydrolysis effect in the former. The plant-derived PXDD could be a promising coating material to control the corrosion of Fe-based scaffolds for temporary bone implant applications.
