摘要

•CaO nanoparticles were successfully organically modified with oleic acid (Ol-CaO).•CaO and Ol-CaO were incorporated into PLA at 5 and 8 wt.% by a melting process.•Microhardness increased ca. 9% in PLA/Ol-CaO nanocomposites.•PLA/Ol-CaO showed exceptional antimicrobial properties against E. coli bacteria.•CaO nanoparticles promoted the degradation of PLA after irradiation for five days.
