Herein, a recyclable nucleating agent for poly(l-lactide) (PLLA) was fabricated via taking advantage of grafting biodegradable poly(3-hydroxybutyrate)-diol onto the surface of magnetic nanoparticles (ferroferric oxide, Fe3O4). Its effectiveness in improving crystallinity, gas barriers, thermal, and...
