Three-dimensional printing of cellulose nanofibers reinforced PHB/PCL/Fe3O4 magneto-responsive shape memory polymer composites with excellent mechanical properties

The combination of shape memory polymer composites and 3D printing technology provides novel opportunities for customized manufacturing and intelligentization of products. Here, we developed magneto-responsive shape memory polymer composites with well-balanced strengths and toughness by adding Fe3O4 and cellulose nanofibers (CNFs) to a poly-hydroxybutyrate/poly(ε-caprolactone) blend as functional particles and reinforcing component. The...
