Blends based on the semicrystalline Poly(ether ether ketone) - PEEK and the amorphous Poly(ether imide) - PEI have been widely investigated for their outstanding mechanical, thermal and chemical-physical properties. The conformation of the PEI monomer affects the miscibility of the blends. Although the large interest in high demanding lightweight applications, foams from PEEK/PEI blend have not been considered until recently. The aim of this work was to prepare foams from PEEK/PEI miscible blends by using supercritical carbon dioxide. The role of blend composition on the density and the morphological parameters of the resulting foams was investigated.

Abstract
Blends based on the semicrystalline Poly(ether ether ketone) - PEEK and the amorphous Poly(ether imide) - PEI have been widely investigated for their outstanding mechanical, thermal and chemical-physical properties. The conformation of the PEI monomer affects the miscibility of the blends. Although the large interest in high demanding lightweight applications, foams from PEEK/PEI blend have not been considered until recently. The aim of this work was to prepare foams from PEEK/PEI miscible blends by using supercritical carbon dioxide. The role of blend composition on the density and the morphological parameters of the resulting foams was investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
