Mechanical and dynamic mechanical properties of polyurethane/Fe-octacarboxyl acid phthalocyanine...

In this paper, Fe-octacarboxyl acid phthalocyanine (Fe-OCAP)/polyurethane (PU) blends were prepared by solution blending. The mechanical and dynamic mechanical properties of the samples were evaluated by tensile tests and dynamic mechanical analysis. The results showed that incorporation of Fe-OCAP significantly improved the tensile strength,...
