摘要：

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, elongation at break, and thermal deformation property of PU matrix. The interaction between Fe-OCAP and PU was investigated by infrared analysis. The result indicated that strong hydrogen bond was formed between Fe-OCAP and hard segments of PU and increased with increasing Fe-OCAP content. Quantitive evaluations of the interaction between Fe-OCAP and PU were conducted by analyzing the physical cross-linking density in samples. The results indicated that the physical cross-linking density of the samples was increased with increasing Fe-OCAP content. (C) 2012 Elsevier B.V. All rights reserved.
