Chitin based polyurethanes using hydroxyl terminated polybutadiene, Part II: Morphological studies.

Highlights: [•] Chitin based polyurethane (PU) using (HTPB) was prepared. [•] The FT-IR analysis confirmed the crosslinking behavior of the material [•] The SEM images also confirmed the cross-linked and non-cross-linked structure. [•] EDX–SEM analysis also supported the FT-IR and SEM analysis. [Copyright &y& Elsevier]
