Title: morphology Long Title: IUPAC Gold Book - morphology DOI: 10.1351/goldbook.MT07285 Status: current Definition Shape, optical appearance, or form of phase domains in substances, such as high polymers, polymer blends, composites, and crystals. Note For a polymer blend or composite, the morphology describes the structures and shapes observed, often by microscopy or scattering techniques, of the different phase domains present within the mixture.
