Dip or Step-Like Features in the Infrared Reflection Spectra of Heat-Treated Polyoxymethylene
When injection-molded polyoxymethylene is heat-treated below its melting point, it shows increased polarized reflection along the injection direction, as confirmed through micro-infrared spectroscopy. A characteristic dip or step-like structure appears around 940 cm . Previously, the origin of this...

| Abstract | When injection-molded polyoxymethylene is heat-treated below its melting point, it shows increased polarized reflection along the injection direction, as confirmed through micro-infrared spectroscopy. A characteristic dip or step-like structure appears around 940 cm
. Previously, the origin of this structure was unclear. However, we have found that it can be explained by refining the calculation model to account for the relative permittivity perpendicular to the sample surface. |
