摘要

微红外光谱证实，在熔点以下对注塑成型的聚氧乙烯进行热处理后，其沿注射方向的偏振反射增强。在940 cm-1附近出现典型的倾斜或阶梯状构造。在此之前，这种结构的起源并不清楚。然而，我们发现它可以通过改进计算模型来解释垂直于样品表面的相对介电常数。

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^-1. 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.
