普通FTIR搜索不支持对该样品的明确材料识别。最近的谱库名称是聚(乙烯亚胺),环氧氯丙烷改性,但匹配置信度实际上为零,并且没有直接或相关的文献证据证实该特定归属。测量光谱更安全地描述为含氮、羟基化或含醚的有机材料,具有脂肪族C-H谱带和额外的含羰基特征,与聚合物或树脂样组成一致,而不是一个有信心的单一谱库实体。
推荐的后续步骤: Re-measure the FTIR spectrum with improved baseline quality and broader sample preparation control, especially to confirm the shape and intensity of the 3329, 1728, and 1643 cm-1 bands. Check whether the 1643 cm-1 feature decreases after thorough drying; if it does, adsorbed water is contributing and the remaining functional-group assignment will be clearer. Collect complementary Raman or solid-state NMR data to distinguish polyamine, polyalcohol, and polyether character. If the sample is soluble, use NMR or LC/MS after suitable preparation to determine whether the 1728 cm-1 band comes from ester/carbonyl modification or from a separate additive.
