谱库顶部匹配为Poly(ethylenimine),epichlorohydrin modified,但整体匹配强度非常弱,没有直接或相关的文献证据独立确认该具体材料。观察到的FTIR模式更安全地描述为含氮脂肪族聚合物材料,显示在3294 cm-1附近的N-H/O-H伸缩谱带、2922和2853 cm-1的脂肪族C-H谱带、1645 cm-1附近与胺相关弯曲和/或结合水贡献一致的谱带,以及在1226和1034 cm-1处适用于C-N和/或C-O单键振动的强烈指纹区吸收。由于顶部谱库模式还包括聚乙烯醇、聚环氧乙烷和环氧氯丙烷/环氧乙烷相关聚合物,可辩护的结论是更广泛的含胺脂肪族聚合物方向,而非对命名谱库化合物的明确归属。
推荐的后续步骤: Re-run the FTIR spectrum with improved background correction and drying of the sample to assess whether the 3294 and 1645 cm-1 bands decrease, which would help separate true N-H/O-H functionality from moisture effects. Inspect the 1200-900 cm-1 region at higher spectral quality, since resolving the relative strengths and shapes of the 1226 and 1034 cm-1 bands may help distinguish C-N-rich from C-O-rich polymers. If available, compare against authenticated spectra of Poly(ethylenimine),epichlorohydrin modified, poly(vinyl alcohol), and poly(ethylene oxide) measured under the same conditions. Use a complementary method such as elemental analysis or XPS to test for nitrogen; confirmation of nitrogen would strongly favor the amine-containing polymer direction over oxygen-only candidates such as poly(vinyl alcohol) or poly(ethylene oxide).
