FTIR证据不支持确切的材料鉴定。最近的谱库命中是聚(乙烯亚胺)表氯醇改性物,但匹配置信度实际上不存在,并且没有任何直接或相关的文献证据独立支持该指定。观察到的光谱以3321 cm-1附近的宽谱带、1025 cm-1附近的谱带以及1900-2300 cm-1区域的几个弱特征为主,这些特征整体上更符合广泛的含杂原子有机物,可能带有氢键结合的O-H和/或N-H基团,而不是可靠鉴定的特定聚合物或硫杂环。
推荐的后续步骤: Recollect the FTIR spectrum with atmospheric CO2/H2O background control to check whether features near 2236 and 2334 cm-1 persist. Obtain a higher-quality fingerprint-region spectrum, especially 1800-700 cm-1, and compare for characteristic amine versus alcohol/polyol band patterns. Check for complementary evidence by Raman, elemental analysis, or XPS to determine whether nitrogen, sulfur, or chlorine is actually present. If a poly(ethylenimine)-type material is suspected, verify with wet-chemical amine testing or compare against authenticated PEI and epichlorohydrin-modified PEI reference spectra under the same measurement conditions.
