FTIR證據不支持明確的材料鑑定。最近譜庫匹配為環氧氯丙烷改質的聚(乙烯亞胺),但匹配信心實際上不存在,且沒有直接或相關的文獻證據獨立支持該歸屬。觀察到的光譜以3321 cm⁻¹附近的寬譜帶、1025 cm⁻¹附近的譜帶以及1900-2300 cm⁻¹區域的數個弱特徵為主,這些特徵總體上更符合廣泛的含雜原子有機物,可能帶有氫鍵O-H及/或N-H基團,而非已確認的特定聚合物或硫雜環。
建議的下一步: 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.
