该光谱与含羰基的酯类材料最为一致,谱库将聚丙烯酸乙酯列为最接近的命名候选物。然而,整体匹配强度非常弱,且没有直接参考文献或相关文献支持确凿的材料归属。观察到的谱带支持广泛的含酯有机成分,可能属于丙烯酸酯或聚酯类方向,但现有证据不足以具体确认聚丙烯酸乙酯。
推荐的后续步骤: Recollect or inspect the full FTIR spectrum, especially the 1500-600 cm⁻¹ fingerprint region, to verify ester C-O-C band patterning and look for polymer-specific backbone features. Compare the sample directly against authenticated spectra of Poly(ethyl acrylate), a generic acrylic polymer, and representative aliphatic polyesters such as poly(butylene adipate). If the sample is a coating, adhesive, or extractable residue, run complementary analysis such as ATR-FTIR repeat measurement, DSC, or Py-GC/MS to distinguish an acrylate polymer from a polyester or small-molecule ester. Check for repeatable carbonyl peak shape and position across replicate measurements, since ester subclass assignment often depends on the detailed carbonyl and C-O band profile.
