Heat-sensitive materials like PVC, ABS, and EVOH, or engineering resins like acetals, PC, nylon, or polyesters are more likely to degrade than heat-tolerant polyolefins.

PVC、ABS和EVOH之类的热敏性材料或者POM、PC、尼龙或聚酯类的工程树脂比耐热性的聚烯烃更容易降解。

POMs and deys are still maintained integrallty.AFM exhibits the films is even.The thickness of each layer is about 1.25nm. The AFM images reflect that there are some protuberances on the outer surface layer of the film, which due to the aggregates of spherical structure PMo12. Cyclic Voltammograms reflects the redox potentials of dye in multilayer shifts towards more positive values than pure dye multiplayer which may be explained by charge transfer from dye to POM. Fluorescence spectra show that polyoxometalates caused the fluorescence decay of dyes, which maybe used as fluorescence sensors.

UV-VIS说明复合膜均匀生长； IR 光谱、XPS能谱研究结果表明，紫外光照前后，膜中多酸/染料分子间没有发生显著的光化学反应，各组分的结构仍然保持；原子力显微镜显示，膜的外表面是均匀的，每一个双层厚度大约是1.25nm，膜表面的隆起，可能是多酸阴离子簇堆积所引起；循环伏安测定结果表明，由于多酸阴离子的影响，有机染料的氧化还电位发生了正的偏移，反映出复合膜中染料分子与多酸阴离子间发生了荷移相互作用，导致染料分子失去部分电子而使氧化性略强；荧光光谱研究结果表明，多酸阴离子可以有效地引发荧光染料的荧光淬灭，这为多酸在荧光传感器方面的应用提供了有价值的信息。
