摘要

这项研究探讨了化学战剂在聚合物涂层上的吸附和渗透，以评估其防护潜力。研究人员用两种二异氰酸酯三聚体合成了两种高度交联的脂肪族聚氨酯（PU），并使用石英晶体微天平消散法和气相色谱法分析了它们对甲基膦酸二甲酯（DMMP）和乙基硫化 2-氯乙酯（CEES）的吸附和渗透性。研究结果表明，每种药剂和聚氨酯都具有不同的吸附特性。与 DMMP 相比，极性更强的 CEES 具有更强的吸附性。与 Htri-PU（脂肪族结构）不同，IPtri-PU（脂环结构）的解吸附和再吸附几乎可以忽略不计，因此渗透率极低。因此，脂环族 PU 更有希望减少吸附和渗透。

Exploring the Chemical Permeation Resistance and Surface Adsorption Properties of Polyurethane Coatings

This work explores the adsorption and permeation of chemical warfare agents on polymer coatings to assess their protective potential. Two highly cross-linked aliphatic polyurethanes (PUs) were synthesized from two diisocyanate trimers, and their adsorption and permeation of dimethyl methylphosphonate (DMMP) and 2-chloroethyl ethyl sulfide (CEES) were analyzed using quartz crystal microbalance with dissipation and gas chromatography. The study revealed distinct adsorption properties for each agent and the PU. CEES, with higher polarity, exhibited greater readsorption compared to DMMP. IPtri-PU (alicyclic structure) showed negligible desorption and resorption, resulting in minimal permeation, unlike Htri-PU (aliphatic structure). Thus, alicyclic PUs are more promising for reducing adsorption and permeation.
