Abstract
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.
期刊介绍：
Langmuir is an interdisciplinary journal publishing articles in the following subject categories:
Colloids: surfactants and self-assembly, dispersions, emulsions, foams
Interfaces: adsorption, reactions, films, forces
Biological Interfaces: biocolloids, biomolecular and biomimetic materials
Materials: nano- and mesostructured materials, polymers, gels, liquid crystals
Electrochemistry: interfacial charge transfer, charge transport, electrocatalysis, electrokinetic phenomena, bioelectrochemistry
Devices and Applications: sensors, fluidics, patterning, catalysis, photonic crystals
However, when high-impact, original work is submitted that does not fit within the above categories, decisions to accept or decline such papers will be based on one criteria: What Would Irving Do?
Langmuir ranks #2 in citations out of 136 journals in the category of Physical Chemistry with 113,157 total citations. The journal received an Impact Factor of 4.384*.
This journal is also indexed in the categories of Materials Science (ranked #1) and Multidisciplinary Chemistry (ranked #5).
