Sorption of dimethyl methylphosphonate within Langmuir-Blodgett films of trisilanolphenyl polyhedral oligomeric silsesquioxane

Article Abstract:

Trisilanolphenyl polyhedral oligomeric silsesquioxane (POSS) molecules are used to create well-ordered Langmuir-Blodgett films containing silanol groups that interact strongly with dimethyl methylphosphonate (DMMP). Results indicate a low uptake probability, however in a DMMP-saturated atmosphere, the organophosphonate molecules are capable of diffusing into and adsorbing within the films.
