Characterization of poly(2,6-diphenyl- p -phenylene oxide) films as adsorbent for microfabricated preconcentrators
Abstract(#br)This work aims at evaluating poly(2,6-diphenyl- p -phenylene oxide) (Tenax TA), in the form of thin films, as an adsorbent material for various analytical applications. The physical properties of the polymer were studied with regard to surface topography, crystal structure, and thermal stability. Films deposited from solution at different substrate temperatures were studied and compared to the granular form of the polymer. It was found that Tenax TA deposited from solution have a different topography compared to their granular counterpart.
