Abstract
Nitrile butadiene rubber (NBR) is commonly found as the main polymer in rubber gloves. This experiment is studying the effect of crosslinking density on the permeation of small organic molecules, specifically ethanol, through NBR. The diffusion coefficients were obtained for ethanol to permeate through NBR films prepared with different crosslinking densities. Such diffusion coefficients were correlated with the free volumes in the polymer samples, which were measured via positron annihilation lifetime spectroscopy (PALS). The mechanism for ethanol molecules diffusing in the cross-linked polymer film was proposed.
