N2 - Acrylonitrile butadiene rubber (NBR) compounds with a hybrid filler system, containing carbon black (CB) and a surface functionalized talc filler with a platelet-like structure, were investigated. The effect of the loading of the high aspect ratio filler (0-80 phr) on mechanical, thermomechanical, morphological, and hydrogen gas barrier properties were evaluated. With increasing amount of the talc filler, the NBR grades exhibit an increase in modulus, whereas the glass transition temperature remains unaffected. The platelet-shaped fillers show a good distribution and orientation in the rubber matrix and hence create obstacles for permeating gas molecules. The coefficients related to hydrogen transport properties in the material, solubility, diffusivity, and permeability, all exhibit a decrease with increasing loading of the high aspect ratio filler, leading to overall enhanced gas barrier properties of the rubber materials.
