The Volatile Organic Substance Permeability of Nano- and Micro-Rubber Composites

摘要

Due to the statutory requirements for zero emission vehicle (ZEV) and for technical reasons, the automotive industry is increasingly interested in achieving extremely high permeation resistance in the case of fuel and fluid system elastomer components[5]. The objective of this work is to contribute to the development of high permeation resistance elastomeric materials. In this context, the influence of parameters such as polymer type, crosslinking density, filler, filler content and distribution are all to be examined. Dynamic methods for measuring volatile organic substance (e.g. fuel components) permeation with high sensitivity/selectivity in the case of material mixtures and good reproducibility will be developed with theoretical aspects. The incorporation of micro- and nano-particles with polymeric materials is a traditional way to improve the properties of a polymer matrix [6]. A special filler, micro glass flake, is used in this study. A specific series of hydrogenated acrylonitrile-butadiene (HNBR) rubber with different ACN contents and XLD is investigated. The time lag t, diffusion coefficient D, permeation rate P, and equilibrium value of permeation have been obtained during this study.
