    <title language="eng">Effect of high-pressure hydrogen environment on the physical and mechanical properties of elastomers</title>
    <abstract language="eng">This study presents the influence of high-pressure hydrogen environment on the physical and mechanical properties of two types of cross-linked hydrogenated acrylonitrile butadiene rubbers. Based on the CSA/ANSI standard, static exposures in hydrogen experiments were performed up to 100 MPa at 120 °C. Characterization before and after exposure was conducted by means of density and hardness measurements, dynamic mechanical analysis (DMA), tensile tests, compression set, FT-IR and AFM analyses to assess effects after decompression. While the effect of high-pressure exposure is significant immediately after exposure, most of the physical and mechanical properties recover after 48 hours. FT-IR, AFM, SEM and compression set results indicate, however, permanent effects.</abstract>

    <title language="eng">Effect of high-pressure hydrogen environment on the physical and mechanical properties of different kinds of carbon black filled elastomers.</title>
    <abstract language="eng">As the transition towards the usage of renewable energy is getting urgent, the fluctuations of clean energy production require efficient storage alternatives. Hydrogen offers not only the possibility of energy storage but also, acts as an energy carrier. It is then important to study the effect of highly pressurized hydrogen atmosphere on the materials destinated for its storage and transport, in order to assure the reliable performance of the sealing materials containing hydrogen. In this study, a set of carbon black (CB) filled rubbers comprising hydrogenated acrylonitrile butadiene rubber (HNBR), acrylonitrile butadiene rubber (NBR) and ethylene propylene diene monomer rubber (EPDM) was tested under high pressure hydrogen atmosphere (1000 bar) and at different temperature conditions: 120°C for HNBR, room temperature and 85°C for NBR and EPDM. The influence of hydrogen on the materials properties was measured after 7 days of exposure under hydrogen and evaluated again after 48h. Density and volume change, as well as hardness, tensile tests, compression set, dynamic mechanical measurements and infrared spectroscopy evaluations were conducted to estimate the impact of high-pressure hydrogen on the rubber grades. Our study reveals, an effect on the physical and mechanical properties, possibly related to small changes in the matrix-filler interaction after the hydrogen exposure. All materials, however, show a trend to recover most of their properties 48h after hydrogen exposure.</abstract>
