Effect of octadecylamine modified graphene on thermal stability, mechanical properties and gas barrier properties of brominated butyl rubber

Effect of octadecylamine modified graphene on thermal stability, mechanical properties and gas... Abstract Graphene oxide (GO) was modified with octadecylamine (ODA) in ethyl alcohol solution to obtain GO-ODA hybrid. GO-ODA/brominated butyl rubber (BIIR) composites were obtained by solution mixing, in which GO-ODA was well dispersed in nano-sized as confirmed by transmission electron microscope images. The GO-ODA/BIIR composites had much better mechanical properties than BIIR. The stress at 300% extension of BIIR increased 230% after the addition of 10 phr GO-ODA. The improved mechanical properties benefited from the strong interaction between GO-ODA and BIIR. The heat resistance of GO-ODA/BIIR composites was improved with increasing GO-ODA loading. GO-ODA/BIIR nanocomposites had better gas barrier properties than BIIR, and the gas transmission rate of GO-ODA/BIIR (10/100) nanocomposite was only 21.2% of that of BIIR. The improved mechanical, heat resistance and gas barrier properties bring BIIR the potential to be used in a wider range of application areas. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Macromolecular Research" Springer Journals

Abstract

Abstract Graphene oxide (GO) was modified with octadecylamine (ODA) in ethyl alcohol solution to obtain GO-ODA hybrid. GO-ODA/brominated butyl rubber (BIIR) composites were obtained by solution mixing, in which GO-ODA was well dispersed in nano-sized as confirmed by transmission electron microscope images. The GO-ODA/BIIR composites had much better mechanical properties than BIIR. The stress at 300% extension of BIIR increased 230% after the addition of 10 phr GO-ODA. The improved mechanical properties benefited from the strong interaction between GO-ODA and BIIR. The heat resistance of GO-ODA/BIIR composites was improved with increasing GO-ODA loading. GO-ODA/BIIR nanocomposites had better gas barrier properties than BIIR, and the gas transmission rate of GO-ODA/BIIR (10/100) nanocomposite was only 21.2% of that of BIIR. The improved mechanical, heat resistance and gas barrier properties bring BIIR the potential to be used in a wider range of application areas.
