摘要: Abstract Green nanocomposites consisting of bio-based poly(dibutyl itaconate- ter -isoprene- -4-vinylpyridine) (PDBIIVP) elastomers with different 4-vinylpyridine (4-VP) contents and natural layered silicate montmorillonite (MMT) were prepared by a green latex co-coagulation method. The effects the pyridine groups on interfacial interaction, morphology, performance investigated. Ionic bonding interfaces, which confirmed X-ray photoelectron spectroscopy, introduced to through electrostatic attraction between protonated modified electronegative MMT during PDBIIVP aqueous suspension hydrochloric acid. dispersion interaction improved remarkably, as demonstrated diffraction, transmission electron microscopy, rubber process analyzer (RPA) results swelling tests. mechanical gas barrier properties markedly increasing 4-VP content. For 7.0 wt% 4-VP, addition 10 phr increased tensile strength 730% reduced permeability 71%.
