Spin-contrast-variation small-angle neutron scattering study of fully and partially swollen silica-filled rubber

Noda, Yohei*; Kumada, Takayuki ; 7 of others*

We elucidated the polymer adsorption layer structure in filler-rubber systems by using spin-contrast-variation small-angle neutron scattering on partially and fully swollen filler rubber samples with and without a silane coupling agent. The difference in polymer volume fraction between the polymer adsorption layer and the outside matrix was very small in less swollen states but significant in the fully swollen state.
