Abstract

The microstructure of Stomaflex Crème (SC) and of magnetic elastomers obtained by the addition of ferrofluid (FF) to the SC polymer matrix has been investigated by small-angle neutron scattering (SANS) within the q-interval . Two kinds of elastomers were analyzed: polymerized with and without magnetic field at mass concentration of magnetic particles. SANS data from SC exhibit a behavior, while for magnetic elastomers, two power-laws ( for low q and for high q) and one exponential regime are observed. The fractal dimensions for SC and magnetic elastomers, and radius of gyration of magnetic particles were quantified by approximating SANS data with a surface fractal model and unified exponential/power-law approach, respectively.
