Title: Structure of polymer solutions and gels containing fillers
Abstract: Small angle neutron scattering (SANS) gives information on the structure of binary systems such as polymer solutions or swollen networks. By using mixtures of protonated and deuterated solvent the neutron scattering contrast can be varied, thus allowing ternary systems to be investigated. Here we describe SANS measurements in poly(dimethyl siloxane) (PDMS) solutions and gels containing fumed silica fillers with different surface treatments. Three different partial structure factors of the filled polymer samples can be distinguished, Spp(q), Spf(q) and Sff(q), where the subscripts p and f refer to polymer and filler. The structure factor of the polymer Spp(q) resembles that of star polymers. The distribution of the polymer in the network depends on the surface treatment.
