摘要：

The structure of layers of poly(dimethylsiloxane) terminally grafted on silica has been studied by small angle neutron scattering. We have observed the influence of the polymer molecular weight, the grafting density and the solvent quality. At a high grafting density, in good and in bad solvents, the chains are stretched and the thickness of the layers is proportional to the polymer mass. In a good solvent the inner structure of the layers is similar to that of a semi-dilute solution of free polymer at the same local concentration, in agreement with the description of Alexander.
