Structure of porous Vycor glass

Small-angle neutron scattering experiments investigating the structure of porous Vycor glass are reported. The long-wave-length behavior (0.004 A/sup -1/less than or equal toqless than or equal to0.025 A/sup -1/) of the measured structure factor S(q) is in good agreement with Cahn's prediction for spinodal decomposition. The high-q data do not conclusively establish whether the internal surfaces are fractally rough over the length scales probed. Experiments on Vycor contrasted with protonated and deuterated cyclohexane reveal local composition gradients within the glass.
