You pretty much have it.  You just need to force Mathematica to use
the local variable from the Manipulate.  One easy way is to use
ReplaceAll to rename VolumeFraction to a temporary variable
(VolumeFraction2):

Manipulate[
 LogLinearPlot[
  Evaluate[
   Re[MeasuredCMF] /. {VolumeFraction -> VolumeFraction2}], {f, 10^5,
   10^9}],
 {{VolumeFraction2, 0.2}, 0.1, 0.5}]

Good luck!
