The swelling equilibrium under a uniform magnetic field

6 The swelling equilibrium under a uniform magnetic field 

A comprehensive study of the effects of a uniform field on swelling behaviour is stiU lacking. It is therefore a major objective of this work to build a 

17 Elastodynamic response of a ferrogel at different frequencies of sine wave modulation. (Top) Photographs about a ferrogel with elastodynamic response. Solid line represents the modulated current, dotted line corresponds to the elastic response.The frequency, f, is indicated on the figure. 

These quantities can be derived from free energy of the elastic and mixing interactions. 

18 Components of the chemical potential of the swelling agent as a function of volume fraction of the polymer. For the calculation 2h = 0.3 and = 2.15 10 was used.
