A direct method is presented for measuring the shear modulus of gels. The method is based on torsional oscillations of a gel sample. Only small distortions are introduced, ensuring linearity of response. The forces involved do not have to be measured directly; they are inferred from the oscillation
The swelling and mechanical properties of thermally sensitive Nisopropylacrylamide (NIPA) hydrogels containing 0-35 mM sodium acrylate comonomer have been investigated at room temperature. The swelling medium is an aqueous solution with an NaCl concentration varying from 0 to 3.0 M. As the NaCl conc
