Viscoelastic characterisation of calcium alginate gels intended for wound healing
K Ofori-Kwakye, GP Martin
Abstract
Calcium alginate gels were prepared and characterised in terms of their viscoelastic properties. For all the gel samples, the storage or elastic modulus (G') increased with increase in frequency of oscillation of the samples whilst the dynamic viscosity (h') decreased with increase in frequency of oscillation. An increase in the concentration of Ca2+ caused an increase in the elastic modulus of the gels. The G' of gels prepared with different grades of alginate increased in the order of increasing viscosities of the alginate grades (SOBALG PH 160
