Abstract: Naturally occurring biopolymer - gum arabica, which is obtained from acacia tree, is being used for its excellent medicinal properties and has been found to be an ionic conductor. This biopolymer has been found to show high value of ionic conductivity after swelling and conductivity of the order of 10-3 S/cm at room temperature has been observed. Water uptake study shows this polymer to be superabsorbant in nature and has been found to reach a saturation level in about five hours. The conductivity of this biopolymer has been found to increase with swelling which suggests that the biopolymer releases ions during swelling which take part in the conduction process.
