A novel electrically active, water soluble gum acacia-polyaniline (GA-PANI) hybrid was synthesized using ceric ammonium nitrate as initiator in acidic medium. The representative hybrid material was characterized using UV-visible, FTIR and SEM taking polyaniline as reference. The composition of aniline to gum acacia was tailored to optimize possible cross-linking in side the hybrid. The hybrid material exhibited pH switching electrical conductivity, which was decreased with increasing pH of the material. I-V characteristics and acid-base sensitivity of the hybrid material were extensively investigated in order to find out its electronic behavior during current flow.
