The method of preparation of Gelatin/poly (aniline) composite films has been discussed. Gelatin was cross linked with glyoxal (Glox) in aqueous medium. The composite film was prepared by in-situ polymerization of Aniline within the Gelatin film matrix. The films so prepared have been characterized with XRD, tensile testing and conductivity measurements. The variation in mechanical/electrical properties of Gelatin/poly(aniline) composite films with varying concentration of aniline have been investigated. It was observed that the electrical conductivity of the films increase appreciably with the concentration of aniline in the film. In addition, the tensile strength of the films was also found to increase with aniline concentration. The results from XRD, conductivity test and tensile testing were correlated. A stronger material having added advantage of conductivity has been reported. Copyright © 2017 VBRI Press.
