Abstract :
The current research work deals with the investigation of polyaniline nanoparticles as the substrate of the molecular imprinted polymer. Molecular imprinting is an interesting way to emulate the natural molecular identification that will be realized by preparing artificial identification sites with preset election for different target analytes. In this method, the target analyte acts as a template and will be connected to functional monomers through covalent or non-covalent bonding during the process of polymerization. Among all the conducting polymers, polyaniline is known for its unique electrical conductivity which can be controlled by the degree of oxidation of the main chain and protonation. Also, it shows different color changes with respect to the degree of oxidation and the surrounding pH. The results and investigations conducted in this study suggest that molecular imprinted polymers can be successfully developed by using aniline as monomer and preparation of linear polymer, and by using method of conductometry, the presence or absence of imprinted substances can be observed in the polymer according to the changes in conductivity caused by these phenomena.
