Characterization of ZnO - Biopolymer Nano Composites

Arnab Gangopadhyay and A. Sarkar

In this work ZnO nano clusters were grown in biopolymer background. Attempt has made to control the nano-cluster size by the in situ chemical sol-gel process. The dc volt-ampere characteristics of the developed ZnO nano composites which were prepared under different conditions were measured. XRD and optical absorption of the material were also studied to get information on grain size. The work indicated a possible new characterization technique by the use of the dc I-V characteristic which perhaps contains information about cluster size of the nano composites.
