Abstract:
Electrochemical sensing techniques are the advance techniques for the detection of water
contamination. Conducting materials in electro-chemical sensors are based on graphene
or carbon nano tubes (CNT) substrate mostly. Resent literature has documented the
hazardous effects of graphene and carbon nanotubes (CNT). Moreover, use of these
substrates enhances the cost of the sensor to a larger extend. Currently environment
friendly and sustainable natural materials are replacing the toxic materials for the
development of electro-chemical sensors. In this view current research work aims at the
synthesis of conducting composite by incorporating eco-friendly and abundantly
available natural material i.e. cellulose as a substrate. Initially nano-cellulose was
synthesized and subsequently it was functionalized with polyaniline and nano metal
oxides to enhance the conductivity. The synthesized nanocomposite was characterized
through FTIR analysis. Conductance of the synthesized materials was checked and IV
graphs were plotted. The results showed that conductance of nano composite was
increased subsequently by the addition of different metals to NC/PANI composite.
