Abstract
Development of new greener material for conducting paper is sought for applications such as security paper, actuators, and anti-static packaging. In the present work a conducting paper/conducting polymer composite is prepared using bacterial cellulose and polyaniline. It is required that these materials possess high conductivity, low density and good mechanical integrity. This work aims to produce bacterial nan cellulose (BC) -polyaniline (PANI) nanocomposites by in situ polymerization. The advantages of using BC over filter paper are evident from the results in this report because of its ultrafine network structure, sufficient porosity, high purity and crystallinity, good mechanical properties, water holding capability and low environmental impact. Strategies to produce these composites from BC membranes and nanowhiskers have been reported. The BC/PANI composites thus formed are expected to possess good electrical conductivity and capacitance, in addition to excellent mechanical properties and flexibility. In this work, synthesis of polyaniline has been optimized and preliminary results on BC-PANI composites have been shown.
