Abstract
Growing interests in the development of advanced functional materials from renewable resources due to the depleting petroleum resources, increasing costs, and associated hazards reflect global requirement for increased sustainability. Cardanol [Col] is an agro by- product of the cashew nut industry. It is cost effective, nontoxic, biodegradable and an abundantly available renewable resource. In the present study, we report the development of nanostructured coordination polymer [CP] self- standing transparent films from Col (as an organic linker or bridging- ligand) and Mn(II) 'd(5)' and Co(II) 'd(7)' divalent metal ions (as metal nodes) by a solid- state in situ method. The resulting CP films showed nanoporous morphology, amorphous behaviour, good thermal stability up to 260-300 degrees C, moderate antibacterial activity against Staphylococcus aureus (MTCC 902), Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (MTCC 2453) and also good anti- biofilm activity.
