Synthesis and Antibacterial Application of Nanosized Polyethylene oxide - Iodine Complex by Solid - Vapor Reaction

Authors(4) :-Ishwar Das, Avinash Kumar Pandey, Shobhna Dorthy Fredrick, Abhishek Kumar Mishra

An eco-friendly reaction between polyethylene oxide (PEO) and iodine vapor has been studied on microslide. Growth kinetics was studied by measuring an increase in weight of the material as a function of time and found to increase non- linearly. Random distribution of iodine in the complex was observed by SEM-EDS studied. UV- visible absorption spectroscopy revealed a new peak at ~ 300 nm due to interaction of iodine with the polymer. Powder x-ray diffraction (XRD) patterns of the reactant and reactant product were compared. Both were found different. Crystallite size of the complex was calculated by using Debye Scherrer formula and found in the range 20-30 nm. The complex was thermally less stable than the reactant. An enhancement in the electrical conductivity was observed on complexation with iodine. SEM results also showed morphological change on complexation. TEM studies revealed the formation of nanosized (<10 nm) complex, in agreement with XRD results. Antibacterial application of the complex was investigated on blood agar containing gram negative bacteria E. coli and no bacterial growth was observed in its presence. It is found to be highly effective against the bacteria E. coli.
