A unique feature of molecular iodine by far, is its ability to bind to polymeric 
materials. A plethora of natural and synthetic polymers develop complexes when treated 
with molecular iodine, or with a mixture of molecular iodine and potassium iodide. Many 
unexpected findings have been encountered upon complexation of iodine and the polymer 
skeleton, including the color formation, the polymer morphology changes, the complexation 
sites or regions, the biological activity, and the electrical conductivity enhancement of the ...
