Previous research at the University of Tennessee found that incorporating chitosan in 25 m- to 44 m-thick polyethylene oxide (PEO) films may help the antibacterial properties of the films, decrease the tendency of PEO to crystallize, and enhance the puncture and tensile strength of the original films.
The presence of polyethylene oxide side chains caused them to exhibit solubility profiles similar to PEO base polymers (1) The solubility of these polymers decrease with increasing temperature.
Many polymers, including polyamide, polystyrene, polypropylene, polyethylene, polyethylene oxide, poly(ethylene terephthalate), liquid crystalline polymers, thermoplastic elastomers, rubber, polyurethane, polyimide, epoxies, and phenolics, have been investigated to incorporate with organoclay [1, 2].
