Confirmation and Quantification of Linear Low-Density Polyethylene (LLDPE) and Maleated Linear Low-Density Polyethylene (LLDPE-G-Ma) Infused with Nanoclay in Supercritical Carbon Dioxide
Nanoclay fillers have the ability to enhance the thermo-mechanical, barrier and flame resistant properties of Linear Low-Density Polyethylene (LLDPE). In order to achieve a maximum level of property enhancement, however, the difficulties with the use of nanoclay fillers lie in the completeness of exfoliation and also in the extent of dispersion into a polymer matrix. One method employed to successfully disperse powders into polymers that is both inexpensive and deemed environmentally friendly is supercritical carbon dioxide processing. Besides being a means of effective dispersion, it is conceivable that supercritical carbon dioxide may be used to exfoliate nanoclays, which can further enhance the resultant nanocomposite properties. With supercritical carbon dioxide processing, Cloisite 93A was infused into LLDPE and Maleated LLDPE (LLDPE-g-MA). The infusion of Cloisite 93A was confirmed by XRD and FTIR analysis. In addition, XRD analysis suggests that clay intercalation was achieved for select runs. Further, FTIR analysis was used to determine the amount of nanoclay infused into the polymer.
