Preparation and characterization of low density polyethylene nanocomposites

with modified montmorillonite clay (in English)

Polimery 2009, No 7/8, 536


Summary

Organically modified montmorillonite clay (OMC) and its iron complex (OMC-Fe) were prepared using 1-acetylpyridinium chloride salicylhydrazone. Low density polyethylene (PE-LD) was compounded with either OMC or OMC-Fe (in amount of 3 or 7 wt. %) using ultrasonic radiation. The morphology of polyethylene composites was characterized by atomic force microscopy (AFM). The thermal stability and flammability properties of polyethylene composites were evaluated using thermogravimetric analysis and cone calorimetry, respectively. The resultant composites exhibited improved flammability relative to the pure polyethylene.


Key words: low density polyethylene, modified montmorillonite clay, ultrasonication, atomic force microscopy, cone calorimeter
