Study on the Properties of LDPE/POE/Zeolite Molecular Sieves Composite Film
By means of melt blending process in a co-rotating twin screw extruder with two-step process, the low density polyethylene (LDPE)/ethylene octene copolymer (POE)/zeolite molecular sieves (ZMS) composites were prepared. The influence of ZMS on the crystallinity, mechanical properties and permeability was investigated by differential scanning calorimetry(DSC), universal testing machine and permeability tester, respectively. The results showed that the addition of ZMS made the crystallinity of composite film decreased and the growth rate of crystal nucleus promoted. As the content of ZMS rose, the mechanical properties of composite film decreased, while the CO2, O2 permeability and the moisture permeability increased.
