| Abstract: |
| Melt mixing was used to prepare polypropylene/vermiculite nanocomposites. Their crystallization properties, mechanical properties, resistance performance of oxygen and damp, and friction performance were tested. The experimental results showed that nanoscale dispersion of polypropylene/vermiculite nanocomposites with 1% vermiculite is good. The oxygen resistance performance is vastly improved. The oxygen permeability is reduced by 12.89% compared with polypropylene without vermiculite. |
| Key words: vermiculite polypropylene nanocomposites oxygen permeability |
