- Dynamic Mechanical Analyzer was used to find out the stiffness and flexibility of each films.(width 5.3 mm)
- DMA of 22,000 film was measured.(without crosslinking)
- DMA of 100,000 film wihout cross-linking will be done next week.
- Following films were cross-linking(kept at 120C for 90min) for DMA.
