Part A

  • 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.
  • 100,000 PVOH
  • 22,000 PVOH
  • 100,000 PVOH with a drop of HCL
  • 22,000 PVOH with H3Po4 and maleic acid
  • 22,000 PVOH with H3Po4 with H3PO4.
