Description

Part 1: Prepare a film for dye attachment

  • 0.5 g PVOH 2200
  • 7 ml of sodium bicarbonate
  • dissolve the PVOH with sodium bicarbonate.
  • let the solution cool down
  • add 1 mg of dye.stir it well.
  • pour in to a teflon.let it dry


Part 2: Measure the dry mass of cross-linked gluteraldehyde film made on 14/11/2012 and cross-linked on 16/11/2012

dry mass:0.6707g

Data
