- Crosslink the prepared glutaraldehyde film
- Run DSC on 8 films
- Run FTIR
- Repeat the crosslink of glutaraldehyde film
General Protocol 1(klare and Liz):
- Allow the glutaraldehyde PVOH film to completely air dry
- Prepare a solution of 100mL H2O, 2mL concentrated H2SO4, and 20g Na2SO4 in a 150mL beaker. Place stir bar in beaker and a Buchner funnel top over the stir bar
- Heat the prepared solution to 70°C(on hot plate turn temperature to 160°C)
- Place film in solution for 1 hour.(Make sure the temperature remains at 70°C)
- Prepare 100mL 1% aqueous HCl solution. Heat solution to 70°C
- Remove film from the solution and rinse with deionized H2O
- Place stir bar in 1% HCl solution and a Buchner funnel top over of the stir bar. Add the PVOH film to the solution
- Allow film to remain in 1% HCl solution for 30 minutes.(Be sure to keep a constant 70°C)
- Prepare 0.2M sodium bicarbonate solution
- After 30 minutes, remove film from 1% HCl solution and place in 0.2M sodium bicarbonate solution for ~15minutes
- Remove film from dilute sodium bicarbonate solution with tweezers. Rinse with deionized H2O and dry film on paper towel(dabbing gently).
- Weigh PVOH film. Record mass
General Protocol 2 (Noah):
- Repeat Glutaraldehyde film prep
- make 2nd glutaradehyde film film, except and replace 10% PVOH with PDMS
- Prepare 1 L glutaraldehyde solutions
- prepare 500ml 20ppm SO42- as CuSO4
- prepare 500ml 20ppm SO42- as Na2SO4
- dry clays
- Add data and results here...
