Objective
- Complete the film synthesis from Wednesday
- Start new film synthesis of both polymer films and polymer-clay films.
- Make all Malachite green solutions
Protocol
- Complete Film synthesis from Wednesday August, 27th
- Warm 150mL of Sodium Sulfate Solution at 80C for 15 minutes
- Place film in Sodium Sulfate Solution at 80C for 1 hour with gentle stirring
- Warm 150mL of 1% HCl at 80C for 15 minutes
- Place film in 1% HCl Solution (see below for details) at 80C for 30 minutes with gentle stirring
- Place film in Sodium Bicarbonate Solution for 15 minutes at room temperature with gentle stirring
- Starting new film Synthesis
follow the same procedure as Wednesday August 27th

Solution Preparation
Complete film synthesis
- 0.2M Sodium Sulfate Solution
- I dissolved 22.034g of anhydrous Na2SO4 in 1000mL of water
- I added 100mL of concentrated H2SO4 to this solution
- This solution will be used to enable the reaction between polyvinyl alcohol and glutaraldehyde in order to cross link the polymer film
- 1% wt. HCl Solution
- I added 10mL of concentrated HCl to 985mL of water
- This solution will be used to enable the reaction between polyvinyl alcohol and glutaraldehyde in order to cross link the polymer film
- 0.2M Sodium Bicarbonate Solution
- I dissolved 17.042g of NaHCO3 in 1000mL of water
- This solution will be used to neutralize the acid in your films
