Aug 27- Synthesis of films Group Members Andrew Farag Sr (Undergrad) and Michael Bible Jr (Undergrad) Group Name : AMT Objective Starting synthesis for both polymer and polymer-clay films Description Starting materials were prepared by Dr. Hartings according to his lab notebook. Perform the following procedures (A and B) in parallel for the start to the synthesis of cross-linked polymer and cross-linked polymer-clay films. This procedure is repeated weekly and will be refered to as the 'Synthesis of flims procedure'. (A) Polymer-Clay Films 1.Add 7mL of water to 1.0041 g of 22,000MW polyvinyl alcohol and 0.11g of sodium montmorillonite in a glass vial 2.Stir the solution with constant heating at 75C until the polymer is dissolved and the clay is dispersed (~15 minutes) 3.Cool the solution to room temperature 4.Add 0.5mL 0.8 wt% glutaraldehyde. (NOTE: Perform step 4 in the hood) 5.Stir for an additional 3 minutes to ensure homogeneity 6.Pour solution into a teflon dish to dry until the next class (B) Polymer Films 1.Add 7mL of water to 1.0030 g of 22,000MW polyvinyl alcohol in a glass vial 2.Stir the solution with constant heating at 75C until the polymer is dissolved (~15 minutes) 3.Cool the solution to room temperature 4.Add 0.5mL 0.8 wt% glutaraldehyde. (NOTE: Perform step 4 in the hood ) 5.Stir for an additional 3 minutes to ensure homogeneity 6.Pour solution into a teflon dish to dry until the next class (Description from Dr. Hartings lab notebook Dr. Hartings Notes and Calculations Polymer - Clay film weights 1.0041 g polyvinyl alcohol 0.1100 g sodium montmorillonite Polymer Flim weight 1.0030g polyvinyl alcohol
