Objective Perform the following procedures (1 and 2) in parallel for the start to the synthesis of cross-linked polymer and cross-linked polymer-clay films. Description Description of todays protocol taken from 08-27-14 link to prepared the starting materials from Matt Hartings Notebook Polymer-Clay Films Add 7mL of water to 1.0023g of 22,000MW polyvinyl alcohol and 0.1102g of sodium montmorillonite in a glass vial Stir the solution with constant heating at 75C until the polymer is dissolved and the clay is dispersed (~15 minutes) Cool the solution to room temperature Add 0.5mL 0.8 wt% glutaraldehyde. NOTE: Perform step 4 in the hood Stir for an additional 3 minutes to ensure homogeneity Pour solution into a teflon dish to dry until the next class Polymer Films Add 7mL of water to 1.006g of 22,000MW polyvinyl alcohol in a glass vial Stir the solution with constant heating at 75C until the polymer is dissolved (~15 minutes) Cool the solution to room temperature Add 0.5mL 0.8 wt% glutaraldehyde. NOTE: Perform step 4 in the hood Stir for an additional 3 minutes to ensure homogeneity Pour solution into a teflon dish to dry until the next class Data Add data and results here...
