Sept 12 - Exfoliated Clay
ObjectiveStart preparing new films using exfoliated clay. Perform XRD measurement. Continue analysis of DSC and UVVis. Description
(Description from Dr. Hartings lab notebook Dr. Hartings) CalculationsA 10% clay has 1g of PVA and should have .11g of exfoliated clay. .11g of clay = (4% solution)x = (0.04)x x = 2.75g of exfoliated clay solution Actual mass of solution used was 2.5387g. NotesNew Malachite Green/PVA-Film Experiment After the last experiment in which PVA-films with and without clay were placed in solutions of malachite green with various concentrations, it was noticed that some of the malachite green was absorbed by the glass vials in which the experiment was performed. Therefore an additional experiment was set up with the varying concentrations of MG in the glass vials only, no films were added, so that a calculation can be made of how much MG is absorbed into the glass vials.
