Tasks for September 12 2014

To start preparing new films using exfoliated clay. <br.> Perform XRD measurement. <br.> Continue analysis of DSC and UVVis.<br.> To make new stock solutions of malachite green dye

Preparation of 10% PVA-exfoliated clay

Refer to Dr. Harting's Notebook for full details on the procedure

  • 2.7613 g of the 4% sodium montmorillonite were added to 1.0040 g of Polyvinyl Alcohol to make up a 10% PVA-exfoliated clay film
    • The calculations were as follows: 0.04[NaMT]=0.11
    • x= 2.75
  • 7 mL of water were added and the solution was heated to 75ºC with constant stirring
  • Solution was left to cool down to room temperature
  • Added 0.5 mL of 0.8 wt% glutaraldehyde.
  • Stirred for an additional 3 minutes to ensure homogeneity
  • Poured solution into a teflon dish to dry until the next class

Preparation of new malachite green solutions

  • A new 200 ppm MG solution was made by adding 40 mg of malachite green and making up to the mark with distilled water in a 200 mL volumetric flask.
    • (200 mg MG/1L)×0.2 L = 40 mg MG
