Tasks for September 26

  • To complete Wednesday's film synthesis
  • To begin new film synthesis

Completing film synthesis

  • Continued from September 24
  • Soaked in sodium sulfate for 1h, put into 0.1% HCl for 30 min, then sodium bicarbonate solution for a further 15 min.

Preparation of 10% wt new exfoliated clay films

  • 1.0114 g 22,000 PVA, 0.1107 g of of exfoliated tributylhexadecylphosphonium bromide (THP Br) and 7 mL of distilled water were used to make up a 10% wt PVA-exfoliated THP Br film. Note this clay was prepared by Michael's group.
  • 1.0290 g 22,000 PVA, 0.1105 g of exfoliated 1-hexadecyltriphenylphosphonium bromide and 7 mL of distilled water were used to make up a 10% wt PVA-exfoliated THP Br film. This clay was previously prepared by Eleni's group.
