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. Heated at approx. 80ºC with gentle stirring until all crystals were dissolved Allowed to cool down to room temeprature Added 0.8 wt% 0.5 mL glutaraldehyde under hood Stirred for 3 min to ensure homogeneity Poured into teflon dish and allowed to dry
