		+	<u>PVOH/Glutaraldehyde Film</u>
		+
		+	# 0.5 g PVOH was dissolved in 5 mL water on a heated hot plate.
		+	# Once dissolved, 0.8% wt Glutaraldehyde solution (1 mL) was added.
		+	# The gel was then poured into a plastic dish and was allowed to evaporate over the weekend.
		+
		+
		+	<u>100% CEC Clay Preparation</u>
		+
		+	* HdPh3P+ = (1-Hexadecyl)triphenylphosphonium Bromide
		+
		+	# 0.92 meqv/g surfactant (HdPh3P+, 1.06 g) was added to 2 g of Na-MT in a solution of 25 mL ethanol and 25 mL water.
		+	# The clay was left for a week to stir
		+
		+
		+	<u>50% CEC Clay Preparation</u>
		+
		+	# Half as much surfactant as was used for the 100% CEC clay (0.53 g) was added to 2 g of Na-MT in a solution of 25 mL ethanol and 25 mL water.
		+	# The clay was left to stir for a week.
