Sept 26 - Creation of ion exchanged films Group Members Andrew Farag Sr (Undergrad) and Michael Bible Jr (Undergrad) Group Name : AMT Objective Create duplicate films from the ion exchanged clays The films were created using the procedure from 9/24 Finish processing the clays from 9/24/2014 Completing film synthesis The ion exchanged clays were processed using the procedure from 8/29/2014 Warm 150mL of Sodium Sulfate Solution (see below for details) at 80C for 15 minutes Place film in Sodium Sulfate Solution (see below for details) at 80C for 1 hour with gentle stirring Warm 150mL of 1% HCl at 80C for 15 minutes Place film in 1% HCl Solution (see below for details) at 80C for 30 minutes with gentle stirring Place film in Sodium Bicarbonate Solution for 15 minutes at room temperature with gentle stirring Ion Exchanged Films The PVA with (1-hexadecyl) triphenylphosphonium bromide film from Eleni's group looked homogeneous, with a light brown color. Below is a picture of the PVA with tributylhexadecylphosphonium bromide made by my group. In this case the clay was not evenly dispersed.
