Synthesize 4 thin films using polyvinyl alcohols of different molecular weights
0.5 g of 22000g/mol PVOH was added to 3mL of water and stirred with heat until dissolved (~15 minutes). In addition to this 3 other solutions containing the following were prepared under the same procedure: 1.0g of 22000g/mol PVOH in 5mL H2O and 0.5g and 1.0g 100000g/mol PVOH in 3mL and 5mL H2O respectively. Once all four solutions were prepared, each was poured into a round dish where they were left to dry for 48 hours.
No data has been gathered thus far, however these films as well as other films prepared in a similar manner will be later analyzed using several analytical methods (IR spectroscopy, Differential Scanning Calorimetry, X-Ray diffraction etc.)
This area is for any observations or conclusions that you would like to note.
