Objective

Creating Thin Polymer Films of PVOH

Description

1) 22,000 MW PVOH: (a) 0.5 g PVOH was mixed with 3 mL of milli Q water, stirred, and heated to 80 degree Celsius. The solution was placed in a small container up to 48 hrs to allow the thin film formation to occur.

(b) 1.01 g of PVOH was mixed with 5 ml of milli Q water and the resulting solution was heated to 80 deg Celsius, until dissolved. The resulting solution was stored for 48 hrs to allow the thin film production to occur.

2) 100, 000 MW PVOH (a) 0.5 g of PVOH was mixed with 5 mL of milliQ water and the resulting solution was heated up to 80 deg Celsius, until dissolved.

(b) 1.0 g of PVOH was added in 8 mL of milliQ water and the solution was heated up to 15 mins.

Notes

0.5 g PVOH solution was unable to dissolve initially, so we had to add extra 2 ml of water to make it dissolve. 1.0 g of PVOH solution was unable to dissolve, and we had to add additional 3 ml of water to make it dissolve.
