==PVOH Film Preparations==
'''Prepared PVOH films in water:'''
* In 10mL beaker, weigh out ~ 0.5 grams PVOH (MW 130,000)
'''(Actual Mass = 0.4934g)'''
* Then, using a graduated cylinder add ~ 3 mL H2O to the beaker
* In another 10mL beaker, weigh out ~ 1.0 gram PVOH (MW 130,000)
'''(Actual Mass = 0.9965g)'''
* Then, using a graduated cylinder add ~ 5 mL H2O to the beaker

'''Standard PVOH Film Protocol:'''
* After adding and combining PVOH (MW 130,000) in small beakers with H2O, add stir bars and prepare to stir solution.
* On hot plate, stir and heat both beaker solutions at 70-80°C for ~ 12 min or until PVOH dissolves.
* Once PVOH solids thoroughly dissolve in solution, pour each solution in a Teflon dish to sit, cool, and dry in a fume hood for ~ 1 day.

'''Notes:'''
* An additional 2-3 mL H2O was added to each solution to aid the dissolving of the PVOH
* Heat was reduced when solutions began to boil too rapidly
* While transferring solutions to Teflon dishes, loss of sample within the small beakers (sample loss = incomplete sample transfer)
