ObjectiveTo conduct Differential Scanning Calorimetry, to complete the cross-linking reactions conducted last week, and to finish evaporating water from the two films made on Wednesday.
DescriptionDifferential Scanning Calorimetry
0.2 g of Films 2,4,5,6, and 7 (See below for list of films) were placed into an oven set to 90°C for 90 minutes.
DataDifferential Scanning Calorimetry Trial 1 (Film 1) - mass of pan and lid = 0.05002 g, mass of pan and lid with material = 0.05285 g Trial 2 (Film 3) - mass of pan and lid = 0.04993 g, mass of pan and lid with material = 0.05317 g Trial 3 (Film 5) - mass of pan and lid = 0.04880 g, mass of pan and lid with material = 0.05132 g
After 90 minutes in the oven:
