Objectives

  • Cure films from last lab period into the ovens
  • Characterize swelling of epoxy films
  • Prepare new films for PXRD analysis
  • Autoclave broth solution

Measurement of swelling in epoxy film

  • The film made on February 4 was cut into pieces, weighed and measured for thickness, then placed in water until the next lab period
  • Measurements were as follows:
Section Initial thickness (mm) Initial weight (g) Final thickness (mm) Final weight (g) % difference in thickness % increase in weights
1 2.17 2.22551 2.30 2.24013 5.99 0.6569
2 1.78 2.23953 1.78 2.25681 0 0.7716
3 1.65 0.93694 1.66 0.94787 0.61 1.1656
4 2.32 2.30817 2.29 2.32841 -1.29 0.8769


LB Broth Media

  • measure 80 mL of water
  • add 2 g of LB Broth
  • autoclave and sterilize in 121C for 60 minutes, and leave for another hour until the pressure drops back to atmosphere pressure
