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
