Feb 11- Swelling continued
Objectives
- synthesize more films
- Cure films from last lab
- swelling test for epoxy film
- Get approval on the bacteria test procedure
- Data
Swelling test on TiO2/Epoxy Test
- Weigh and measure thickness for film sections
Table 1. Thickness and Weighs of Film Sections Before and After Swelling Test
Swelling test epoxy only
- 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
