Feb 4- Coatings and DSC
Objectives
- Put the aluminum plate in the oven on temperature 85C for two hours
- Increase temperature to 135C for two more hours
- Repeat the synthesis from Friday, 30th of January, 2015
- Start a new synthesis, without the titanium dioxide
- Analyze DSC Data
TiO2/Epoxy Film Synthesis
- measure 3.03450 and 3.04546 g of JD-400
- add 5.52087 and 5.86469 g of the epoxy
- add 0.84646 and 0.86432 g of TiO2
- let stir for 5 minutes with temperature of 85C
- reduce the temperature to 60C for another 10 minutes.
- transport the mixture into an aluminum dish
- Let it sit in room temperature till next lab section.
Epoxy without TiO2 present Synthesis
- measure 3.03840, and 3.07631 g of JD-400
- add 5.53123 and 5.65516 g of the epoxy
- let stir for 5 minutes with temperature of 85C
- reduce the temperature to 60C for another 10 minutes.
- transport the mixture into an aluminum dish
- Let it sit in room temperature till next lab section.
DSC Results
- Figure 1. DSC results for Ti)2 coating before curing.
- The Differential Scanning Calorimetry (DSC)analysis gave us the following information
- Curing for TiO2 coatings begins at 66.51 degrees Celsius, the upper limit was 74.53 and the lower limit was 58.49 degrees Celsius
- The maximum curing temperature was at 120 degrees Celsius
- The system takes an average of 196.45 J/g of energy, the upper limit was 201.6 and the lower limit was 191.3
