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 titatnium dioxide Analyze DSC Data TiO2/Epoxy Film Synthesis measure 3.03450 g of JD-400 add 5.52087 g of the epoxy add 0.84646 g of TiO2 let stir for 5 minutes on a 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/No TiO2 present Synthesis measure 3.03840 g of JD-400 add 5.53123 g of the epoxy let stir for 5 minutes on a 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

More Epoxy and TiO2/Epoxy Synthesis

1. Measure the same proportions as early stated
2. Stir for 15-20 minutes on a temperature of 60C
3. Transport mixtures into aluminum dishes
4. Let them sit in room temperature
