Tasks for February 4th
Using amine to epoxy ratio of 1:1 in equivalent weights (equivalent weight of epoxy 188-192g/mol, Jeffamine D-400 Amine 104 g/mol);
Note: the first two epoxy/TiO2 trials were heated to 85°C for 5 min and allowed to cool down to 50°C for the next 10 min. These temperatures were arbitrary, however, after DSC analysis it was determined that curing begins to occur at ~60°C and attains a maximum efficiency of curing at 118.5°C.
