Hi, I am encapsulating essential oils in silica mesoporous nanocapsules. I performed a TGA just with the essential oil and another one for the silica nanocapsules loaded with the oil. I identified the peak associated to oil degradation around T=300°C in the TGA for the oil, however, when I did the TGA for the nanocapsules loaded with the oil the temperature shifted 10°C higher. Can the encapsulation be somehow related to this phenomenon? if so, do you have an idea how? could it be a problem associated with the procedure?
Conditions:
100mL/min N2
Tramp= 10°C/min
Ti=25°C
Tf=800°C
Thanks for your help!
