I have an interesting case in which I have two convoluted crystallization peaks while cooling my polymer from the melt. Both peaks are forming the same crystal polymorph; the dual Tc represents the same crystal nucleating in two different ways (the higher Tc from an interface, and the second from the bulk).
Classical Avrami analysis makes it challenging to separate the influence of multiple crystallization events - and due to the nature of my material it is difficult to perform isothermal crystallization. I found an excellent paper from Wang et al. (linked here) which identifies a method for isothermal analysis of concomitant crystallization. However, I do not see a way to apply this in a non-isothermal process. I would like to be able to analyze the kinetics in order to find the Avrami exponent of each peak separately - I am hypothesizing that the exponent will be different due to the nucleation method.
I would sincerely appreciate if anyone can point me in the right direction for non-isothermal kinetic analysis of double crystallization events.
