Ion of temperature (T) is usually calculated from the following equation [40,41]:T TXt =T(dH/dT )dT /T(dH/dT )/dT(2)in which T0 and T are the onset and end crystallization temperature, and dH/dT may be the heat flow charge. In nonisothermal crystallization, the time scale t is usually transformed from the temperature T from the equation: t = ( T0 – T )/ (3) in which is the cooling fee. For that reason, the graph on the relative degree of crystallinity Xt versus time t may be plotted. Avrami equation is generally utilized to analyze the isothermal crystallization kinetics through the equation: X (t) = one – exp(-ktn ) (4) where Xt is the relative degree of crystallinity, t is crystallization time, n is the Avrami exponent, and k is really a crystallization fee constant. n generally varies amongst 1 and 4 and may be influenced by the combined effect of nucleation and growth [42]. The double logarithmic form of this equation is: ln[-ln(one – Xt )] = nlnt lnk (five) By plotting the graph of ln[-ln(1 – Xt )] vs. lnt, the values of n and lnk can be calculated by fitting the experimental data. Since the Avrami equation describes the isothermal crystallization process, Jeziorny recommended a strategy to modify the parameter k by introducing the cooling rate to describe the nonisothermal crystallization: ln k c = (ln k )/ (6)The relative percentage crystallinity of phase (c) was calculated through the following equation: c =(one – ) (1 – ) (one – )(seven)Polymers 2021, 13,6 ofPolymers 2021, 13, x FOR PEER Critique where6 of 19 (1 – ) is definitely the crystallinity of each phase and is calculated by H/Hu .

A compact piece of the sample was minimize and positioned among glass covers, melted at 200 [46] for 5 min, and cooled slowly to permit full crystallization. Then, the melted at 200 C [46] for 5 min, and cooled slowly to permit complete crystallization. Then, the film samples had been observed by PLOM. film samples had been observed by PLOM.3.
