Stereocomplex-affected crystallization behaviour of PDLA in PDLA/PLDLA blends

In the presence of SC crystals, the spherulite growth rate of PDLA decreased, whereas its overall crystallization rate increased.

How to regulate the isothermal growth rate of polymer spherulite without changing its molecular composition?

A new method has been invented to control the spherulite growth rate of isothermally crystallized PBS without changing its molecular composition.

Important Matters of Non-Isothermal Crystallization Method

Non-isothermal crystallization method was performed for pure PLLA and a blend of 50/50 wt% PEO/PLLA samples. The spherulite radial growth rate was calculated and compared to what was acquired using the isothermal crystallization method. It is found that both the fitting order and the decimal number of the fitting polynomial functions heavily affect the resultant spherulite growth rate at different temperatures. It is also important to note that some subtle yet important features might be missed using the quick alternative, such as in the pure PLLA system.
