The morphology of PLLA/PBA crystalline/crystalline system reveals abundant morphologies in different crystallization condition. Neat PLLA and PBA usually show Maltese-cross spherulites. However, banded spherulites and branched structures of blends formed in high-temperature region in this work. In addition, fragments morphology is discovered in low-temperature region. These different morphologies are related to the changes of crystallization environment caused by crystalline/crystalline blending.
