摘要：
The nanostructures and morphologies of neat 1,3: 2,4-dibenzylidene-D-sorbitol (DBS) and DBS/poly(L-lactic acid) (PLLA) films have been investigated by polarizing optical microscopy (POM) and scanning electron microscopy (SEM). The morphology of neat DBS samples prepared from solution had unspecific structures, and no fibrils formed. The DBS nanofibrils were found in DBS/PLLA systems, and the average diameter was only around 20 nm. The DBS architectures could be well tuned by varying the DBS contents and PLLA crystallization temperatures. In addition, nanoporous PLLA structures could be obtained by solvent extraction of the DBS nanofibrils.
