| 英文摘要 | The crystallization behavior of poly(L-lactic acid) (PLLA) it in anodic alumina oxide templates (AAO),was investigated by differential scanning calorimetry (DSC), and wide-angle-X-ray diffraction (WAXD). During heating from the glassy state, the crystallization, of infiltrated PLLA was unexpectedly enhanced as compared with bulk PLLA. The cold crystallization temperature of infiltrated PLLA from the glassy state was much lower than that of bulk PLLA. The half-crystallization time (t(1/2)) of infiltrated PLLA at 75 degrees C decreased with the diameter of AAO nanopores. The glass transition temperature of PLLA was not influenced by the geometrical Confinement, The enhanced crystallization from the glassy state was explained by surface-induced nucleation of AAO walls on PLLA. Our results provide the first observation of enhanced cold crystallization of polymers in confined geometry, |
