中文摘要 | crystalline morphologies of spin-coated poly(l-lactic acid) (plla) thin films under different conditions are investigated mainly with atomic force microscopy (afm) technique. when plla concentration in chloroform is varied from 0.01 to 1% gradually, disordered structure, rod-shape and larger spheres aggregates are observed in thin films subsequently. under different annealing temperature, such as at 78, 102, 122 degrees c, respectively, we can find most rod-like crystalline aggregates. interestingly, we observed that nucleation sites locate at the edge of the holes at the original crystalline stage. then, these holes developed to form chrysanthemum-like and rods subsequently with annealing time meanwhile the size and the shape of crystalline aggregate are changed. in addition. effect of substrate and solvent on morphology is also discussed. on the other hand, the possible mechanism of crystalline morphology evolution is proposed. |
