| 中文摘要 | a large number of lozenge-shaped and sandwiched polystyrene-block-poly(l-lactide) (ps-b-plla) single crystals were prepared by the self-seeding technique. the single crystals were nearly monodispersed in both thickness and diameter. they are well-dispersed because of the steric stabilization offered by tethered ps in p-xylene, which is a good solvent for ps. the suspensions were observed to separate into a transparent upper phase and a turbid lower phase. the lower phase showed uniform iridescent stripes extending over the, whole tube between crossed polarizers. the birefringence demonstrates he liquid crystal order, and the uniform stripes reveal that the phase is a well-oriented single domain. the phase transition concentration is rather low. polarizing light microscopy (plm) images show schlieren texture and thread like texture. small-angle x-ray scattering (saxs) results showed that the single crystals in the liquid crystal phase oriented horizontally a vertical repeat distance of about 70 nm. additionally, the possible structure of liquid crystal phase is being discussed. the novel disclike colloidal particle might be useful for anisotropic photonic materials; |
