| 中文摘要 | isotactic polypropylene in its a modification (alpha ipp) crystallises epitaxially on polytetrafluoroethylene (ptfe) and several hemiacids or salts of substituted benzoic acids via a novel contact plane, namely (110): so far, the only known contact plane involved in alpha ipp homo- and hetero-epitaxies was (010). in spite of its complicated architecture (alternation of antichiral helices with different azimuthal settings), the (110)(alpha ipp) contact plane displays well defined, if not prominent, rows of methyl side chains parallel to the crystallographic (112) direction (at 57 degrees to the c-axis) and approximate to 5.5 angstrom apart. the matching contact planes of the substrates display linear gratings made of rows of e.g. chlorine atoms or ptfe chains with similar approximate to 5.5 angstrom inter-row or interchain distances. various morphologies are observed in ipp thin films crystallised at different cooling rates in the presence of ptfe; they can be analysed in terms of a succession and interplay of successive epitaxies: initial alpha ipp/ptfe heteroepitaxy, followed by alpha ipp/alpha ipp and gamma ipp/alpha ipp homoepitaxies.
