中文摘要the branched crystal morphology of linear polyethylene formed at various temperatures from thin films has been studied by atomic-force microscopy (afm), transmission electron microscopy (tem), electron diffraction (ed) pattern and polymer decoration technique. two types of branched patterns, i.e. dendrite and seaweed patterns, have been visualized. the fractal dimension d(f) = 1.65 of both dendrite and some of seaweed patterns was obtained by using the box-counting method, although most of the seaweed patterns are compact. selected-area ed patterns indicate that the fold stems tilt about 34.5degrees around the b-axis and polymer decoration patterns show that the chain folding direction and regularity in two (200). regions are quite different from each other. because of chain tilting, branched crystals show three striking features: 1) the lamella-like branches show two (200) regions with different thickness; 2) the crystals usually bend towards the thin region; 3) the thick region grows faster by developing branches, thus branches usually occur outside the thick region. the branched patterns show a characteristic width w, which gives a linear relationship with the crystallization temperature on a semilogarithmic plot.
