Subcell-matched epitaxy of normal long chain compounds on polyethylene: II. On the (100) plane

Abstract

Polythylene films with surfaces bounded with the (100) plane were prepared by high drawing of ultra-high molecular weight polyethylene mats made of solution-grown crystals. Normal long chain compounds, which are the same as examined in Paper I, were crystallized from solution by solvent evaporation and from the melt on the polyethylene films. Epitaxial crystallization was observed for those compounds that have the same orthorhombic subcell as the polyethylene unit cell. In the epitaxial overgrowth, the normal long chain compounds are arrayed with their axis parallel to the chain axis of polyethylene on the (100) polyethylene plane, performing the lattice coincidence of the (100) polyethylene plane with their corresponding subcell plane, irrespective of the chemical and crystal structures of the crystallized materials.
