| 中文摘要 | epitaxial crystallization of syndiotactic polypropylene (spp) on 2-quinoxalinol (2-quin) yields, in the lower part of the crystallization range, the less common and metastable form ii based on the packing of isochiral helices, rather than the stable antichiral form i. the contact plane is (110)(ii). form ii exits only as a thin layer (< 50 nm) near the substrate surface. during further growth away from the surface, a transition takes place to the disordered form i, observed in "conventional" thin film growth. the epitaxial relationship rests only partly on dimensional matching with the chain axis repeat distance (which would be valid for both forms i and ii) and on interchain distances. whereas a better dimensional match would be achieved with form i, selection of the isochiral form ii results from better correspondence of the surface topographies of the deposit (110)(ii) spp and substrate 2-quin (001) contact faces. |
