【摘要】 用电子显微镜观察了聚全氟乙丙烯试料的自由表面形态结构,指出试料不同,自由表面形态也不同,有的由无规片层组成,有的则由无规和规整两种片层组成,提出了两种片层结构本质的设想,用另一些实验数据支持这种设想,根据设想所推测的试料的力学性能与实测值基本相符。更多还原

【Abstract】 The morphology of the free surface of PEP copolymer samples was observed with TEM. It is shown that the morphology of the free surfaces of different samples varies one from another. Some consisted of "random lamellae", while others consisted of both "random and regular lamellae". The structural nature of these two kinds of lamellae is discussed and is shown by other experimental evidence. The mechanical properties of the samples predicted on the basis of this consideration are in accordance with experimental results.更多还原
