各种非均相添加剂对聚合物结晶的成核作用已被简要地研究1 - 4，有些作者试图了解成核过程的机理5。在碳纤维上的全同立构聚丙烯结晶的检查中，我们显示了基材几何形状对聚合物从熔体结晶成核的重要性6。在这里，我们报告进一步的工作，证实了异质成核剂的有效性取决于它的结构。这些研究的新奇在于我们使用的复制技术，将“非活性”表面转化为表面，容易从聚合物熔体成核结晶。
THE nucleation of polymer crystallization by various heterogeneous additives has been studied empirically1–4some authors have attempted to understand the mechanism of the nucleation process5. In an examination of isotactic polypropylene crystallization on carbon fibres, we showed the importance of substrate geometry on the nucleation of polymer crystallization from the melt6. Here we report further work which confirms that the effectiveness of a heterogeneous nucleant depends on its structure. The novelty of these studies lies in our use of a replication technique to transform “non-active” surfaces into surfaces which readily nucleate crystallization from polymer melts.
