近年来，非平衡态自组织过程作为一种新的研究方法，被广泛地应用于许多功能材料的开发。在许多情况下，使用无定形聚合物，而半结晶聚合物尽管重要，但很少使用。在本研究中，我们基本上研究了聚酰胺的晶体结构，结晶过程，并从聚合物溶液的非平衡状态，通过使用缓慢的相分离和结晶过程的内部结构。我们能够观察到晶体薄片从粒子中心扭曲生长。在这些薄片层之间，产生了狭窄的孔隙。从这个调查，我们开发了一种新的方法来创建功能材料的聚酰胺，半结晶聚合物。多孔球形颗粒可以适当地应用于功能材料，例如吸附材料、催化剂载体材料等。应用聚合物科学杂志90：2428-2432，2003
Recently a number of investigations have focused on the self-organization process from the nonequilibrium state as a new technique that may be used to develop many functional materials. In many cases, amorphous polymers were used and semicrystalline polymers were seldom used in spite of their importance. In this study, we basically investigated the crystal structure, crystalline process, and inner structures of polyamide by using slow phase separation and crystallization process from the nonequilibrium state of the polymer solution. We were able to observe the crystalline lamella growing twisted from the center of the particle. Between these lamella layers, narrow pores were created. From this investigation, we developed a new method to create functional materials of polyamide, the semicrystalline polymer. Porous spherical particles may be properly applied to functional materials such as adsorption materials, catalyst support materials, and so on. © 2003 Wiley Periodicals, Inc.
