On the crystalline-amorphous supermolecular structure of poly(4-methyl-1-pentene) films cast from solution: experimental evidences and theoretical remarks.

摘要

We regard the formation of crystalline-amorphous structure of polymeric films cast from solution. We pay a special attention to its formation on a level of single quasicrystalline domain, and try to embark on the problem, when a possibly large group of such domains has to be considered. In the former, one is nearly enforced to make use of a modification of the stochastic diffusion-limited aggregation model, first introduced by Witten and Sander. In the latter, certain diffusion-type (Potts-like) models, invented for polycrystalline microstructure formation, could be adopted. When considering the problem on the first level mentioned, one may notice an apparent agreement between experiment and theory, whereas on the second level, some conceptual similarity seems to be attractive.
