HIGH-THROUGHPUT MEASUREMENTS OF CRYSTALLIZATION OF POLYOLEFIN BLEND THIN FILMS

摘要

The combinatorial approach is an excellent method of characterizing the effectiveness of 4-biphenyl carboxylic acid as a nucleating agent for polypropylene thin films. The evolution of the morphological changes induced by the presence of the nucleating agent within the film was followed as a function of film thickness and undercooling temperature. Further results from this combinatorial study, including the onset of dewetting at long times were measurable in a quantitative manner. This methodology, having an inherent flexibility of experimental design for probing requisite parameter space, should be applicable to the study of nucleating agents in other polymer films as well.
