自上个世纪60年代以来,人们对聚合物熔体的流动致结晶进行了大量实验研究并提出了相关的理论模型。但是基于应变诱导结晶的传统模型存在着一定的局限性,理论预测值和实验结果也有出入。近年来,人们又提出了一些全新的流动致结晶理论,比如分子模型和唯象模型。本文综述了这些理论模型的理论背景,建模思想以及适用范围等,对比了各个模型的优势和不足,展望了流动致结晶理论研究领域的研究趋势和前景。
Since the 1960s
many experiments of flow-induced crystallization in polymer melts have been conducted and related models have been proposed.However
based on the strain-induced crystallization theory
the classical models have some limitations and their expectation deviates from the experimental results.In recent years
some new model approaches have been adopted to explain the flow-induced crystallization
such as the molecular model and the phenomenological model.This paper will review the essential theory and the applications of the models
compare their advantages and disadvantages
and anticipate the trend in the field of flow-induced crystallization.
