摘要

摘要我们介绍了聚合物流变学的基本原理和良好实践,特别是为学院或大学的教师或讲师提供教育,以及为初学者提供研究,他们可以将本文作为自己的自学资源。使用平行板振荡流变仪的实验方法的基本考虑,以及估计存储、G′和损耗、G〃模量的幂律依赖性的逐步指南,以及估计f时的弛豫时间  交叉  G′−G′′${f}_强调了使用商业图形软件、手动图形方法和商业流变仪软件等各种方法在终端区进行的测量。描述并比较了使用不同方法进行数据解释的良好实践,其中手动图形方法或商业图形软件的结果与商业流变仪软件的结果相当。为了更好地理解,还提供了几个适用于教学和自学活动的例子和练习。

Basic principle and good practices of rheology for polymers for teachers and beginners
Abstract We present a basic principle and good practices of the rheology of polymers, particularly for teachers or lecturers at colleges or universities for educational purposes, as well as for beginner researchers who may refer to this article as their self-learning resources. Basic consideration of the experimental methods using parallel-plate oscillatory rheometer and step-by-step guidelines for the estimation of the power law dependence of storage, G′ and loss, G″ modulus as well as the estimation of the relaxation time at f   cross   G ′ − G ′′ ${f}_{\,\mathrm{cross}}^{\,{G}^{\prime }-{G}^{\prime \prime }}$ at terminal zone using various approaches such as commercial graphical software, manual graphical approach and commercial rheometer software are highlighted. Good practices for data interpretation using different approaches are described and compared where the outcomes revealed the manual graphical approach or commercial graphical software yield comparable results with the commercial rheometer software. In order to have better insight, several examples and exercises which are applicable for teaching and self-learning activities are also provided.
