AbstractIn this paper, the Flory–Huggins theory is utilized to formulate two essential equations for determining the compositions of the different phases resulting from the phase separation behavior of polymer blends. The equations use a graphical approach to determine the numerical outcomes of the compositions of the different phases, serving as a universally applicable illustration. The results show that when the Flory–Huggins interaction parameter is less than the critical value, the graphs of the equations have no intersection point, indicating the absence of phase separation. Conversely, when the Flory–Huggins interaction parameter equals the critical value, the graphs of the equations display a single intersection point. Furthermore, if the parameter value exceeds the critical value, the graphs of the equations show two symmetrical intersection points, indicating that phase separation can occur. The present study also includes a discussion on the correlations between the compositions of the different phases and the Flory–Huggins interaction parameter.DisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

AbstractThermal analysis of polyacrylonitrile (PAN) fibers is commonly employed to assess the chemical and physical changes occurring during the pre-oxidation stage. However, in actual pre-oxidation processes, PAN fibers are stretched to a certain extent (approximately 5%) to prevent fiber shrinkage. Consequently, the pre-oxidation process of PAN fiber is influenced not only by temperature and atmosphere but also by the stretching tension. In this study, two types of PAN fiber samples with different crystal structures were utilized alongside four different processing methods (PAN powder, unfixation, physical fixation, and chemical fixation) to generate three degrees of fixed stretching. These included PAN powder and unfixed PAN fiber samples (without fixation tension), physically fixed PAN fiber with relatively weak fixation tension, and chemically fixed PAN fiber with strong fixation. Through a comparison of these samples, it was observed that the fixation tension aided in preserving the crystal structure during the heating process, significantly reducing the cyclization rate of the PAN fibers. The cyclization reaction rate of PAN fiber A, initially at 85% without any fixation, decreased to 66% after physical fixation and dropped to 56% after chemical fixation. For PAN fibers with distinct crystal morphologies, the impact of the fixation tension was more prominent for PAN fibers with larger crystal sizes and lower orientation. Additionally, the presence of crystal orientation facilitated the occurrence of the cyclization reactions.Keywords: Differential scanning calorimetry (DSC)fixation tensionpolyacrylonitrilewide-angle X-ray diffraction (WAXD) AcknowledgmentsThanks to the Shanghai Synchrotron Radiation Facility (SSRF) and the Beijing Synchrotron Radiation Facility (BSRF) for their assistance and support in analyzing the WAXD data in this study.

摘要聚丙烯腈(PAN)纤维的热分析通常用于评价预氧化阶段发生的化学和物理变化。然而，在实际预氧化过程中，PAN纤维被拉伸到一定程度(约5%)以防止纤维收缩。因此，PAN纤维的预氧化过程不仅受温度和气氛的影响，还受拉伸张力的影响。本研究利用两种不同晶体结构的PAN纤维样品，采用四种不同的加工方法(PAN粉末、不固定、物理固定和化学固定)，产生三种程度的固定拉伸。包括PAN粉末和未固定的PAN纤维样品(无固定张力)，物理固定的PAN纤维相对较弱，化学固定的PAN纤维具有很强的固定力。通过对这些样品的比较，观察到固定张力有助于在加热过程中保持PAN纤维的晶体结构，显著降低了PAN纤维的环化速率。PAN纤维A的环化反应速率在未固定时为85%，经物理固定后降至66%，经化学固定后降至56%。对于具有不同晶体形态的PAN纤维，固定张力对晶体尺寸较大、取向较低的PAN纤维的影响更为突出。此外，晶体取向的存在有利于环化反应的发生。关键词:差示扫描量热法(DSC)固定张力聚丙烯腈广角x射线衍射(WAXD)致谢感谢上海同步辐射中心(SSRF)和北京同步辐射中心(BSRF)对本研究WAXD数据分析的帮助和支持。作者对BSRF和SSRF的光束线科学家，特别是光莫和李志宏的帮助表示感谢。我们保证这篇手稿是原创的，没有被发表过，在被Journal of Macromolecular Science, Part b考虑期间不会提交到其他地方发表。此外，该研究没有被分成几个部分来增加提交的数量，并且在一段时间内提交给不同的期刊或一个期刊。没有捏造或操纵数据(包括图像)来支持结论。这篇文章不包含任何研究与人类参与者或动物进行的任何作者。从所有参与研究的个体参与者处获得知情同意。披露声明作者未报告潜在的利益冲突。本研究由辽宁省潘鹏学者计划资助。
