Abstract

The aim of this paper is to present image analysis as a useful technique for fast, reliable and non-destructive detection of dimensional and structural changes in polymers. The possibility of applying image analysis was demonstrated in the case of solvent-induced crystallization of poly(ethylene terephthalate) (PET) containers filled with commonly used organic solvents: chlorobenzene, isophorone, xylene, Espesol, Shellsol A 100, Solvesso 150, propylene glycol, glycerin and water and subjected to the storage stability test at 54 °C for 14 days (CIPAC 1-MT 46.1.3). In addition, the obtained results were analyzed using one-step analysis of variance (ANOVA) combined with the Duncan’s statistical test (p<0.05). According to the achieved results, three main impacts of the presented paper could be distinguished: 1) dimensional and transparency changes could be precisely followed by image analysis in both following cases: for small changes in water, as well as for significant ones in chlorobenzene; 2) a correlation between the changes in the degree of crystallinity and transparency could be obtained without the continuous material testing by DSC; 3) image analysis is potentially applicable for assessment of other crystalline polymers.

图像分析是快速检测聚对苯二甲酸乙酯容器尺寸和结构变化的有效工具

本文的目的是介绍图像分析作为一种有用的技术，用于快速，可靠和无损地检测聚合物的尺寸和结构变化。在溶剂诱导结晶的情况下，应用图像分析的可能性在聚对苯二甲酸乙酯(PET)容器中进行了演示，该容器中填充了常用的有机溶剂:氯苯、异戊酮、二甲苯、Espesol、Shellsol A 100、Solvesso 150、丙二醇、甘油和水，并在54°C下进行了14天的储存稳定性测试(CIPAC 1-MT 46.1.3)。采用一步方差分析(ANOVA)结合Duncan’s统计检验对所得结果进行分析(p<0.05)。根据所取得的结果，可以区分出本文的三个主要影响:1)在以下两种情况下，图像分析可以精确地跟踪尺寸和透明度的变化:对于水的微小变化，以及氯苯的显著变化;2)不需要连续的DSC测试材料，结晶度和透明度的变化可以得到相关性;3)图像分析可能适用于其他结晶聚合物的评估。
