Abstract

Poly(2-ethyl-2-oxazoline) (PEOX) belongs to the family of polymers known for their beneficial characteristics, such as hydrophilicity (water solubility), biocompatibility and being eco-friendly to the environment. PEOX has attracted the attention of several scientists, making its use very widespread and beneficial due to its intriguing performances suitable to develop advanced materials for strategic applications. Our research described here investigated the structural, vibrational, thermal and dielectric properties of PEOX, and correlated all these properties for in depth comprehension of the compound’s behavior. PEOX was characterized by infrared and Raman spectroscopies to depict the characteristic vibrational bands of PEOX. Thermal stability was characterized by thermogravimetric analysis, which revealed good thermal stability below 327°C; above this temperature PEOX undergoes thermal decomposition. Furthermore, the electrical and dielectric properties of PEOX were analyzed. The data depicted a strong dispersion dependence on both temperature and frequency; thus, highlighting its potential use for the development of advanced functional materials.

聚（2-乙基-2-恶唑啉）的振动、热分析和介电性能

聚（2-乙基-2-恶唑啉）（PEOX）属于聚合物家族，以其有益的特性而闻名，如亲水性（水溶性），生物相容性和对环境的友好性。由于其有趣的性能适合开发用于战略应用的先进材料，PEOX已经吸引了几位科学家的注意，使其使用非常广泛和有益。我们的研究描述了PEOX的结构、振动、热和介电性能，并将所有这些性能进行了关联，以深入了解化合物的行为。利用红外光谱和拉曼光谱对PEOX进行了表征，描绘了PEOX的特征振动带。热稳定性通过热重分析表征，在327℃以下具有良好的热稳定性；在这个温度以上，PEOX就会发生热分解。此外，还分析了PEOX的电学和介电性能。数据显示，色散对温度和频率都有很强的依赖性；因此，突出了其在开发先进功能材料方面的潜在用途。
