In this work, chitin-curcumin based polyurethane elastomers (PUEs) were prepared by step growth polymerization technique using hydroxy terminated polybutadiene (HTPB), hexamethylene diisocyanate (HDI), chitin and curcumin. The molecular characterization was done by using FTIR and SS HNMR techniques. The surface morphology and thermal stability was studied by scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA), respectively. Degree of absorption and swelling characters were also determined in water as well as in DMSO. The crystalline behavior of prepared elastomers was checked by using X-ray diffraction (XRD) and differential scanning calorimeter (DSC). Results presented that crystallinity of elastomers increased by increasing the content of chitin due to formation of more ordered structure.
在这项工作中，通过逐步聚合技术，使用端羟基聚丁二烯（HTPB）、六亚甲基二异氰酸酯（HDI）、壳聚糖和姜黄素制备了壳聚糖-姜黄素基聚氨酯弹性体（PUE）。通过傅里叶变换红外光谱（FTIR）和固态核磁共振波谱（SS HNMR）技术进行了分子表征。通过扫描电子显微镜（SEM）和热重分析（TGA）分别研究了表面形貌和热稳定性。在水中和 DMSO 中还测定了吸收和溶胀特性。通过 X 射线衍射（XRD）和差示扫描量热法（DSC）检查了制备的弹性体的结晶行为。结果表明，由于形成更有序的结构，弹性体的结晶度随着壳聚糖含量的增加而增加。
