Abstract

The objective of this work was to fabricate nanofibres composed of polycaprolactone (PCL) and κ-carrageenan (kC) by employing an anionic surfactant, sodium bis(2-ethylhexyl) sulfosuccinate (AOT). This study examined the role of the surfactant in PCL/kC/AOT (hybrid) nanofibre preparation using SEM, AFM, Fourier transform infrared spectroscopy, XRD and DSC. The wettability and water uptake percentage of the nanofibres were investigated. An antimicrobial study was conducted against bacterial strains using a colony-counting assay, and changes in bacterial morphology were monitored using TEM. The results demonstrated that the hybrid nanofibres had a uniform and smooth structure, which might be attributed to the improved compatibility between polymers in the presence of the surfactant. The incorporation of AOT in the matrix resulted in a reduction in the mean fibre diameter and surface roughness. The hybrid nanofibres increased water absorbency is evidence of their high hydrophilicity, which can be explained by the simultaneous impact of kC and AOT. The hybrid nanofibres exhibited effective activity against Staphylococcus aureus and Escherichia coli. © 2024 Society of Chemical Industry.

制备表面活性剂辅助聚己内酯/κ-卡拉胶纳米纤维

本研究的目的是通过使用阴离子表面活性剂--双（2-乙基己基）磺基琥珀酸钠（AOT），制备由聚己内酯（PCL）和κ-卡拉胶（kC）组成的纳米纤维。本研究使用扫描电镜、原子力显微镜、傅立叶变换红外光谱、XRD 和 DSC 对表面活性剂在 PCL/kC/AOT（混合）纳米纤维制备中的作用进行了研究。研究了纳米纤维的润湿性和吸水率。使用菌落计数法对细菌菌株进行了抗菌研究，并使用 TEM 监测了细菌形态的变化。结果表明，混合纳米纤维具有均匀光滑的结构，这可能是由于在表面活性剂的存在下聚合物之间的相容性得到了改善。在基质中加入 AOT 后，纤维的平均直径和表面粗糙度都有所降低。杂化纳米纤维吸水性的增加证明了它们的高亲水性，这可以用 kC 和 AOT 的同时影响来解释。混合纳米纤维对金黄色葡萄球菌和大肠杆菌具有有效的抗菌活性。© 2024 化学工业协会。
