摘要
通过反复冷冻—溶融法制备了细菌纤维素/聚乙烯醇/聚乙二醇(BC/PVA/PEG)复合水凝胶,并采用扫描电镜、红外光谱、X-射线衍射和拉力测试等手段对水凝胶的结构和性能进行表征。拉伸力学性能测试结果表明,随着PEG的加入,水凝胶的力学性能得到显著增强。
In the study, different BC/PVA/PEG composite hydrogels were produced by using simple freeze-thaw cycles and were characterized by using scanning electron microscopy, infrared spectroscopy, X-ray diffraction, and tensile test. As expected, tensile strength results showed that the addition of PEG significantly improved the mechanical properties of the composite hydrogels.
