制备了一系列不同十二烷基苯磺酸钠(SDBS)胶束量的壳聚糖(CS)复合膜(CS/SDBS).通过傅立叶红外(FT-IR)、热重分析(TGA)、X射线衍射(XRD)和扫描电镜(SEM)等方法研究了SDBS胶束量对壳聚糖结构、形态以及力学性能等方面的影响.红外光谱(FT-IR)表明,在SDBS胶束和壳聚糖之间形成了强的相互作用,适量的SDBS胶束能有效地提高壳聚糖的力学性能.与纯的壳聚糖相比,当SDBS的添加量为0.9%(质量分数)时,复合材料的拉伸强度(σb)和断裂伸长率(εb)分别提高了25.4%和18.7%.
A series of CS / SDBS micelles with different SDBS micelles were prepared by FT-IR, TGA, X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to study the effect of SDBS micelles on the structure, morphology and mechanical properties of the chitosan.FTI spectroscopy showed that in SDBS micelles and shells The strong interaction between polysaccharides and SDBS micelles can effectively improve the mechanical properties of chitosan.Compared with pure chitosan, when the amount of SDBS is 0.9% (mass fraction) The tensile strength (σb) and elongation at break (εb) of composites increased by 25.4% and 18.7%, respectively.
