Abstract

In this work, an extract of the Tamarix hispida (TH-10) was prepared in 10 vol.% water-ethanol solution. Based on the properties of antioxidant, and anti-inflammatory activity, various gelatin films containing (10–15 wt.%) gelatin were obtained. The fabricated gelatin films containing TH-10 extract were used as wound dressings for burns. Their deformation properties, physical and mechanical properties, and SEM micrographs were defined. An additional film structure was determined by using a Fourier transform infrared spectrometer (FT-IR). The strength of polymer films containing TH-10 depends on gelatin content. This indicates that the gelatin film binds the TH-10 with the help of hydrophobic interactions. It was found that the higher amount of gelatin leads to lower tear resistance of films. This is due to the formation of micro-cracks on the surface of films leading to their easy rupture. During the study of tensile strength, it was proven that the optimal amount of glycerin in the film is 5 vol.%. The polymer film containing 12 wt.% gelatin and 1 wt.% TH-10 was recognized as the most effective composition in terms of strength and elasticity properties for application as wound dressing materials.
含有柽柳天然化合物的明胶薄膜机械性能研究
在这项工作中,我们用 10 体积百分比的水乙醇溶液制备了柽柳提取物(TH-10)。根据其抗氧化和抗炎活性的特性,制备出了各种含有(10-15 wt.%)明胶的明胶薄膜。含有 TH-10 提取物的明胶薄膜被用作烧伤的伤口敷料。对它们的变形特性、物理和机械特性以及扫描电镜显微照片进行了定义。此外,还使用傅立叶变换红外光谱仪(FT-IR)确定了薄膜的结构。含有 TH-10 的聚合物薄膜的强度取决于明胶含量。这表明明胶薄膜在疏水相互作用的帮助下结合了 TH-10。研究发现,明胶含量越高,薄膜的抗撕裂性越低。这是由于薄膜表面形成了微裂缝,导致薄膜容易破裂。在拉伸强度研究中,证明薄膜中甘油的最佳用量为 5 wt.%。在强度和弹性方面,含有 12 重量%明胶和 1 重量%TH-10 的聚合物薄膜被认为是最有效的伤口敷料成分。
