The research presented here is an attempt to develop an innovative and environmentally friendly material based on bacterial nanocellulose (BNC), which will be able to replace both animal skins and synthetic polymer products. Bacterial nanocellulose becomes stiff and brittle when dried, so attempts have been made to plasticise this material so that BNC can be used in industry. The research presented here focuses on the ecological modification of bacterial nanocellulose with vegetable oils such as rapeseed oil, linseed oil, and grape seed oil. The effect of compatibilisers of a natural origin on the plasticisation process of BNC, such as chlorophyll, curcumin, and L-glutamine, was also evaluated. BNC samples were modified with rapeseed, linseed, and grapeseed oils, as well as mixtures of each of these oils with the previously mentioned additives. The modification was carried out by passing the oil, or oil mixture, through the BNC using vacuum filtration, where the BNC acted as a filter. The following tests were performed to determine the effect of the modification on the BNC: FTIR spectroscopic analysis, contact angle measurements, and static mechanical analysis. As a result of the modification, the BNC was plasticised. Rapeseed oil proved to be the best for this purpose, with the help of which a material with good strength and elasticity was obtained.
本文所介绍的研究旨在开发一种基于细菌纳米纤维素（BNC）的创新型环保材料，该材料将能够替代动物皮革和合成聚合物产品。细菌纳米纤维素干燥后会变得坚硬易碎，因此人们尝试对这种材料进行增塑，以便BNC能够应用于工业领域。本文所呈现的研究聚焦于用菜籽油、亚麻籽油和葡萄籽油等植物油对细菌纳米纤维素进行生态改性。同时还评估了天然来源的增容剂对BNC增塑过程的影响，如叶绿素、姜黄素和L - 谷氨酰胺。BNC样品用菜籽油、亚麻籽油和葡萄籽油，以及这些油与上述添加剂的混合物进行改性。改性通过真空过滤使油或油混合物通过BNC来进行，其中BNC充当过滤器。为确定改性对BNC的影响，进行了以下测试：傅里叶变换红外光谱分析、接触角测量和静态力学分析。改性的结果是BNC被增塑。事实证明，菜籽油最适合此用途，借助它可获得具有良好强度和弹性的材料。
