Abstract

Cationic particles are commonly used as wet-end additives in papermaking processes. This study evaluates the effects of cationic cassava starch (CCS) on the mechanical strength of paper made from bacterial cellulose (BC). Acetobacter xylinum was utilised in the production of bacterial cellulose (BC) paper, whereas 3‑chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) was employed in the etherification process of cassava starch to synthesize CCS. Papers containing CCS displayed a more compact surface structure compared to traditional wood-based papers, reaching a brightness level of 97.3 and improving thermal and mechanical characteristics, such as higher tensile strength and is suitable for use as a separator in battery fabrication processes. The results emphasise the possibility of using CCS as a sustainable option in paper production, offering enhanced environmental and mechanical efficiency.

通过添加阳离子木薯淀粉提高细菌纤维素纸的机械和热性能

阳离子颗粒通常用作造纸工艺中的湿端添加剂。本研究评估了阳离子木薯淀粉（CCS）对细菌纤维素（BC）造纸机械强度的影响。在生产细菌纤维素（BC）纸时使用了木质醋酸纤维菌，而在木薯淀粉的醚化过程中使用了 3-氯-2-羟丙基三甲基氯化铵（CHPTAC）来合成 CCS。与传统的木质纸相比，含有 CCS 的纸张显示出更紧凑的表面结构，白度达到 97.3，热性能和机械性能也有所改善，例如抗张强度更高，适合在电池制造过程中用作隔膜。研究结果表明，在纸张生产中使用碳捕集与封存技术是一种可持续发展的选择，可提高环境和机械效率。
