In this paper, nanochitin was used as an alternative natural nanomaterial to combine with cellulose fibers for fabricating high-strength paper. Two typical chitin nanowhiskers having contrasting sign of surface charge were compared to evaluate the enhancement performance on paper in details. The results show that nanochitin with positive charges on the surface has a significant effect on the strength properties of the prepared paper, especially on wet strength. When the dosage of chitin nanowhiskers was 2%, the wet strength index was increased to 2.48 N·m/g, which is important for paper-based analytical devices with the common use in liquid analysis. Typical colorimetric glucose assays were successfully performed, suggesting the improved analytical performance on these prepared paper.
本文使用纳米几丁质作为一种替代的天然纳米材料，与纤维素纤维结合用于制造高强度纸张。对比了两种具有相反表面电荷的典型壳聚糖纳米纤维，以详细评估对纸张的增强性能。结果表明，表面带正电荷的纳米几丁质对所制备纸张的强度性能有显著影响，特别是对湿强度的影响。当壳聚糖纳米纤维的用量为 2%时，湿强度指数提高到 2.48 N·m/g，这对于在液体分析中常用的基于纸张的分析器件非常重要。成功进行了典型的比色葡萄糖分析，表明这些制备纸张的分析性能得到了提高。
