摘要

摘要:本研究旨在评价纤维素纳米纤维及其对历史纸质文献中最常用的表面上浆物质淀粉和明胶的影响。在本研究中，纤维素纳米纤维的浓度为1%重量与乙醇作为悬浮液，并用于处理未上浆样品和含有淀粉和明胶上浆的样品。结果表明，应用纤维素纳米纤维处理可提高未上浆样品和含淀粉上浆样品的pH值。老化后，样品的pH值略有下降。纤维素纳米纤维处理提高了样品的抗拉强度。在加速老化后，含有淀粉和明胶的样品和处理过的样品的抗拉强度比未处理的样品增加。明胶上浆样品和处理过的淀粉上浆样品的颜色变化分别最小(∆E)，比色效果最好。老化前后样品的接触角测试结果表明，纤维素纳米纤维处理并没有增加纸张的抗湿性，也没有阻止纸张表面受潮。

The Effect of Cellulose Nanofibers on Paper Documents Containing Starch and Gelatine Sizing

Abstract This study aimed to evaluate cellulose nanofibers and their effects on starch and gelatine as the most common surface sizing substances used in historical paper documents. In this study, cellulose nanofibers with a concentration of 1% by weight were prepared as a suspension with ethanol and used for the treatment of unsized samples and samples containing starch and gelatine sizing. The results showed that the application of cellulose nanofiber treatment increased the pH of unsized samples and samples containing starch sizing. After aging, there was a slight decrease in the pH of the samples. Cellulose nanofiber treatment increased the tensile strength of the samples. After accelerated aging, the tensile strength of samples containing starch and gelatine sizing and treated samples increased compared to untreated samples. Samples containing gelatine sizing and samples containing treated starch sizing showed the least amount of colour changes (∆E), respectively, and had the best colorimetry results. The results of the contact angle test of the samples before and after aging showed that cellulose nanofiber treatment did not increase the resistance of the paper to wetting and did not prevent the paper surface from getting wet.
