Specialty paper (e.g. cigarette paper and battery diaphragm paper) requires extremely high strength properties. The addition of strength agents plays an important role in increasing strength properties of paper. Nanocrystalline cellulose (NCC), or cellulose whiskers, has the potential to enhance the strength properties of paper via improving inter-fibers bonding. This paper was to determine the potential of using carboxylated nanocrystalline cellulose (CNCC) to improve the strength properties of paper made of cellulosic fiber or poly (vinyl alcohol) (PVA) fiber. The results indicated that the addition of CNCC can effectively improve the strength properties. At a CNCC dosage of 0.7%, the tear index and tensile index of the cellulosic paper reached the maximum of 12.8 mN m2/g and 100.7 Nm/g, respectively. More importantly, when increasing the CNCC dosage from 0.1 to 1.0%, the tear index and tensile index of PVA fiber paper were increased by 67.29%, 22.55%, respectively.
特种纸（如卷烟纸和电池隔膜纸）需要极高的强度性能。添加增强剂对于提高纸张的强度性能起着重要作用。纳米纤维素（NCC）或纤维素晶须，通过改善纤维间的结合，可以提高纸张的强度性能。本文旨在确定使用羧基化纳米纤维素（CNCC）来提高由纤维素纤维或聚乙烯醇（PVA）纤维制成的纸张的强度性能的潜力。结果表明，添加 CNCC 可以有效提高纸张的强度性能。在 CNCC 用量为 0.7%时，纤维素纸的撕裂指数和抗张指数分别达到 12.8mN·m2/g 和 100.7Nm/g 的最大值。更重要的是，当 CNCC 用量从 0.1 增加到 1.0%时，PVA 纤维纸的撕裂指数和抗张指数分别提高了 67.29%和 22.55%。
