Inter-fibre bonding determines the network structure of fibres formed in paper thus determines basically all the paper properties, including structural, mechanical, optical, thermo and electrical properties of a paper sheet. Many efforts have been made to establish methods for determining inter-fibre bonding. However, the validity of these methods have been under various discussions. The proposed research will develop totally new methods for inter-fibre bonding measurement by using AFM. The greater advantages of the proposed method are that, not only the inter-fibre bonding, but also the surface chemistry as well as the nano-surface roughness of the bonded area, can be revealed. It is expected that the results of this research will provide new understanding of the fundamentals of inter-fibre bonding.

纤维间结合决定了纸中形成的纤维的网络结构，因此基本上决定了所有的纸性能，包括纸张的结构、机械、光学、热和电性能。 已经做出了许多努力来建立用于确定纤维间结合的方法。 然而，这些方法的有效性一直处于各种讨论之中。 该研究将为利用原子力显微镜测量纤维间结合力提供全新的方法。 所提出的方法的更大的优点是，不仅纤维间的结合，而且表面化学以及纳米表面粗糙度的结合区域，可以揭示。 预计这项研究的结果将提供新的理解纤维间粘结的基本原理。
