Inter-fibre bonding of mechanical pulp fibres

纤维间的结合决定了纸张中形成的纤维的网络结构，从而基本上决定了纸张的所有性能，包括结构、机械、光学、热学和电学性能。为了建立测定纤维间粘合的方法，人们做了许多努力。然而，这些方法的有效性一直受到各种各样的讨论。所提出的研究将开发出利用原子力显微镜测量纤维间键合的全新方法。该方法的更大优点是，不仅可以显示纤维间的键合，还可以显示键合区域的表面化学和纳米表面粗糙度。预计本研究结果将为纤维间键合的基本原理提供新的认识。

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.
