Novel bio-inspired materials derived from crystalline nanocellulose (CNC) have been tested as wood consolidants. A suspension of CNC, produced by acid hydrolysis of cellulose and used as such or mixed with lignin and/or siloxane derivatives (PDMS), was applied on rotted wood samples of Norway spruce. X-Ray diffraction analysis on CNC powder showed high crystallinity index. Dynamic light scattering (DLS) measurement indicated a nearly uniform particle size distribution with an average hydrodynamic diameter for pure CNC smaller than that in the mixtures. Raman and FTIR spectroscopies suggested interactions between lignin, PDMS and CNC components.

The storage modulus of wood samples, measured by Dynamic Mechanical Analysis on the same specimen before and after consolidation, confirmed the efficiency of pure CNC, which displayed a considerable improvement of stiffness. A substantial increase of E’ was observed particularly for most decayed classes. These results suggest a closer interaction between nanocellulose and decayed wood.

源自晶体纳米纤维素（CNC）的新型生物启发材料已作为木材固结剂进行了测试。通过将纤维素酸水解生产的CNC悬浮液原样使用或与木质素和/或硅氧烷衍生物（PDMS）混合使用，然后将其悬浮在挪威云杉的烂木样品上。CNC粉末的X射线衍射分析显示出较高的结晶度指数。动态光散射（DLS）测量表明，纯CNC的平均流体动力学直径几乎小于混合物中的粒径分布，并且平均流体动力学直径较小。拉曼光谱和FTIR光谱学表明，木质素，PDMS和CNC组件之间存在相互作用。

木材样品的储能模量（通过动态力学分析在固结之前和之后在同一样品上进行测量）证实了纯CNC的效率，显示了硬度的显着提高。尤其是对于大多数衰变类别，观察到E'显着增加。这些结果表明纳米纤维素和腐朽的木材之间的相互作用更紧密。
