介绍了一种新的、简化的制备纤维素模型表面的方法。通过旋涂将非极性纤维素衍生物三甲基甲硅烷基纤维素（TMSC）沉积到未处理的硅基底上，之后通过气相酸水解将涂覆的TMSC再生回纤维素。通过优化旋涂工艺参数，获得了粗糙度变化最大为20 nm左右的光滑纤维素膜。3纳米。这些模型表面具有明确的形态和化学结构，并易于制备，为探索涉及纤维素的各种过程中发生的分子水平现象提供了极好的手段。薄膜的特征在于使用原子力显微镜来说明的形态和X射线光电子能谱，以确定层的化学结构。(C)2003爱思唯尔科技有限公司版权所有。
A new, simplified method for preparing model surfaces of cellulose is introduced. Non-polar cellulose derivative trimethylsilyl cellulose (TMSC) was deposited onto untreated silicon substrate by spin coating, after which the coated TMSC was regenerated back to cellulose by vapour phase acid hydrolysis. By optimising the parameters of spin coating, a smooth cellulose film of ca 20 nm was obtained with roughness variation of max. 3 nm. With the well-defined morphology and chemical structure, combined with easy preparation, these model surfaces provide excellent means to explore the molecular level phenomena, taking place during various processes involving cellulose. Films were characterized using atomic force microscopy to illustrate the morphology and X-ray photoelectron spectroscopy to determine the chemical structure of the layers.
