A model of the structure of cotton cellulose is proposed, taking into account the presence of a system of slit-like pores between its structural elements. Using 1H-NMR spectroscopy, adsorption and desorption measurements, it was possible to determine the specific surface area of the pore walls of hydrated cotton cellulose. The nature of the change in the degree of crystallinity of cellulose and the specific surface area of its intercrystalline pores at different stages of wetting is shown. It found that the contribution of the porous system to the total specific surface area of cotton cellulose with a crystallinity of 0.7 in adsorption-desorption processes does not exceed 70%.

纤维素在润湿和解吸过程中的超分子重排特征

考虑到在其结构元件之间存在狭缝状孔的系统，提出了棉纤维素结构的模型。使用1H-NMR光谱，吸附和解吸测量，可以确定水合棉纤维素孔壁的比表面积。显示了在润湿的不同阶段纤维素的结晶度及其晶间孔的比表面积变化的性质。发现在吸附-解吸过程中多孔体系对结晶度为0.7的棉纤维素的总比表面积的贡献不超过70％。
