Hydrophobic coatings on cellulosic materials were obtained using triethoxy(octyl)silane and its dimer, 1,1,3,3-tetraethoxy-1,3-dioctyldisiloxane, as modifiers. The structures of the modifiers were studied. The efficiency of the use of these modifiers in producing hydrophobic coatings was demonstrated. The maximum contact angle of 135° is achieved with a modifier content not exceeding 8% and with coating thickness of only 4 um or less. The modified materials retain their hydrophobic properties for a long time.

基于三乙氧基（辛基）硅烷的疏水涂层

使用三乙氧基（辛基）硅烷及其二聚体 1,1,3,3-四乙氧基-1,3-二辛基二硅氧烷作为改性剂，在纤维素材料上获得疏水涂层。研究了改性剂的结构。证明了使用这些改性剂生产疏水涂层的效率。改性剂含量不超过 8% 且涂层厚度仅为 4 um 或更小，可实现 135° 的最大接触角。改性材料长时间保持其疏水性。
