Abstract:The feature of superhydrophobic material surface is micro-nano structure coated with low surface energy substance.The prepared CNC was spray-dried to obtain micro-nanoparticles（CNCmp）， which was modified by chemical vapor deposition using MTMS.The modified CNCmps were used to prepare superhydrophobic coatings， and sprayed on the filter paper to form super-hydrophobic-filter-paper.The silanization reaction was critical for superhydrophobic coatings preparation.It was found that the amount of MTMS used in the silanization reaction in a designed device was optimized as 70 μL， the reaction temperature was 25℃， and the reaction time was 10 min. Silane modified micro-nanocellulose particles could be used to prepare superhydrophobic coatings.It was also found that there was no difference for the superhydrophobic materials prepared by modification using fluorosilane PFOTES and MTMS．
