Using MCM-41 as a carrier,the silane coupling agent 3-chloropropyltrimethoxysilane(CPTMS) was grafted onto MCM-41 molecular sieve by post-grafting method to prepare functionalized MCM-41-Cl as a new type of super-hydrophobic material.The structure was determined by FT-IR.Malvern laser particle size analyzer,SEM,and the performance was evaluated by an experiment such as a contact angle measuring instrument.The results showed that CPTMS was successfully grafted onto MCM-41.The contact angle of functionalized MCM-41-Cl with water was 157.9°.It was a molecular sieve-based super-hydrophobic material,and MCM-41-Cl was investigated for different oil products.And the organic solvent reached the oil absorption rate when the oil was saturated.It was found that the oil absorption rate of MCM-41-Cl to toluene was as high as 290.98%,showing a good super-hydrophobic oil absorption performance.
