Actual application value.[Ramezani M, Vaezi M R, the Kazemzadeh A. such as Maedeh RamezaniApplied Surface Science, 2014, 317(2):147-153.] using ethyl triethoxysilane as presoma, ethanol is molten
Agent, ammoniacal liquor is that SiO has been made in catalyst2Colloidal sol, substrate glasses piece is immersed in colloidal sol, the sheet glass various concentrations of drying
Iso- trimethoxy silane/ethanol solution carry out hydrophobic silanization modification, the water contact angle of obtained super hydrophobic surface is up to
160°.[Pham V H, the Dickerson J H. such as DickersonAcs Applied Materials & Interfaces,
2014, 6(16):14181-14188.] melamine foams are carried out with trichlorine octadecylsilane by solution infusion method it is hydrophobic
It is modified, its surface tension is reduced to increase the hydrophobicity of material surface.The water contact angle of the modification foam finally obtained is
151 °, with superhydrophobic characteristic.The experiment of its Oil ＆ Water shows that the saturated absorption capacity of modified foam is distributed in more than 80 times certainly
Body weight, and repeatedly circulation water-oil separating can be realized by absorption/extrusion cycle, during 1000 circulation experiments always
Keep excellent saturated absorption rate.[Wang X, Xu S, Tan Y, the et al. such as WangCarbohydrate Polymers, 2016, 140(20):188-194.] utilize hexadecyl trimethoxy silane（HDTMS）By sol-gel
Method prepares silanization microcrystalline cellulose（MCC）, the porous hydrophobic cellulose composite material of synthesis can be used for high efficiency oil-water separation,
And up to 99.77% water-oil separating efficiency is maintained to after 10 uses of circulation.
But the above hydrophobicity sponge the problem of can face many in actual applications, such as prepared by complicated processing
Process, expensive experiment reagent and equipment, material reusability be poor, in preparation process with secondary pollution etc..Especially this
A little modified sponge overwhelming majority are using materials such as polyurethane and melamine resins as template, and its template preparation process can generation environment
Pollution.Although the reusing of sponge is good, its recyclable power of regeneration is poor, is especially difficult to drop in natural environment
Solution, does not meet the concept of Green Chemistry and the trend of era development.This patent commodity in use ethyl cellulose, passes through one kind warp
Hydrophobic ethyl cellulose sponge is made in efficient, inexpensive, the free of contamination preparation technology of Ji, by be crosslinked and introduce CNT come
Collaboration enhancing sponge matrix, resulting hydrophobic three-dimensional porous sponge has preferable stability, oil absorption, synthetic operation letter
Single, good industrialization production feasibility, it is possible to achieve produce in enormous quantities has good application in marine oil pollution processing procedure
