Description
Technical field
The invention belongs to functional living being material development field, relate generally to a kind of super-hydrophobic wood fibre powder and
Preparation method.
Background technique
Wood fiber biomass is the organic matter that photosynthesis generates.Green plants utilizes chlorophyll will by photosynthesis
Solar energy is converted into chemical energy and is stored in wood fiber biomass, by certain method, that is, produce it is a kind of it is environmental-friendly,
Reproducible low-carbon energy has many advantages, such as that source is wide, rich reserves, renewable, low pollution, and wood fiber biomass is deposited extensively
It is in nature, main component is cellulose, hemicellulose and lignin.
Wood fiber biomass raw material have phosphorus content is high, ash content is low, abundance, it is renewable, from a wealth of sources, cheap easily
The features such as obtaining becomes the presoma of many materials preparations.Such as sawdust, almond, oil tea shell, peanut shell, cocoanut shell, corncob can
As the raw material for preparing active carbon；Using wood fiber biomass such as Semen sesami nigrum, black fungus, seaweed, mushrooms as precursor preparation carbon
Nanotube；In addition, researcher grows stone in nickel sheet and Cu foil using weeds, plastics, petal, bagasse, newspaper as presoma
Black alkene.Its recycling, high-valued and commercialization can effectively be realized by preparing a variety of materials as raw material using wood fiber biomass, no
Production cost can also be effectively reduced by being only capable of economizing on resources, while can also reduce the pollution to environment.
In recent years, due to the oil pollution accident frequently occurred, so that oily pollution becomes the global environment being concerned and asks
Topic, therefore be badly in need of developing a kind of method for separating/removing water pollutant.Super hydrophobic material is a kind of big with water contact angle
In the material for being equal to 150 °, since it is with super-hydrophobic super-oleophylic characteristic, so that it has fabulous answer in water-oil separation field
Use prospect.The big surface area of three-dimensional porous material and surface roughness make it have preferable absorption power in adsorption process
It learns, adsorption equilibrium can be reached faster, can be used as a kind of potential material of oil adsorbent.Three-dimensional porous structure super hydrophobic material is not
Only huge memory space can be mutually provided for oil, be that can reach the mutually quick separation of the oil of absorption by mechanical presses, be convenient for it
It recycles.Therefore, how to carry out simple, easy-operating modification and prepare super hydrophobic material and become to want in three-dimensional porous material substrate
The main problem of solution.
By super hydrophobic surface construction on netted or porous material, water-oil separating may be implemented, this is controlling or is mitigating
Caused marine pollution aspect is frequently revealed by petroleum and shows huge application potential, efficiently contributes to protect the marine environment
With the sustainable development for pushing marine industries.However, at present super hydrophobic material preparation technique and in the process there is also one
A little problems: most of super hydrophobic material is low using the progress of fluorinated chemical substance to its surface in order to improve its ultra-hydrophobicity
Surface can be modified, its cost is substantially increased；Many super hydrophobic material preparation steps are complicated, and preparation condition is harsh, manufacturing cycle
It is long；And super hydrophobic material surface its ultra-hydrophobicity under extraneous environmental activity is subject to destroy.Problems above restricts
Practical application of the super hydrophobic material in water-oil separating field, therefore cheap raw material, simple preparation process, surface be strong
Mechanical stability will be the following research hotspot for preparing super hydrophobic surface.
To sum up, wood fiber biomass raw material is as a kind of cheap and easy to get, abundance, reproducible bulk multi-hole material
Material has the possibility for preparing hydrophobic material；The preparation process of existing super hydrophobic material is complicated, and higher cost, the period is long, and its
Ultra-hydrophobicity is unstable.On this basis, we organically combine hydrophobicity and wood fiber biomass raw material, prepare excess of export
Hydrophobic wood fiber biomass material, it will the application for further widening wood fiber biomass raw material improves its economy
Value, while helping to solve the problems such as hydrophobic material is at high cost, preparation process is complicated.
