Description
Background technology
Organic porous polymer (Porous Organic Polymers, POPs) is made up of atoms such as carbon, nitrogen, oxygen, hydrogen
A kind of new material with high-specific surface area, developed pore structure, low skeletal density and excellent stability, according to forming hole
The reason for can be divided into five classes again：Covalent organic framework material (Covalent Organic Frameworks, COFs), conjugation are micro-
Pore polymer (Conjugated Microporous Polymers, CMPs), super cross-linked polymer (Hyper-Crosslinked
Polymers, HCPs), inherent porous polymer (Polymers of Intrinsic Microporosity, PIMs) and ethene
Base functionalized polymer etc..
Covalent organic framework polymer (Covalent Organic Frameworks, COFs) typically by covalent bond (C-C,
C-O or B-O etc.) the rigid construction unit of connection, a kind of ordered crystal structure is obtained under the reversible reaction of balance controlled
POPs.It is typically transition metal-catalyzed to be conjugated microporous polymer (Conjugated Microporous Polymers, CMPs)
Under autoimmunity syndrome or cross-coupling reaction obtain.From tool microporous polymer (Polymers of Intrinsic
Microporosity, PIMs) it is due to that itself rigidity and the nonplanar structure distorted cause strand spatially can not be close
Accumulate and form a kind of special polymer of micropore.Super cross-linked polymeric (Hypercrosslinked Polymers, HCPs) is most
Found before this in the synthesizing porous polystyrene network structure of Friedel-Crafts alkylated reactions, such material has higher
Specific surface area, but the shortcomings of HCPs pore-size distribution is relatively wide, and preparation condition is stricter, cause its application still to be limited at present
In adsorbing separation field.
In above-mentioned material, COFs chemical stability is poor；Reaction condition is harsher, and operation difficulty is larger；HCPs its
Cross-linking reaction occurs at random, causes the regularity of material internal microporous network low；CMPs and PIMs manufacturing cost is high, reacts bar
Part is harsh.
The technology of the present invention；After microballoon is accumulated, carry out super cross-linking reaction and greatly reduce the chemistry dirt as caused by multiple operation
Dye problem；Its superior performance, after adding the polymer as microsphere adhesive, material shape is complete, good toughness；It is manufactured
Cost is cheap, can form the various shapes porous materials such as large-sized bar-shaped, sheet material shape, bulk, there is good industrial prospect.
The content of the invention
A kind of technique of present invention offer is simple, the preparation method of the cheap porous styrene materials of cost, including：
(1) solvent (mass ratio 0 configured in absolute ethyl alcohol and deionized water:100-100:0) second containing phenyl ring is added
Alkenyl monomer, such as styrene；Double bond containing comonomer：Such as dimethyl diallyl ammonium chloride (DMDAAC), metering system
Sour hydroxyl ethyl ester (HEMA), MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chloride (DMC) etc.；Initiator：Such as azodiisobutyronitrile, peroxide
Change dibenzoyl etc.；Stabilizer：Such as polyvinylpyrrolidone, polyvinyl alcohol；Crosslinking agent：Such as divinylbenzene；Stirring, constant temperature are anti-
Should, temperature is about 70-80 DEG C, obtains styrene copolymerized microballoon；
(2) by the polymer of the styrene copolymerized microballoon and opposite charges that prepare (such as the polymer of positively charged：Poly- second
Alkene imines etc. is birdsed of the same feather flock together compound containing ammonium；Electronegative polymer：Polyacrylic acid, polymethylacrylic acid etc. tire out polymer containing carboxylate radical)
Solvent (such as：Water, ethanol) in be well mixed
(3) pour the mixture into the container (such as flat shallow container, rod-like container, block-shape vessel etc.) of smooth and clean,
Treat that microballoon settles, solvent natural evaporation, obtain polystyrene material；
(4) the styrene film obtained by step 2, anhydrous ferric chloride, dimethoxymethane (FDA) are added to 1.2- dichloros
In the solvent of ethane, polystyrene porous material is made.
The advantages of the technology of the present invention：
1st, using styrene and dimethyl diallyl ammonium chloride as raw material, preparation cost, and quaternary ammonium salt energy are greatly reduced
Combined with carbon dioxide, improve the adsorption capacity of material silica carbon.
2nd, the addition as the polymer for bonding and assigning toughness of material, can make porous material obtain different performances.
2nd, porous material precursor is prepared with natural sedimentation, then surpasses and be cross-linked to form porous material.Reduce material preparing
During the caused chemical contamination due to multiple operation.
3rd, equipment requirement is relatively low, can prepare different shape, various sizes of porous material according to different vessels.
4th, it is easy to industrialized mass production and application.
The present invention is prepared for that a kind of technique is simple, the cheap carbon dioxide absorber of cost.The adsorption operations are simple, application
Extensively, it may extend to industrial production.
