Description
Technical field
The present invention relates to field of fine chemical, and in particular to a kind of carbon nano-fiber surface modification method.
Background technique
Theoretical and experimental study all shows that carbon nano-fiber is a kind of high intensity 95% or more of phosphorus content, high-modulus
Carbon material, have the characteristics that high specific strength, superhigh temperature resistant, endurance, good conductivity.So carbon nano-fiber is as polymerization
There are very big potentiality with modifying agent aspect in object matrix.But the dispersibility of carbon nano-fiber in a polymer matrix is always
It is that it is hindered to obtain high performance critical issue.Carrying out surface treatment to carbon nano-fiber is the important side for improving its dispersibility
Method, physical method and chemical method can be divided at present by dividing by technique the surface treatment of carbon nano-fiber.The former mainly includes
Coating and plasma processing, the latter mainly include surface oxidation method, electrochemical process and Graft Method.
But usually used carbon nano-fiber surface modification method is haveed the defects that: using surface oxidation
The chemical treatment methods such as method can make carbon nano-fiber bend, kinking, fracture, destroy its structure, so that nano-sized carbon
The performance of fiber declines, while largely using strong oxidizer, so that the waste liquid after processed is difficult to handle, and generates when reaction
Pollution gas larger harm can be caused to environment.And single non-covalent modification method is used, although will not be to nano-sized carbon
The structure of fiber damages, and less pollution, but its dispersion effect is poor compared with covalent modification.
Summary of the invention
In order to be destroyed carbon nano-fiber not in structure, with stable dispersibility while keeping complete performance, this
Disclosure of the invention a kind of carbon nano-fiber surface modification method, this method are suitable for polyacrylonitrile-based carbon fibre and asphaltic base simultaneously
The surface treatment of carbon fiber.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of carbon nano-fiber surface modification method, includes the following steps:
(1) first step pretreatment of carbon nano-fiber: carbon nano-fiber is obtained by untreated, at low temperature plasma instrument
Reason handles time 10s~90s, processing power 100W~300W.After reaction, the carbon nano-fiber after will be processed remains
Second step processing；
(2) cladding processing is carried out to step (1) processed carbon nano-fiber with poly-dopamine: by trihydroxy methyl amino first
Alkane and hydrochloric acid solution are uniformly mixed, and the mass ratio of hydrochloric acid is 10~20:1 in the trishydroxymethylaminomethane and hydrochloric acid solution,
It is diluted with water, is configured to the Tris buffer solution that solid content is 0.5%~1.5%, it will be through step (2) processed Nano carbon fibers
Dimension is added in Tris buffer solution with poly-dopamine powder, in stirring on magnetic stirring apparatus.
Wherein the carbon nano-fiber and the mass ratio of poly-dopamine are 1:0.1~3, and carbon nano-fiber buffers molten with Tris
The ratio of liquid is that every 0.1g carbon nano-fiber needs 50~200mL of buffer solution.It is by adjusting three hydroxyl first that PH is adjusted in this step
Base aminomethane and hydrochloric acid ratio are realized.
(3) coupling modification is carried out to step (2) processed carbon nano-fiber with coupling agent: coupling agent is dissolved in anhydrous second
In alcohol, 0.025~0.15g containing coupling agent in every liter of dehydrated alcohol is stirred evenly, to step (2) mixing time 12-60h
Afterwards, the ethanol solution containing coupling agent is added, continues 1~12h of stirring, using deionized water filtering and washing to neutrality, rear Yu Zhen
It is dried in empty drying box.
The carbon nano-fiber and coupling agent mass ratio are 100:0.5~3, the volume ratio of ethyl alcohol and water is 10%~
90%.
Coupling agent is added after step (2) stir a period of time to be further improved, if by changing again after step (2) drying
Property, drying course can cause damages to the activity of raw material.
Preferably, above-mentioned steps (2) trishydroxymethylaminomethane and hydrochloric acid mass ratio are 13~15:1, add water dilute
It releases, is configured to the Tris buffer solution that solid content is 0.5%~1%.Adjust proportion be in order to adjust PH, and PH will affect it is poly- more
The formation of bar amine.
Preferably, above-mentioned steps (3) coupling agent is Silane coupling agent KH550, KH560, KH570 or A171.It is preferred that
A171；While improving compatibility, double bond therein can be participated in into methyl vinyl silicone rubber silane coupling A 171
Vulcanization improves the degree of cross linking, can be further improved the performance of material.
The present invention first carries out corona treatment and is on the one hand to be conducive to subsequent and poly-dopamine combination, another party
The decomposition temperature of poly-dopamine is improved, avoids adding in high temperature by improving the binding ability between carbon fiber and poly-dopamine in face
Reduced performance caused by the decomposition of poly-dopamine during work；Introducing hydroxyl also in carbon fiber surface after corona treatment has
Conducive to the absorption of coupling agent.There is conspiracy relation between each other.
The composite modified method of using plasma of the present invention processing, polymer overmold and coupling agent treatment is to nano-sized carbon
Fiber is surface-treated, pollution-free, safe, easy to operate compared with the methods of usually used nitration mixture processing, this case modification
Carbon nano-fiber afterwards in a solvent can stable dispersion, and with the compatibility of polymer improve.
