Specific embodiment
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, according to normal conditions or manufacturer builds
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
A kind of composite conducting fiber of the embodiment of the present invention and preparation method thereof is specifically described below.
A kind of preparation method of composite conducting fiber provided in an embodiment of the present invention, comprising the following steps:
S1 prepares silk fibroin protein solution.
Further, the preparation method of the silk fibroin protein solution includes the following steps:
S11 puts into the sodium bicarbonate solution that mass fraction is 0.5%~1% after silk cleans and carries out degumming, floats
Wash, dry after obtain fibroin fiber.Further, the silk after removal of impurities is placed in the bicarbonate that mass fraction is 0.5%~1%
In sodium solution, 60~90min of degumming under the conditions of 60~100 DEG C then obtains fibroin fiber by rinsing, baking step.
S12: the fibroin fiber is placed in lysate and dissolves, obtain initial silk fibroin protein solution after filtering.
Further, the lysate is selected from one of lithium-bromide solution, calcium chloride solution, formic acid, and the fibroin
Solution temperature of the fiber in the lysate is 40~60 DEG C, and dissolution time is 4~6h.Preferably, of the invention preferably real
It applies in example, the LiBr solution of 9.0~9.5mol/L is selected to dissolve fibroin fiber.
S13 dialyses in ultrapure water after the initial silk fibroin protein solution is placed in bag filter, obtains pure silk
Fibroin solution.Further, the molecular cut off of the bag filter is 3500~8000kDa, and initial silk fibroin protein solution exists
It dialyses 2~3 days in ultrapure water.
S14, the pure silk fibroin protein solution is counter in anti-dialyzate to be dialysed after centrifugation and filtering, obtains matter
Amount score is 20%~40% silk fibroin protein solution.Further, the anti-dialyzate is mass fraction 10%~20%
PEG20000 solution.
By being dialysed to silk fibroin protein solution is counter, the silk fibroin protein solution that mass fraction is 20~40% is obtained, really
Possessing sufficient concentrations of fibroin albumen can be combined with multi-walled carbon nanotube, guarantee during subsequent wet spinning, spin
Silk liquid can be rapidly solidificated into fiber.
The silk fibroin protein solution is mixed with multi-walled carbon nanotube solution, obtains spinning solution by S2；Wherein, the spinning
The mass ratio of fibroin albumen and multi-walled carbon nanotube is 1:0.1~0.35 in liquid.It is further preferable that fibroin albumen is received with multi wall carbon
Mitron mass ratio is 1:0.2~0.35.Under this ratio, composite conducting fiber prepared by the present invention not only has good stretching
Ability, and have good electric conductivity, and inventor also found when multi-walled carbon nanotube content is lower than the content of fibroin albumen
10%, then be unable to get the composite fibre for having electric conductivity.And when multi-walled carbon nanotube content is higher than the content of fibroin albumen
35%, the multi wall carbon mitron of too high levels is easy to reunite in the silk fibroin protein solution of high concentration, leads to fibroin albumen
With multi-walled carbon nanotube incomplete mixing, and post-stretching step can not be carried out.
Further, the mass fraction of the multi-walled carbon nanotube solution is 5%-10%.With the multi wall carbon under this concentration
Nanotube solution is mixed, and is avoided in mixed process, solution because generating aggregation, deposition containing excessive multi-walled carbon nanotube,
The spinning solution multi-walled carbon nanotube prepared and fibroin albumen is caused to disperse uneven, to influence subsequent step.
Further, the silk fibroin protein solution and multi-walled carbon nanotube solution mixing step are as follows: be by mass fraction
The multi-walled carbon nanotube solution of 5%-10% be directly added into mass fraction be 20~40% silk fibroin protein solutions in, then slowly into
Row turns upside down after mixing, obtains spinning solution after carrying out centrifugation bubble removing to mixed liquor with the revolving speed of 1000rpm.In this mixing step
In rapid, ultrasonic mixing and fierce concussion mixing not can be carried out, the fibroin albumen property of high concentration is unstable, in mixed process easily
Plastic is solidified, silk fibroin protein solution is eventually led to multi-walled carbon nanotube solution and mixes unevenness, influence the system of composite conducting fiber
It is standby.
The spinning solution is injected into solidification in coagulating bath using wet spinning technology and obtains as-spun fibre by S3, described first
Raw fiber is via stretching, obtain composite conducting fiber after steam treatment.
Wet spinning technology is that spinning solution is dissolved in solvent, sprays thread by spinneret orifice, forms fibre into coagulating bath
The chemical fibre spinning method of dimension.In an embodiment of the present invention, coagulating bath is in methanol, ethyl alcohol, saturated ammonium sulfate solution
One kind, coagulating bath can be such that the fibroin albumen in spinning solution solidifies.
Further, the coagulating bath is placed in the container that a length is 1.5~2m, it is ensured that when having enough solidifications
Between solidify spinning solution.
Further, the composite conducting fiber is via 2~6 that the length after stretching step is the as-spun fibre length
Times.Because of the design feature of multi-walled carbon nanotube, as-spun fibre is stretched to suitable length, peomotes multi-walled carbon nanotube
Orientation is neat, facilitates the electric conductivity of product.And to as-spun fibre stretching transition, it is fine to will lead to the composite conducting being prepared
Tie up easy fracture；Conversely, stretching is insufficient, then it will affect electric conductivity.
Further, the as-spun fibre after stretching needs to carry out steam treatment, the steaming step are as follows: 40~60
2~6h of steam treatment under the conditions of DEG C, wherein the steam is water vapour or alcohol vapour.Steam treatment can composite conducting fiber mention
High-crystallinity keeps the composite conducting fiber after stretching not easy to break to enhance the intensity of composite conducting fiber.
Further, the diameter of the composite conducting fiber is 10~40 μm, is conducive to composite conducting fiber to weave
Mode be woven into fabric, the development for following intelligent textile garment, intelligent flexible wearable electronic device lays the foundation.
The present invention also provides a kind of composite conducting fibers, are made according to above-mentioned preparation method.Composite conducting obtained is fine
Dimension has given up the method that conductive material is coated directly on fiber, by by fibroin albumen and multi wall carbon compared with prior art
Nanotube is combined on a molecular scale, is guaranteed that multi-wall carbon nano-tube tube particle is not easily to fall off and is fallen off from composite conducting fiber,
Ensure the maintenance of composite conducting fiber electric conductivity.And composite conducting fiber has both silk because of the fibroin albumen with high-content
It while the flexibility and biocompatibility of fiber, and include the multi-walled carbon nanotube of high concentration, it is ensured that composite conducting fiber
With good flexibility and electric conductivity.The present invention has widened the application range of silk fiber, is conducive to that the following intelligence is pushed to spin
