Method.Table 1 is obtained by above-mentioned detection,
The performance of 1 graphene conductive fabric of table
As it can be seen from table 1 embodiment 1 and comparative example 1 and the comparison of comparative example 2 as can be seen that fabric by alkali process and
After supercritical carbon dioxide treatment cooperation, the graphene conductive fabric finally obtained is in the case where washing times are more, water
Wash that fastness is still fine, and the sheet resistivity before washing and after washing is smaller, graphene sheet layer structure more enters swelling
Fabric and swelling gap in, after washing, the changing value of sheet resistance is smaller, and graphene-supported fastness is preferable, makes stone
The functional characteristic of black alkene conductive fabric can preferably be brought into play, and washing fastness is high.

Swollen and etching, graphene slurry can not be well bonded on fabric, and the functional characteristic of conductive fabric is bad, and washing fastness is not
It is high.
For embodiment 1 as can be seen that the temperature of alkali process is excessively high compared with comparative example 6, fiber surface etching can be more serious,
Fiber surface forms defect, and in the process of washing, fiber itself has the fracture of partial extent and falls, and seriously affects washing
Fastness keeps washing fastness lower.
Embodiment 1 and embodiment 2 compare it is found that first carry out calendering, carry out supercritical carbon dioxide treatment afterwards, make graphene
The functional characteristic of conductive fabric plays more preferable.
Embodiment 1 and embodiment 3 compare it is found that without calendering processing before supercritical carbon dioxide treatment, make graphite
The functional characteristic performance effect of alkene conductive fabric is bad, and washing fastness is not high.Illustrate, before supercritical carbon dioxide treatment not into
Row calendering processing, the swelling effect of fabric are bad.
From embodiment 1 and embodiment 4 as can be seen that the different types of fabric of selection, also can be used provided by the present application
Method is swollen fabric, more preferable to play the functional characteristic of graphene conductive fabric.But different fabric types warps
It crosses after identical processing, the effect of swelling has certain difference.
Embodiment 5 and embodiment 6 are as can be seen that use the dispersing agent for containing nonionic and anion as graphene slurry
Dispersing agent, keep the dispersion effect of graphene slurry good, graphene can preferably be embedded in the inside of the fabric after swelling and empty
In gap, play the functional characteristic of graphene conductive fabric more preferable.
If from embodiment 1, embodiment 7-9 can be seen that graphene sheet layer structure size and piece diameter it is excessive, graphene
Even if being supported on the surface of fabric, after washing, can also fall off, washing fastness is bad, the function of graphene conductive fabric
Energy characteristic can not be brought into play.
It can be seen that functional characteristic of the temperature to graphene conductive fabric of alkali process from embodiment 1, embodiment 10-11
Performance have it is certain influence, illustrate that the temperature of alkali process has a certain impact to the swelling effect tool of fabric, it is too high or too low
It will affect the swelling effect of fabric, and will affect the washing fastness of fabric.
From embodiment 10-11, comparative example 1-2 can be seen that alkali process temperature be 50 DEG C or 75 DEG C when, compared to independent
Alkali process or individual supercritical carbon dioxide treatment for, washing fastness is higher, and sheet resistance is smaller, illustrates at alkali
When the temperature of reason is 50 DEG C or 75 DEG C, alkali process and supercritical carbon dioxide treatment can still play preferable synergistic effect,
The performance of the graphene conductive fabric made is more preferably.
It can be seen that functional characteristic of the concentration to graphene conductive fabric of alkali process from embodiment 1, embodiment 12-13
Performance have it is certain influence, illustrate that the concentration of alkali process has a certain impact to the swelling effect tool of fabric, it is excessively high it is too low
It will affect the swelling effect of fabric, and will affect the washing fastness of fabric.
Experimental example 3
After fabric cleaning, immerses in the sodium hydroxide solution that mass concentration is 25g/L, be warming up in 70 DEG C of water, protect
Warm 30min takes out washing drying and obtains sample 1；After fabric cleaning, it is molten to immerse the sodium hydroxide that mass concentration is 15g/L
It in liquid, is warming up in 70 DEG C of water, keeps the temperature 30min, take out washing drying and obtain sample 2.SEM is carried out to sample 1 and sample 2 respectively
Electronic Speculum measurement, obtains SEM shape appearance figure such as Fig. 3 of sample 1, SEM shape appearance figure such as Fig. 4 of sample 2.Fig. 3 and Fig. 4 comparison can be seen
Out, after the aqueous slkali of low concentration handles fabric, swelling action can not be played；The aqueous slkali of high concentration to fabric into
After row processing, swelling action can be played, and the epidermis of fiber can be stripped, generate peeling phenomenon, the surface quilt of fiber
It etches away, fibrous inside is exposed, and is conducive to and the combination of graphene slurry.
