SWCNT/PEDOT:PSS/SWCNT composite cotton texture is set up by coating technique as portrayed[ FIG5.1] Composites of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) and single-wall carbon nanotube (SWCNT) were set up by blending of PEDOT:PSS and SWCNT that blend with deionized water (DI) for 45min by by tip sonicator at various weight proportions and .5ml DMSO was included for 30 min at room temperature, The Cotton texture was dunked into the SWCNTs arrangement utilizing Drop casting technique for 35MIN and drying at temperature 100?C FOR 60MIN.carbon nanotube (SWCNT)/Poly (3,4 ethylenedioxythiophene)poly(4-styrenesulfonate) (PEDOT:PSS)/SWCNT composite texture are set up by covering system.The stacking rate of SWCNTs in the host polymer is upgraded to improve the conductivity of the polymer without compromising the transparency of PEDOT:PSS.
characterization Method
So asto research the electrical properties of the conductive cotton textures, a gold four-line test method was utilized as per the writing. Electrical resistances of the pure cotton were determined from I-V bends at temperature 25C . The sheet resistance was determined from the equation R_s=R(w/d) where w is the width of the example (2.5 cm) and d is the separation
conductive system on the microfiber surface.The composite (swcnt\pedot:pss\swcnt)2 multilayer gave the most noteworthy conductivity SWCNT that is fused into PEDOT:PSS is advanced to get a low Sheet Resistance of Conductive Cotton Fabrics.The sheet obstruction of the DETE test diminishes () as the fixation increments from () Theses changes in the estimations of sheet opposition are credited to the auxiliary dopant (DMSO) instigating morphological changes, for example, expanding PEDOT-rich grains and producing a more slender PSS hindrance by specifically expelling PSS from the PEDOT:PSS film prompting better charge transport pathways and associations between PEDOT-rich grains.This might be ascribed to the SWCNT\ PEDOT:PSS \SWCNT forming layers on the strands and filling the space between them the fabric .The effectiveness of cotton as a conductive texture might be estimated by the measure of SWCNT\ PEDOT:PSS\SWCT important to deliver givenFurthermore, DMSO can likewise go about as a plasticizer reorienting PEDOT as well as PSS fastens at high temperatures to shape a profoundly conductive permeation organize by improving associations between directing PEDOT chains[25] .Including a little measure of PEDOT:PSS makes the cotton change to a leading state because of the arrangement of associated PEDOT:PSS chains on the cotton fabric .ectrical qualities (Table 5.3 )[ Fig 5.6] delineates two particular locales.In district 1, the (logarithm of) sheet obstruction diminishes as the grouping of PEDOT:PSS increments.In district 2, the high fixation area, the sheet resistance of the cotton tests is diminished strongly when concentration of dopant is increased the centralization of dopant is expanded to its immersion level.The sheet resistance of conductive cotton textures was examined for pure cotton as appeared in Figure X. All examples have territory 1 x 1inch ,the pure cotton is thickest.As appeared in Figure X, The pure conductive cotton shows a comparable pattern as an element of fixation.The reason may be that high electron versatility and electrical conductivity along the carbon nanotubes give more efficient electron exchange.Estimations were performed at room temperature utilizing the four-line test technique.
STest methods
Interconnection resistance. Electrical resistance measurements,were performed using a multimeter () in a four-wire resistance mode and a four-point probeFigure 2.
Piezoelectric effect
The gloves were worn by a test subject and the conductivetracks were connected to an oscilloscope tracks were connected to an oscilloscope.This gave a rough estimate of the
electrical performance of the different sample gloves The same gloves were tested repeated times during the same measurement and the tests were repeated several weeks after the first measurements, all giving similar results
Temperature Dependence
The temperature reliance of pure cotton was estimated from( 25 to 100) 0C at focusespure cottons () wt.% as appeared in [Fig] pure cotton showed a comparable trend; This conduct might be ascribed that to the formation of charge localization because of the making of creation issue in the structure of SWCNT\PEDOT:PSS causing shortening of its conjugation length. . The metallic conduct saw in this investigation might be because of the high consenteration of polymer AND SWCNT implanted in the pure cotton sample .The stability OF Temperature of the conductive cotton fabric a t ()Wt% was also investigated over a period of four months and found to be stable
Electrical Stability of Sheet Resistance
Electrical stability of the conductive pure cotton example (wt.%),was assessed by observing the sheet resistance at room temperature over a time of three months as appeared in [Fig] test indicated great electrical stability security in light of the fact that their estimations of sheet resistance remained generally steady amid this timeframe

The thermal behavior of the treated,untreated pure cotton and SWCN \ PEDOT:PSS
The thermal conduct of the control sample and SWCN \ PEDOT:PSS treated cottons was examined utilizing thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC).This improvement in the thermal stability could be ascribed to the arrangement of formation of hydrogen bonding between the PEDOT:PSS \SWCNT chains and the cotton textures.The thermal steadiness of SWCNT\ PEDOT:PSS is stretched out to the range 400-480 oC when it is utilized in impregnated cotton textures.The TGA thermograms of the untreated cottons demonstrate that thepure cotton example are thermally steady for temperature underneath 346oC .
The DSC thermogram showed endothermic pinnacles comparing to the melting point of the treated and untreated pure cotton textures swcnt\pedot:pss composites with 10 and 30 wt% loadings are thought about in [Fig5.13B] The control was 92 C, while the example containing 30 wt% of SWCNTs\pedot:pss is noted at 100 C and the example containing 10 wt% of SWCNTs\PEDOT:PSS does not demonstrate much variety from the control test. The for cotton did not have melting peak with any of these examples up to 250 C[17].
Washability
The durability to laundering of the printed samples washing procedure with detergent
and line drying, in a laboratory washing machine washed samples were evaluated with electrical resistance measurementsResults and discussionDesign of the sensor glove
The gloves were studied as a proof-of-concept, as illustrated in Figure 3, with the overall purpose of validating the electrical function of the textile approach.The hand configurations can be assessed by individually measuring the output resistance of the sensors.In order to characterize the printed interconnectionsseparately, samples were prepared by DROP CASTING defined areas of the interconnection material on the fabric To demonstrate the potential use of the SWCNT\PEDOT:PSS \SWCNT compositesas strain sensors in wearable devices for detection of human activities, a data glove was assembled by integrating independent SWCNT\PEDOT:PSS sensors on each joint, as shown in
Fig.Assuch, the focus was to test whether the 100% polymer \cnts based textile electronics remained true to their function In order to verify this, it was considered sufficient to limit the amount of sensors to one per finger and thesensing confined to the movement of entire fingers,where the greatest strain in the glove occurs just overthe knuckles
Electrical resistance as function of geometry ofinterconnections For obvious reasons, it was preferable that the printedinterconnections were as narrow as possible on the glove.Devices with SwCNT strain sensors might be used to recognize human motion and automatically translate sign language.().
Conclusions
This paper has presented a study of a motion sensing entirely polymer \SWCNT-based glove with possible applications in physical rehabilitation. Important aspects of the glove were the textile production methods utilizing all-polymeric \SWCNT, safe and readily available functionalmaterials as well as the possibility of the glove remainingcomfortable and durable throughout use interconnections was shown to be a reliable method . The screen-printing of conductive PEDOT:PSS \swcnt .
