Fabrication of SWCNT/PVA composite fiber using wet spinning:
SWCNT/PVA solution is extruded into coagulant using surfactant SDS, and air-dried
to make fiber (with tensile strength of 750 MPa)
The fiber swells upon moisture absorption, resulting in wider gap in SWCNT and rapid
increase of electrical resistance. Humidity is sensed by measuring the resistance change
Applicable to wearable textile thanks to high tensile strength and washability
