PEDOT:PSS/GO NANOCOMPOSITE FOR INDOOR CO2 SENSOR

Carbon dioxide (CO2) which is a colourless and odourless gas, requires an efficient detection, as excessive amount in the environment would possibly leads to global warming. This work discusses on environmentally friendly non-toxic CO2 sensor for indoor air monitoring. The fabricated developed by using poly(3,4ethylenedioxythiophene):poly(4styrenesulfonate)/ graphene oxide (PEDOT:PSS/GO) nanocomposite. Nanocomposite characterisations are performed field-emission scanning electron microscope (FESEM) X-ray diffraction (XRD) confirm excellent properties of PEDOT:PSS GO suitable materials development. Fabrication one layer PEDOT:PSS/GO nanocomposite kaolin-coated paper substrate via dip coating method shows good electrical conductivity 0.25 S. At room temperature, at fixed flow rate 0.05 l/min, response time 32 s, with sensitivity 0.8 16/l/min respectively. With fast chemiresistive towards molecules, provides promising results
