Study on Chemical Vapour Sensing Property of Esterified Poly(vinyl Alcohol)

Abstract:

Article Preview

Modification of poly(vinyl alcohol) (PVA) by esterification is one of alternative ways to prepare copolymers. The degree of esterification on PVA was determined by FTIR, 1H-NMR, and elemental analysis. Both polymers, i.e., PVA and esterified PVA were mixed with carbon black in DMSO and prepared as thin films onto the interdigited electrodes (IDE) by spin-coating technique to obtain chemical sensors. To investigate the chemical vapour sensing property, the chemical sensors were examined with various organic solvents such as hexane, toluene, alcohols, THF, ethyl acetate, etc.
