“…Another sensing mechanism for conducting polymer/graphene hybrids was proposed by Konwer et al [102], who prepared a polyaniline/GO (PANI/GO) hybrid and investigated its sensing properties to methanol. It was proposed that the change in conductivity of the hybrid was caused by the strong hydrogen bonding between methanol and PANI, which disrupted the extended H-bonding between GO and PANI.…”

“…Recent PANi- PANi/GO Nanocomposite 100 ppm [45] PANi Solid pellet 3000 ppm [42] PANI/Ti 3 (PO 4 ) 4 Nanocomposite Saturated vapor [46] PANi/PEO Electrospun nanofiber Saturated vapor [47] PANi/PS Extruded filament Saturated vapor [48] LOD limit of detection based composite alcohol sensors are compared in Table 2. The PANi/PEO/crGO-6 nanofiber sensor reported here responded to short-chain alcohols with a limit of detection (LOD) of 15 ppm, which is relatively low among PANibased chemiresistor alcohol sensors.…”

Electrospun nanofibers of a polyaniline (PANi)/ (?)-camphor-10-sulfonic acid (HCSA)/poly(ethylene oxide) (PEO) composite doped with different variants of graphene oxide (GO) were fabricated and evaluated as chemiresistor gas sensors operating at room temperature. A new strategy for enhancing PANi/PEO gas sensor performance is demonstrated using GO dopants reduced via thermal (trGO) or chemical (crGO) routes. By varying the chemical reduction duration (6 h, crGO-6 or 24 h, crGO-24), tunable enhancement of sensor response was achieved. Upon exposure to short-chain aliphatic alcohol vapors, the partially reduced crGO-6 dopant exhibited higher response than GO and crGO-24, suggesting that the dopant enhances sensor performance via increased electrical conductivity over neat GO, and enhanced hydrogen bonding capability over the further-reduced crGO-24 variant. Sensor arrays consisting of PANi/PEO doped with trGO, crGO-6 or crGO-24 moieties successfully identified methanol, ethanol, and 1-propanol vapors using principal component analysis (PCA).

“…Moreover, several studies discuss the production of multicomponent polymer nanocomposites from silica and other oxide particles coated with graphene oxide for the detection of dopamine [177]. Enhanced electrochemical electrodes for peroxide and glucose detection [103], methanol-sensitive nanocomposites with improved characteristics from polyaniline-graphene oxides [63], amplified colorimetric sensors for target DNA detection [166] have also been reported.…”

Graphene, a monolayer sp 2 hybridized carbon atom, received worldwide attention due to its extraordinary physical, chemical, thermal, and electrical properties. In recent years, the development of nanoscale dispersion techniques using graphene particles in a polymer matrix has been crowned a new and interesting horizon in material science. Graphene-based polymer nanocomposites reveal superior mechanical and thermal properties compared with the conventional graphite-based composites or neat polymers which are obtained through very low filler loadings in the polymer matrix. Graphene derivatives as unique nanofillers are used in the production of lightweight, low cost, and high-performance polymer nanocomposites with a wide range of applications, such as fuel cells, supercapacitors, solar cells, sensors, and lightweight gasoline tanks. This chapter reviews the preparation methods of graphene-based polymer nanocomposites, their characteristics, and their wide range of potential applications in technological fields.
