“…Conducting polymers (CPs), such as polypyrrole (PPy), polyaniline (PANI) and polythiophene (PTh) and their derivatives [11], have been considered as promising candidates because of their high theoretical specific capacitances, low cost, facile synthesis, fast charge/discharge electron-transfer kinetics, and high conductivity in the doped state [12]. The reasons accounting for this phenomenon are probably the susceptibility of the furan on the side reactions during the polymerization and low stability of the resulting polymers [23][24][25][26].

A series of furan-EDOT copolymer films, namely, P(Fu-EDOT), P(Fu-EDOT-Fu) and P(EDOT-Fu-EDOT), were electrochemically synthesized from their corresponding monomers and evaluated as active electrode materials for supercapacitor applications by galvanostatic charge-discharge method. The specific capacitance of these copolymers was calculated to be 65, 46 and 75 F g -1 at a current density of 1 A g -1 , respectively. Besides, their energy density were also investigated. Among them, P(EDOT-Fu-EDOT) exhibited higher specific capacitance and energy density (15 Wh kg −1 at a power density of 0.6 KW kg −1 ) than P(EDOT-Fu) and P(Fu-EDOT-Fu), and also showed a large power range while maintaining a relatively high energy density. These favorable performances make P(EDOT-Fu-EDOT) a promising candidate as electrode material for supercapacitors compared with P(Fu-EDOT-Fu) and P(EDOT-Fu).

“…But they lack processability to form fibres or filaments due to their inherent structural intractability and stiffness that comes from conjugation along molecular chain [2,3]. Among these conductive polymers, polypyrrole (PPy) has low cost, good environmental stability, and satisfactory electrical conductivity in doped condition [4][5][6][7]. Textile materials are insulator but strong, light-weight, and flexible.…”

Electrically conductive woven, knitted, and nonwoven composite fabrics are prepared by in situ chemical polymerization of pyrrole using suitable oxidant and dopant. These composite fabrics show surface resistivity in the range ∼1 to 2 kΩ. These composite fabric can alter their resistivity with various stimuli such as mechanical strain, pH, and humidity. So, in the present study, their response to pH, humidity, and mechanical strain is investigated. For all fabrics, similar behaviour has been observed regarding pH versus resistivity. The resistance of the composite fabric increases with the increase of alkalinity of pH. However, as bending strain increases, resistance steeply decreases for cotton fabrics, steeply increases for polyester fabrics, and initially decreases and then increases for wool fabrics. Regarding humidity sensitivity, sigmoid curves have been obtained for all kinds of fabrics.

“…Corma and co-workers further exemplified the "oligomerization" of MF with a number of biomass-derived aldehydes and ketones; notably, aldehydes (e.g., pentanal) exhibited higher reaction rates than ketones (e.g., 2-pentanone) [2]. Besides the acid-catalyzed oligomerization, the polymerization of furans with oxidizing agents has been investigated [4][5][6]. During this reaction, the furan rings do not open and the furan chain (polyfuran) is dehydrogenated.…”

a b s t r a c tThe conversion of biomass to fuels and chemicals is considered to be a promising alternative to petroleumbased conventional routes. The oligomerization of biomass-derived furans can yield an important precursor toward diesel fuel; yet, the underlying mechanism is not well understood. This study investigates the furan oligomerization mechanism and kinetics via density functional theory and microkinetic modeling. The oligomerization proceeds in the presence of water and a Brønsted acid and requires an aldehyde and two furan molecules, each with at least one unprotected ␣-C. If only furans are present in the acidic, aqueous environment, the initial hydrolysis to produce the aldehyde limits the oligomerization rate. Two strategies to accelerate the oligomerization are proposed: furnishing the furans with electron-donating substituents or supplying a non-self-condensing aldehyde in the reaction mixture.
