“…Ahirrao et al [3] used polyaniline coated with carbon cloth as the electrode material and reported a speci c capacitance of 691 Fg − 1 at 1 Ag − 1 , which is a higher capacitance value compared to pure polyaniline and still retained 94% of its initial capacitance after 2000 cycles. Ji et al [13] fabricated rGO-PANI composite with bio-inspired photo-/colloidal-lithography technique and reached a capacitance value of 614 Fg − 1 1 Ag − 1 with capacitive retention of 85% after 10000 cycles. Ajay et al [14] manufactured an electrode material by combining activated carbon obtained from orange peels with polyaniline and reached a capacitance of 427 Fg − 1 at 2 mVs − 1 with capacitive retention of 75% after 5000 cycles.…”

The design and exploration of carbon-based electrode materials have become highly signi cant for developing supercapacitor technology, which has attracted considerable attention in energy storage systems. Here, nitrogen-doped reduced graphene oxide (N-rGO) -Polyaniline (PANI) nanocomposites were synthesized by a facile two-step method in which in situ polymerization of aniline monomer was performed on hydrothermally synthesized N-rGO nanosheets in DBSA and H 2 SO 4 medium for co-doping of PANI chains. The effects of acid concentrations (DBSA:H 2 SO 4 0.5 − 0.25:1 n/n) and N-rGO:aniline ratio (N-rGO:aniline 1:4-10 m/m) used in the preparation of the electrode material on the capacitive properties were investigated. It is found that the codoped N-rGO-PANI nanocomposites exhibit a high speci c capacitance of 346.3 Fg − 1 at 1 Ag − 1 , remarkable rate capacity (99.9%, 1-10 Ag − 1 ) and excellent cycling stability at 5 Ag − 1 (81.3%, 5000 cycles) in a two-electrode system. As a result, constructing codoped PANI chains and N-doped rGO provided a viable and simple way to improve the capacitive performances of supercapacitors.

Direct laser interference patterning (DLIP) employing sub-picosecond IR irradiation allows for the ultrafast processing of polyaniline surfaces polymerized onto a poly(methyl methacrylate) substrate (PANI@PMMA) achieving excellent quality features. The patterning shows high levels of precision regarding control of width and height in micro/nanoarrays, giving customization to the surfaces. The electroactive property evaluation suggests the conductivity presents anisotropic characteristics following the patterning of the polymeric surfaces (R SL = 54 ± 5 kΩ sq −1 and R ST = 1.7 ± 3 MΩ sq −1 , longitudinal and transversal resistance modes respectively). The evidence is supported by electrostatic force microscopy measurements. These results indicate potential applicability in the biomedical field of nerve and myocardial tissue regeneration.

Polythiourethane (PTU) has attracted considerable attention in engineering building materials. Here, based on phosphazene nanoparticles (PZS‐1 and PZS‐2) prepared by water‐triggered and ultrasonic self‐assembly method, phosphazene/polythiourethane (PZS/PTU) composites with excellent mechanical strength, high flame retardancy and good transparency was obtained. Then, the comprehensive properties of both composites were evaluated, where PZS‐2 endowed PTU with better overall performance. Due to the good dispersibility of PZS and its strengthed interfacial interaction with PTU matrix, both PZS significantly enhanced mechanical and thermal property of PTU, where the tensile strength and glass transition temperature of PZS/PTU composites reached to 84.34 MPa and 59.94°C respectively. More importantly, compared to pure PTU, the values of peak heat release rate (HRR), total heat release rate (THR), smoke production rate (SPR), and total smoke production (TSP) of composites were decreased by 10.5%, 13.3%, 30.6% and 18.0%, respectively. The limiting oxygen index of composites was improved to 21.39% due to the catalytic carbonization of PZS, the expanded carbon layer and the incombustible gases released during combustion. Meanwhile, the PZS/PTU composite exhibited the high refractive index of 1.6580 and good transparency (not less than 85% at 500 nm). The PZS/PTU composite was promising candidates for optical flame retardant coatings and engineering building materials.
