Due to its low cost, natural abundance, non-toxicity, and high theoretical capacitance, cobalt oxide (CoO) stands as a promising candidate electrode material for supercapacitors. In this study, binder-less molybdenum doped CoO (Mo@CoO) integrated electrodes were one-step fabricated using simple electric discharge corrosion (EDC) method. This EDC method enables the direct synthesis of Mo@CoO active materials with oxygen vacancy on substrates, without any pre-made templates, conductive additives, or chemicals. Most importantly, precise control over processing parameter pulse width, which facilitates tailoring surface morphologies as-prepared materials. It was found that based symmetric supercapacitor prepared by width 24 μs (Mo@CoO-SCs24) achieved maximum areal capacitance 36.0 mF cm−2 (0.15 mA cm−2), is 1.83 1.97 times higher than Mo@CoO-SCs12 Mo@CoO-SCs36. Moreover, Mo@CoO-SCs24 devices could be worked at 10 V s−1, demonstrates their fast charge/discharge characteristic. These results demonstrated significant potential strategy efficiency fabricating various metal applications, like supercapacitors, batteries sensors.

Abstract Additive manufacturing enables the customization of parts according to user requirements. However, additive soft polymeric materials using melt‐based fused deposition modeling is challenging due issues such as low column strength, high melt viscosity, poor adhesion with print bed, and weak layer‐to‐layer adhesion. This work focused on development thermoplastic elastomeric nanocomposite based reduced graphene oxide (rGO) styrene‐isoprene‐styrene (SIS) triblock copolymer by direct ink writing (DIW) technique. The extrudability printability developed SIS‐rGO inks varying rGO loading are investigated from shear viscosity pressure drop analysis across different zones nozzle. Developed 3D printed nanocomposites showed good mechanical properties elongation at break (≥ 2000%) tensile strength (5–11 MPa). Microstructures samples distribution nanosheets in SIS matrix analyzed XRD TEM. Dielectric constant increased ≈6 times for 7 wt.% loaded compared pristine SIS. Additionally, electromagnetic interference shielding effectiveness (EMI SE) absorption also found increase 3D‐printed samples.

As one of the most common fossil derivatives, plastics are widely used for their exceptional chemical stability, low density, and ease processing. In recent years, there has been a significant increase in production waste plastics, coupled with recycling rate, resulting serious environmental pollution. To enhance use this research synthesized flame-retardant materials from hypercrosslinked polystyrene different molar fractions flame retardants. Waste foam was as raw material, while aniline, triphenylphosphine, melamine were employed additives. The additives successfully doped into porous skeleton structure through reaction or physical mixing to achieve situ retardancy, shaped by phenolic resin prepolymer. Then, samples characterized detail, results indicate that addition retardant enhances retardancy material. addition, material excellent thermal insulation performance, minimum conductivity 0.04176 W/(m·K).

Trans-1,4-polyisoprene (a thermoplastic crystalline polymer) and polystyrene (an amorphous or semicrystalline have been frequently used as important matrix materials for the formation of nanocomposites. has crystallinity toughness properties, whereas transparent brittle nature. These matrices revealed shape memory effects through inclusion carbon nanoparticles like graphene nanotube, well inorganic titania, silica, metal nanoparticles. The nanoparticle addition found to induce changes microstructural physical property alterations in matrices. This state-of-the art review article reports on stimuli responsiveness categories trans-1,4-polyisoprene based nanomaterials thermal, electric, radiation induced responses. High performance observed depending upon type, contents, interactions with polymer network. With graphene, black, high recovery responses 95%–99%. nanocomposites copolymers blends also depicted up 100%. its different types exhibited effective thermo responsive electro active behavior. Consequently, attributed homogeneous dispersion network an chain switching.
