{Co4O4} Cubanes in a conducting polymer matrix as bio-inspired molecular oxygen evolution catalysts

Exploration of efficient molecular water oxidation catalysts for long-term application remains a key challenge for the conversion of renewable energy sources into fuels. Cuboidal {Co4O4} complexes keep attracting interest as molecular water oxidation catalysts as they combine features of both heterogeneous and homogeneous catalysis with bio-inspired motifs. However, the application of many cluster-based catalysts for the oxygen evolution reaction still requires new stabilization strategies. Drawing inspiration from the stabilizing effects of natural polymers, we introduce a conductive polymer-hybrid approach to covalently immobilize {Co4O4} cubane oxo clusters as oxygen evolution catalysts. Polypyrrole is applied as an efficient p-type conducting polymer that promotes hole transfer during the oxygen evolution reaction, resulting in higher turnover frequency compared to the pristine {Co4O4} oxo cluster and heterogeneous Co-oxide benchmarks. The asymmetric coordination of {Co4O4} not only mitigates catalyst decomposition pathways, but also increases the catalytic efficiency by exposing a directed cofacial dihydroxide motif during catalysis.

Factor analysis on property enhancement of electrically/thermally conductive composites by continuous forced assembly

AbstractCurrently, with the development of many important fields such as aerospace and automotive industries, polymer composites have become an indispensable part of these fields. As for preparation methods, common methods like hot pressing make composites difficult to achieve continuous production. This paper proposed the continuous forced assembly (CFA) and designed continuous production facility, which can achieve the continuous preparation of low filler content (30 wt%) composites with high electrical/thermal conductivity. Besides, we structurally designed roll pressing device and explored its effect on the machining process. Here, short cut carbon fiber (SCF) and solid silica gel (MVQ) are used as electrically/thermally conductive filler and polymer matrix respectively, and continuous preparation of functional composites is completed by CFA method. Compared to the thermal conductivity (1.186 W/(m·K)) of SCF/MVQ composites prepared with lower viscosity matrix (MVQ‐A), the thermal conductivity of composites prepared with high viscosity matrix (MVQ‐D) reached 2.230 W/(m·K). Meanwhile, the process is optimized to explore the effects of the “accordion folding” and “pre‐stretch” methods on the thermal conductivity of composites, the thermal conductivity is converted from in‐plane to vertical direction. In addition, under the same filler content, 2 wt% rGO is beneficial in enhancing the electrical/thermal conductivity of prepared composites. The electrical conductivity and thermal conductivity of SCF28/rGO2/MVQ composite reach 663 S/m and 2.82 W/(m·K), which is higher than that of the properties of SCF/MVQ composite with the same filler content. To sum up, CFA facilitates continuous production of composites, which can be used in thermal management materials (TMMs).Highlights Compared with the “pre‐stretch” method, the thermal conductivity of SCF/MVQ composites prepared by “accordion folding” has a significant improvement. The SCF/rGO/MVQ composites prepared by CFA method show superior thermal conductivity and electrical conductivity. Composites prepared by CFA method can realize the continuous preparation of functional materials.

Integrated design and manufacturing of a soft robotic glove with piezoresistive sensors

Soft robotic gloves that assist people in acquiring hand movement and gesture for various applications have been developed by various design and manufacturing methods over the decades. Major concerns in the recent development of gloves involve finger-related sensibility and effectiveness of movement acquisition as applied by various means for different applications. Also, remarkable progress in developing advanced materials and structures has resulted in promising design and fabrication using different methods. This paper reports a hybrid 3D printing approach that can be realized by an integrated design and manufacturing (IDM) scheme with direct ink writing (DIW) and fused deposition modeling (FDM) sequentially. Preparing a conductive polymer matrix composite (PMC) incorporating graphene and graphite with silicone rubber, the DIW sensor of the PMC embedded onto an FDM robotic glove of thermoplastic polyurethane was illustrated to demonstrate the piezoresistive effect on deformation of the structure in which an essential change in the electrical resistance was detected during bending and recovering. It showed remarkable sensibility over the deformation of the resistors and the fingers’ bending with various degrees. In the future, innovative composites and structures of robotic gloves based on DIW and FDM of the present IDM scheme could be further explored in applications such as human-machine interfaces.

Rare Earth metal oxide nanoparticle-infused polymer nanocomposites for enhanced supercapacitor electrodes

The contemporary energy shortage has spurred scientists to explore other options. In this regard, there's significant interest in utilizing electrochemical energy sources for converting and storing energy. Here, a fresh endeavor involves utilizing a set of semiconducting rare earth Gd2O3/conducting polymers (CP) (CP= polypyrrole, polyindole) for energy storage purposes. The synthesis method involves the straightforward oxidative polymerization of either indole or pyrrole to produce Gd2O3/PIn or Gd2O3/PPy, respectively. The integrity of the garnets synthesized was verified through XRD, Raman, XPS, FESEM, and TEM analysis, ensuring their phase purity and morphology. The scanning electron microscopy (SEM) analysis reveals the particle morphology, with sizes ranging from 100 to 800 nanometers. FTIR and Raman spectroscopy further validate the integration of Gd2O3 into the conducting polymer matrix. XRD shows broad peaks for amorphous structures in Gd2O3/PPy and Gd2O3/PIn nanocomposites. To evaluate its performance in supercapacitors, cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and impedance spectroscopy (EIS) were employed using a three-electrode configuration. The rectangular CV curves indicate the pseudo-capacitance mechanism of the Gd2O3/CP nanocomposite-coated carbon fiber electrode in an H2SO4 electrolyte. Specific capacitance (SC) values for Gd2O3/PPy and Gd2O3/PIn binary nanocomposite electrodes are determined as 341.61 F/g and 305.56 F/g, respectively, from GCD curves. In hybrid energy systems, especially electric automobiles, the Gd2O3/PPy and Gd2O3/PIn nanocomposite-coated carbon fiber electrode has a potential of up to 1.8 V and short charging and discharging durations, implying fast-charging and extended lifespan. The easy oxidative polymerization process utilized to produce gadolinium oxide/conducting polymer nanocomposites for supercapacitors is the main breakthrough of this research.

Simultaneous Electrochemical Detection of Multiple Bacterial Species Using Metal-Organic Nanohybrids.

Organic metallic nanohybrids (NHs), in which many small metal nanoparticles are encapsulated within a conductive polymer matrix, are useful as sensitive electrochemical labels because the constituents produce characteristic oxidation current responses. Gold NHs, consisting of gold nanoparticles and poly(m-toluidine), and copper NHs, consisting of copper nanoparticles and polyaniline, did not interfere with each other in terms of the electrochemical signals obtained on the same electrode. Antibodies were introduced into these NHs to function as electrochemical labels for targeting specific bacteria. Electrochemical measurements using screen-printed electrodes dry-fixed with NH-labeled bacterial cells enabled the estimation of bacterial species and number within minutes, based on the distinct current response of the labels. Our proposed method achieved simultaneous detection of enterohemorrhagic Escherichia coli and Staphylococcus aureus in a real sample. These NHs will be powerful tools as electrochemical labels and are expected to be useful for rapid testing in food and drug-related manufacturing sites.

A Fully Amorphous, Dynamic Cross-Linked Polymer Electrolyte for Lithium-Sulfur Batteries Operating at Subzero-Temperatures.

Solid-state lithium-sulfur batteries have shown prospects as safe, high-energy electrochemical storage technology for powering regional electrified transportation. Owing to limited ion mobility in crystalline polymer electrolytes, the battery is incapable of operating at subzero temperature. Addition of liquid plasticizer into the polymer electrolyte improves the Li-ion conductivity yet sacrifices the mechanical strength and interfacial stability with both electrodes. In this work, we showed that by introducing a spherical hyperbranched solid polymer plasticizer into a Li+ -conductive linear polymer matrix, an integrated dynamic cross-linked polymer network was built to maintain fully amorphous in a wide temperature range down to subzero. A quasi-solid polymer electrolyte with a solid mass content >90 % was prepared from the cross-linked polymer network, and demonstrated fast Li+ conduction at a low temperature, high mechanical strength, and stable interfacial chemistry. As a result, solid-state lithium-sulfur batteries employing the new electrolyte delivered high reversible capacity and long cycle life at 25 °C, 0 °C and -10 °C to serve energy storage at complex environmental conditions.

Preparation of Short Carbon Fiber/Polydimethylsiloxane Conductive Composites Based on Continuous Spatial‐Confining Network Assembly Technique

With the development of electronic devices, conductive composites are receiving more and more attention, the demand for electrically conductive composites (ECC) is also increasing. However, the existing preparation process does not allow for the continuous preparation of electrically conductive composites. Therefore, we report a continuous spatial‐confining network assembly (CSNA) technique method to achieve an efficient and controllable preparation of electrically conductive composites. Short carbon fiber (SCF) and polydimethylsiloxane (PDMS) are used as conductive fillers and polymer matrix to prepare conductive composites, and the filler content of the prepared composites is 6 wt%. The electrical conductivity of the PDMS/SCF conductive composite is 73.72 S m−1, when flexible roll with a Shore hardness of 12.5 A and a roll pressure of 126 N is used. The effect of increasing pressure, the higher the number of rolls and the roll speed on the electrical properties of the composite, is also investigated. To sum up, the PDMS/SCF composite prepared by this preparation method is expected to achieve continuous production and application in medical, biological, thermal management, etc.

Research Progress on Intrinsically Conductive Polymers and Conductive Polymer-Based Composites for Electromagnetic Shielding.

Electromagnetic shielding materials are special materials that can effectively absorb and shield electromagnetic waves and protect electronic devices and electronic circuits from interference and damage by electromagnetic radiation. This paper presents the research progress of intrinsically conductive polymer materials and conductive polymer-based composites for electromagnetic shielding as well as an introduction to lightweight polymer composites with multicomponent systems. These materials have excellent electromagnetic interference shielding properties and have the advantages of electromagnetic wave absorption and higher electromagnetic shielding effectiveness compared with conventional electromagnetic shielding materials, but these materials still have their own shortcomings. Finally, the paper also discusses the future opportunities and challenges of intrinsically conductive polymers and composites containing a conductive polymer matrix for electromagnetic shielding applications.

3D printing of conductive polymer aerogel thermoelectric generator with tertiary doping

The rapid advancement of conductive polymer aerogel for thermoelectric application has predominantly depended on the use of performance-enhancing additives for improvement in electrical performance. Meanwhile, the intrinsic capability of the polymer matrix is often overlooked, and control over aerogel geometry remains limited. This arises from the challenges in fabricating conductive polymer aerogel film and the absence of an effective doping technique that does not compromise the aerogel’s fragile microstructure due to induced capillary stress. Herein, 3D printing is combined with a tertiary doping process to simultaneously enable synthesize of conductive polymer aerogel with controlled geometry, high electrical conductivity of over 10 Scm−1, low thermal conductivity of < 100 mWm−1K−1, while increasing the thermoelectric output by four times compared to pristine aerogel. The result of this work opens new opportunities to enhance the performance of conductive polymer without relying on additives by unleashing the full potential for conductive polymer matrix.

Developing Single‐Ion Conductive Polymer Electrolytes for High‐Energy‐Density Solid State Batteries

AbstractSingle‐ion conductive polymer electrolytes (SICPEs) with a cationic transference number (tLi+) close to unity exhibit specific advantages in solid‐state batteries (SSBs), including mitigating the ion concentration gradient and derived problems, suppressing the growth of lithium dendrites, and improving the utilization of cathode materials and the rate performance of SSBs. However, the application of SICPEs remains major challenges, i.e., the ionic conductivity is inferior at room temperature. Therefore, the recent accomplishments in improving the ambient ionic conductivity to be compatible SICPEs with a high transference number are discussed in this review. In particular, some strategies of delocalizing charges in polyanions, designing a highly conductive polymer matrix, and utilizing synergistic effects in SICPEs are focused to shed light on the further development of solid polymer electrolytes for SSBs. Finally, multifunctional species of SICPEs are discussed in view of the mechanical contact and/or charge transfer problems at the solid–solid interface in SSBs.

Polymeric interfacial engineering approach to perovskite-functionalized organic transistor-type gas sensors

Organic semiconductors (OSCs) are promising sensing materials for printed organic gas sensors. Although OSCs show promise since they are mechanically flexible, cost-effective, and lightweight, they still face challenges related to low sensitivity and poor stability under ambient conditions; their development therefore lags that of inorganic-based gas sensors. Functional nanomaterials can be incorporated into organic semiconductors to complement the gas sensitivity and stability. Herein, we describe the fabrication of novel organic–inorganic hybrid gas sensors via the blending of perovskite nanocrystals and conductive polymer. We introduced a perovskite-structured material, CsPbBr3, into a conductive polymer matrix, which substantially improved its gas-sensing performance while maintaining its high responsivity and response rates. To further improve the adsorption of target gas molecules, we modified the surface of the perovskite using a zwitterionic polymer subjected to a hydration treatment. The results demonstrate that the amide group of the encapsulation polymer exhibits high affinity toward NO2 gas molecules and that this affinity becomes more pronounced upon hydration of the polymer. We also demonstrate the perovskite materials in the semiconducting polymer layer can protect the polymer thin film against oxidation during prolonged storage under ambient conditions because of the perovskite crystals’ ability to adsorb oxidizing molecules.

Electromagnetic attenuation displayed by La-Co substituted Ba-Sr hexaferrite nanoparticles and multiwall carbon nanotubes in polyaniline and polythiophene matrix

Our presented research aims to provide a systematic study of electrical, magnetic and microwave absorption properties of La-Co substituted Ba-Sr hexaferrite nanoparticles and MWCNTs, encapsulated in conductive polymer matrix. La-Co substituted Ba-Sr hexaferrite nanoparticles were produced using Sol-Gel auto combustion, whereas carrier fluid ultrasonication dispersion and in-situ polymerization were used to synthesize their composites with multiwall carbon nanotubes (MWCNTs) and conductive polymers. Structural investigations were accomplished using X-rays diffraction, secondary electron microscopy, Infrared and Raman Spectroscopy. The dielectric measurements revealed increased dielectric losses (4.86 at 1 GHz for pure nanoparticles, which increases up to 11.59 and 13.36 for ternary composites within PANI and PTh matrix), indicating good energy dissipation behavior. The decrease in magnetism was observed due to the weakening of exchange coupling or domain wall pinning at the interface of Ferrite-MWCNTs and Ferrite-Polymer, resulting in lowered saturation magnetization, remanence and coercivity values. The microwave absorption of our samples was evaluated as a function of frequency and thickness, revealing its dependence on the quarter wavelength phenomenon with maximum reflection loss of − 40.4 dB observed for ternary composite with Polythiophene matrix at 7.54 GHz resonance frequency. The dependence of reflection loss peaks on matching thickness was analyzed using calculated thickness profiles, revealing their close agreement with simulated thickness. The study highlighted the potential of synthesized samples for electromagnetic signature reduction, in both commercial and military applications. The resonance bands were found to coincide with the operating frequency of military radars for shipborne and airborne surveillance and navigation in the X band (8–12 GHz).

Encapsulation of Ba–Sr hexaferrite nanoparticlesand MWCNTs in conductive polymer matrix for improved dielectric spectroscopy, electromagnetic shielding and microwave absorption applications

Ba–Sr hexaferrite nanoparticles were produced using Sol-Gel auto combustion, whereas carrier fluid ultrasonication dispersion and in-situ polymerization were used to synthesize their composites with MWCNTs and conductive polymers. Structural investigations were accomplished using X-rays diffraction, secondary electron microscopy, Infrared and Raman Spectroscopy. The low frequency dielectric measurements revealed increased dielectric losses (304 at 100 Hz for pure nanoparticles, which increases up to 2721 and 7861 for ternary composites within polyaniline and Polythiophene matrix), indicating good energy dissipation behavior. The diminishing magnetism resulted from the weakening of exchange coupling or domain wall pinning at the interface of Ferrite-MWCNTs and Ferrite-Polymer, causing the shifting of magnetic resonance peak towards lower frequency in the shielding effectiveness (Absorption) plots. Increasing DC conductivity adds to the nominal increase of Shielding effectiveness (Reflection) values owing to the rise in charge carrier conduction. The maximum total shielding effectiveness, perceived for the composition of Ba0.5Sr0.5Fe12O19/MWCNTs/Polythiophene, was −34 dB and −33 dB at 8.1 GHz and 16.2 GHz, respectively. The microwave absorption of our samples was evaluated as a function of frequency and thickness, revealing its dependence on the quarter wavelength phenomenon with maximum reflection loss of −39 dB observed for ternary composite with Polythiophene matrix at 7.4 GHz resonance frequency. The resonance bands coincide with the operating frequency of military radars for shipborne and airborne surveillance and navigation in the X band.

Influence of filler type and content on thermal conductivity and mechanical properties of thermoplastic compounds

AbstractCombining thermal conductivity with electrical isolation is a very interesting topic for electronic applications in order to transfer the generated heat. Typical approaches combine thermally conductive fillers with a thermoplastic matrix. The aim of this work was to investigate the influence of different fillers and matrices on the thermal conductivity of the polymer matrix composites. In this study, various inorganic fillers, including aluminum oxide (Al2O3), zinc oxide (ZnO), and boron nitride (BN) with different shapes and sizes, were used in matrix polymers, such as polyamide 6 (PA6), polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane (TPU), and polysulfone (PSU), to produce thermally conductive polymer matrix composites by compounding and injection molding. Using simple mathematical models (e.g., Agari model, Lewis–Nielson model), a first attempt was made to predict thermal conductivity from constituent properties. The materials were characterized by tensile testing, density measurement, and thermal conductivity measurement. Contact angle measurements and the calculated surface energy can be used to evaluate the wetting behavior, which correlates directly with the elastic modulus. Based on the aforementioned evaluations, we found that besides the volume fraction, the particle shape in combination with the intrinsic thermal conductivity of the filler has the greatest influence on the thermal conductivity of the composite.

Improved Elasticity and Conductivity in a Ni@Ag/Silicone Rubber Composite due to Lowered Percolation Threshold via Magnetic-Field-Induced Alignment

Elastic and conductive electrodes are required for deformable electronic devices. The electrical conductivity and elasticity of a composite material are governed by the proportions of conductive filler and polymer matrix, respectively. Achieving these two features simultaneously is challenging because of the trade-offs between them. The conductive filler content must be higher than the percolation threshold to achieve conductivity. However, if the percolation threshold could be lowered, conductivity could be achieved even with a low content of the conductive filler, and elasticity could be achieved simultaneously by increasing the content of the polymer matrix. Herein, a Ni@Ag/silicone rubber composite with a decreased percolation threshold via magnetic field alignment is reported. The magnetic/conductive particles were arranged and compressed in a parallel straight-line pattern using an external magnetic field. The resulting pseudo-one-dimensional (1D) morphology lowered the percolation threshold of the composite by more than 20% and maintained its electrical properties at 20% cyclic stretching. However, composites that were oriented one way were only able to withstand stretching in a perpendicular direction. By creating a cross-directional orientation procedure, we were able to resolve this problem. In addition, factors affecting the conductivity and elasticity, such as the strength and direction of the magnetic force and the content of the multi-walled carbon nanotubes (MWCNTs), were studied. The MWCNTs served as the nonmagnetic conductive secondary filler, helped control viscosity, and improved the elasticity. Through an light-emitting diode (LED) demonstration, it was proved that the magnetic-field-induced alignment process can be applied to a circular electrode circuit for deformable electronics.

Wearable Conductive Polymer Matrix Composites for Breath Monitoring with Ammonia Detection

Conductive polymers, such as polyaniline (PANI), Polythiophene (PTh), polypyrrole (PPy), etc., are widely used for gas sensors due to their excellent electrical conductivity and low cost to manufacture [1]. In particular, PANI has attracted more attention due to its ease of synthesis, high environmental stability, and high reactivity with ammonia gas. In addition, the selection of acid-base dopant during the preparation process of polyaniline can adjust carrier concentrations for the change in electrical conduction or resistance to improve sensing properties. There have been many reports on the fabrication of flexible gas sensors using PANI [2-4]. Bandgar et al. [5] synthesized a low-temperature flexible polyaniline gas sensor by in-situ chemical oxidation polymerization of aniline on a polyethylene terephthalate (PET) substrate, showing 99% reproducibility, rapid response and recovery. Still, the response value was only 26% in 100 ppm ammonia atmosphere. Qi et al. [6] prepared a gas sensor by in-situ polymerization of aniline on non-woven fabric. The high air permeability of the fabric effectively improved the performance of the polyaniline-based gas sensor. Due to the outbreak of the COVID-19 pandemic, the use of face masks in public has become essential to reduce the spread of the virus. Some reports claim that the increased carbon dioxide in the mask over time may cause medical issues related to the respiratory system. Therefore, monitoring breathing air quality can help detect the wearer's vital conditions.In this study, we used a disposable mask as a flexible substrate to prepare polypropylene/carbon nanotube/polyaniline composite film through a layer-by-layer method. The polypropylene/carbon nanotube composite films were prepared by applying the carbon nanotube aqueous solution with surfactants evenly on the surface of a mask filter layer by a drop-coating method. Then, the in-situ polyaniline polymerization was performed on the surface of the polypropylene/carbon nanotube composite film through ammonium sulfate. The polypropylene/carbon nanotube /polyaniline composite film exhibits high sensitivity, fast sensing response/recovery time, room temperature operation, reliable flexibility, and cycle stability. The synthesized and wearable masks have demonstrated real-time detection respiratory rate and other breathing conditions such as CO2 and humidity. The ammonia gas sensing can also be used as a potential biomarker for health screening. The design and integration of multiple gas sensing materials in masks will help wearers better understand their own body conditions.

Ceramic/Polymer Hybrid Electrolyte with Enhanced Interfacial Contact for All-Solid-State Lithium Batteries

All solid-state lithium batteries (ASSLBs) with a high energy density are challenging, yet desired by the rising energy demands. Its intrinsic safety of solid-state electrolytes (SSEs) compared to flammable liquid electrolytes makes ASSLBs a modern-day necessity. NASICON-type Li1.5Al0.5Ge1.5P3O12 (LAGP) has high ionic conductivity, high stability against air and water, and a wide electrochemical window. However, the application of LAGP is significantly hindered by its slow interfacial kinetics and brittle nature. In addition, the ionic conductivity of LAGP is relatively low at room temperature compared to that obtained at elevated temperatures. In our study, LAGP was incorporated into a polymer matrix to accelerate charge transport at the electrode-electrolyte interface to form LAGP-poly-DOL (LAGP-pDOL) hybrid electrolyte. The in-situ cationic ring-opening polymerization of DOL decreases the interfacial contact impedance and improves the mechanical properties of the SSE. LAGP-pDOL electrolyte exhibits prolonged cycle stability in symmetric cells (> 200 h) and in Li|LiFePO4 full cells (99% retention after 50 cycles) at room temperature. This study demonstrates the effective utilization of conductive polymer matrix into LAGP to enhance mechanical strength, interfacial contact, and room temperature electrochemical performance.

Ultra-high-strength self-healing supramolecular polyurethane based on successive loose hydrogen-bonded hard segment structures

Solving the weak toughness and strength of self-healing materials seems to be a mountain that is difficult to get over. Although some studies have reported high-strength self-healing materials, human intervention and long heal time are needed as compensation to self-heal. The balance between mechanical properties and self-healing efficiency is still challenging. Here, a high-strength self-healing supramolecular polyurethane is constructed based on a continuous loose hard segment structure. The polyurethane exhibits a maximum tensile strength greater than 45 MPa, maximum elongation at break of 850 %, and a tear strength of up to 118.776 KJ/m3, a self-healing efficiency of 95 %, which can effectively prolong the service life of the material. Strong soft segments and high-density loose hydrogen bond arrays are the source of strong mechanical strength. The asymmetric alicyclic loose hard segment structure ensures sufficient mobility of the molecular segments to complete hydrogen bond recombination in a short time. At the same time, its research as a conductive polymer matrix has been verified to restore 90 % of the conductivity, showing great application potential in the field of self-healing conductive composite material.
