Three kinds of high-molecular-weight compatibilizers [copoly(1,4-phenylene sulfide)-poly(2,5-phenylene sulfide amine)] (PPS-NH 2 ) containing different proportions of amino units in the side chain) were synthesized by the reaction of dihalogenated monomer and sodium sulfide via nucleophilic substitution polymerization under high pressure. The intrinsic viscosity of the obtained copolymers was 0.354–0.489 dL/g and they were found to have good thermal performance with melting point ( T m ) of 271.3–281.0 °C and initial degradation temperature ( T d ) of 490.0–495.7 °C. There was an excellent physical compatibility between PPS-NH 2 and the pure industrial PPS. The results of dynamic mechanical analysis and macro- and micromechanical test showed that the selective compatibilizer PPS-NH 2 (1.0) (1.0% mol aminated ratio) can improve the mechanical and interfacial properties of polyphenylene sulfide/glass fiber (PPS/GF) composite. The macro-optimal tensile strength, Young's modulus, bending strength, and notched impact strength of 5%PPS-NH 2 (1.0)/PPS/GF composite raised up to 141 MPa, 1.98 GPa, 203 MPa, and 6.15 kJ/m 2 , which increased 12.8%, 9.4%, 4.1%, and 13.8%, respectively, comparing with the pure PPS/GF composite (125 MPa, 1.81 GPa, 195 MPa, and 5.40 kJ/m 2 , respectively). © 2017 Wiley Periodicals, Inc.

The formation of conductive anodic filament (CAF) inside printed circuit boards (PCBs) is one of the major failure modes related to the long-term reliability of electronic devices. In this paper, the relationship between susceptibility to CAF formation and glass fiber/resin interfacial bonding strength of a thermosetting polyphenylene oxide (PPO)/glass fiber composite system was investigated. Laminates with different interfacial bonding strengths were prepared by coating glass fibers with different silane coupling agents. Interlaminar shear strength (ILSS) of the PPO composites with silane-treated glass fibers has been improved by around 30 %, compared to the PPO/glass fiber composite without silane treatment . An accelerated response to CAF susceptibility was realized by substantially reducing the hole wall to hole wall distance of PCB to 5mil and 7 mil. By correlating the test results of interlaminar shear strength , haloing effect and susceptibility to CAF formation, it is confirmed that the CAF resistance of PCBs is positively correlated with the glass fiber/resin interfacial bonding strength.

The resulting composites exhibit remarkable self-healing properties and enhanced recyclability by incorporating dynamic, reversible polyimine bonds into the epoxy matrix. Subsequently, glass fibers (GF) were modified using 3-aminopropyltrimethoxysilane (APTMS) to improve interfacial adhesion with the epoxy/polyimine matrix. Scanning electron microscopy (SEM) analysis revealed that the modified GFs significantly contribute to mechanical reinforcement through crack bridging, stress transfer, and energy dissipation. Experimental results showed that the addition of APTMS-modified glass fibers (AGF) improved the tensile strength and modulus of the AGF/EP/PI composites. When the content of AGF is 10%, the tensile strength and modulus of the composite reach 63.3 and 301 MPa, respectively, an increase of 27% and 25% compared to the EP/PI matrix. The introduction of AGF also significantly enhances the impact resistance, with the impact strength of the composite containing 5% AGF increased by 43% compared to the matrix. In terms of cycling performance, the EP/PI matrix material demonstrates excellent recyclability. After multiple cycling tests, the overall performance of the AGF/EP/PI composite remains high. It results in excellent cycling performance, providing new design ideas for the development of high-performance, recyclable pressure shell composites.

Hardness or brittleness limits the broad applications of currently available high-performance piezoelectric sensors in emerging fields like human-machine interface and wearable electronics , while existing technologies for fabricating flexible piezoelectric sensors often require high-temperature sintering or complex processes. Here, we reported flexible piezoelectric sensors based on 10 nm BaTiO 3 nanocubes self-assembled on glass fiber fabric (GFF). The simple self-assembly process avoids high temperature sintering process which can well maintain the mechanical performance of GFF. Owing to the superior piezoelectric performance of BaTiO 3 nanocubes and robust mechanical properties of GFF, the integrally fabricated flexible piezoelectric sensors achieved high sensitivity (101.09 nA kPa −1 and 3.31 V kPa −1 in the low pressure range of 0–10 N) and short response time (19 ms). The sensors can intelligently identify handwriting or recognize the user of keyboard, and the initially collected electrical signals are essentially the same as those after 3000 bending cycles. This work provides a novel self-assembly process to develop fabric-based flexible electronics, which promotes the development of self-powered piezoelectric sensors and creates advancements in human-machine interfaces.

Inflammation quantification through the detection of cytokines and inflammatory factors in a point-of-care scenario is crucial for managing and preventing diseases. Achieving early-stage inflammation quantification in osteoarthritis (OA), before the radiographic findings become apparent, may provide an opportunity for accurate diagnosis and effective therapy, potentially preventing joint degeneration. Here, we developed a glass-fiber-based universal system with CRISPR-Cas12a-based immunosensors (GUSCI) for simultaneous detection of multiple inflammation biomarkers using a portable fluorescence detection device. GUSCI enables the detection of five inflammation biomarkers (interleukin-4 [IL-4], IL-6, tumor necrosis factor alpha [TNF-α], interferon γ [IFN-γ], and matrix metalloproteinase 3 [MMP-3]) with picomolar sensitivity in a 10-μL sample while having less than 75 min of assay time and a smartphone signal readout. A cohort study of 35 synovial samples from OA patients revealed differences in inflammation levels. This “sample in, answer out” platform not only aids in understanding OA progression but also offers a versatile strategy for point-of-care diagnosis of a wide range of diseases in resource-limited settings.

Aqueous zinc-ion batteries (AZIBs) have received increasing attention as a promising energy storage device. However, it was rarely reported that the separators as a synergistic medium stabilize the cathode and anode materials. Herein, a polyaniline functionalized glass fiber separator (PANI-GF) was synthesized in situ . The porous structure of PANI effectively regulated the flux of zinc ions inside the separator and its deposition behavior through ion confinement. The abundant N -containing functional groups can adsorb water molecules and effectively reduce harmful side reactions. Moreover, the PANI-GF separator adjusted pH to inhibit dissolution of the cathode by protonation. Importantly, based on the synergistic separator, the Zn-MnO 2 full cell exhibited more than twice discharge capacity compared to the conventional cell after 1000 cycles at 2 A g −1 . This study provided in-depth insight into the design of convenient, reliable, cost-effective, and synergistic separators for AZIBs.

In order to fabricate epoxy-based glass fiber composites with superior mechanical and thermal properties, starch was chemically modified by E-51 epoxy resin, as a sizing for glass fibers. The hydrophilicity of starch was enhanced after modification as the surface tension decreased from 64.98 to 47.99 mN m−1, and the contact angle between the starch suspension and slide glass decreased from 50.26° to 33.53°. Besides, the interfacial adhesion between glass fiber and epoxy resin was obviously improved with the help of the modified starch, which can be clearly observed from SEM images. Consequently, significant increases of tensile strength from about 35 MPa to over 57 MPa, bending strength from about 65 MPa to over 87 MPa, and impact strength from about 8 KJ m−2 to over 14 KJ m−2 were obtained. Moreover, with the improvement of interfacial adhesion between the modified-starch sized glass fiber and epoxy resin, the thermo-stability of the composite was also improved as demonstrated by DSC. This study suggested a simple but effective chemical modification technique using a modifier to enhance interfacial adhesion in fabricating epoxy-based glass fiber composites with superior properties.

A glass fiber/polyimide (PI)/SiO 2 composite aerogel (FPS aerogel) was prepared by dispersing glass fibers in PI/SiO 2 hybrid sol derived from 4,4′-oxydianiline (ODA), pyromellitic dianhydride (PMDA) and tetraethoxysilane (TEOS) with supercritical CO 2 fluid drying technology. The SiO 2 primary particles were combined with PI chains which improved the strength of the composite aerogel, and the glass fibers inhibited the shrinkage deformation during the drying process by acting as the supporting skeletons. Effects of PI contents on the density, shrinkage, thermal conductivity and mechanical properties of the FPS aerogels were investigated. The as-prepared FPS aerogels had low densities (0.116–0.145 g/cm 3 ), high specific surface area (844–963 m 2 /g), low thermal conductivity (0.0268–0.0280 W m −1 K −1 at room temperature) and relatively high compression strength (0.12–0.29 MPa) with integrated nanostructures, fewer powders and stronger fiber/aerogel matrix interfaces. The density, the shrinkage, the thermal conductivity and the compression strength of the FPS aerogels increased with the increasing PI content. This research provided a new method employing PIs and glass fibers as strengthening phases to improve the mechanical properties of SiO 2 -based aerogels.

Nitrile rubber composite with aligned glass fibers (GFs/NBR composites) were prepared by direct-ink-writing (DIW) technology for application in flexible thermal management of electronic equipment.The alignment and orientation (0°, 45° and 90°) of glass fibers was precisely tuned by shear force field and 3D printing direction. Furthermore, the effect of print direction on the mechanical properties , thermal conductivity and heat dissipation performance were investigated. The tensile strength (1.78 MPa) and thermal conductivity (1.2 W m −1 K −1 ) of GFs/NBR composites with a 90° orientation was improved to be 149.6% and 300% compared to the composites with disordered orientation, respectively. The temperature of LED device and computer’ CPU covered with GFs/NBR composites with a 90° orientation was reduced by ca. 8.1 °C and 4.1 °C, respectively. The study confirmed the formation of GFs/NBR composites with controlled alignment and orientation for various applications.

As the huge demands for advanced engineering materials with specific properties, this study aimed to fabricate novel lightweight materials possessing ameliorated characteristics. The novel hybrid composites were prepared by reinforcing both the bisphenol-A based dicyanate ester and benzoxazine (DCBA/BA-a) resin blends using silane-treated short glass/basalt hybrid fibers through a compression molding technique, and then experimentally characterised. Results from the mechanical and thermal analyses revealed that the mechanical and thermal parameters were highly improved upon increasing the reinforcing phases’ amount. The shielding evaluations disclosed that the integration of hybrid fibers helped the DCBA/BA-a blend to possess excellent nuclear shielding properties.

In this study, a novel composite membrane was developed by casting the mixed aqueous solution of chitosan (CS) and polyvinyl alcohol (PVA) on a glass fiber microporous membrane. The polymeric coating of a composite membrane containing amino groups and hydroxyl groups has a favorable CO2affinity and provides an enhanced CO2transport mechanism, thereby improving the permeance and selectivity of CO2. A series of tests for the composite membranes were taken to characterize the chemical structure, morphology, strength, and gas separation properties. ATR-FTIR spectra showed that the chemical structure and functional group of the polymer coating had no obvious change after the heat treatment under 180 °C, while SEM results showed that the composite membranes had a dense surface. The gas permeance and selectivity of the composite membrane were tested using single gases. The results showed that the addition of chitosan can increase the CO2permeance which could reach 233 GPU. After a wetting treatment, the CO2permeance (454 GPU) and gas selectivity (17.71) were higher than that of dry membranes because moisture promotes the composite membrane transmission. After a heat treatment, the permeance of N2decreased more significantly than that of CO2, which led to an increase in CO2/N2selectivity (10.0).Keywords:carbon dioxide;polyvinyl alcohol;chitosan;glass fiber microporous membrane;gas separation

Oil/ water separation in extreme environments remains a challenging issue, with high requirements for material performance. Polyphenylene sulfide (PPS) has broad application prospects in extreme environments due to its unique performance. In this study, glass fiber cloth (GFC) modified with polydopamine/ phenyltriethoxysilane (PDA/PTES) (hereinafter referred to as MGFC) was used as the support, a superhydrophobic/ superlipophilic PPS nanofiber-like functional layer with low surface energy was prepared via thermally induced phase separation (TIPS) method, (hereinafter referred to as PPS@MGFC composite membrane). Relying on π-π conjugation between PTES and PPS, the composite interface was firmly bonded, effectively enhancing its structural stability . Meanwhile, when the PPS content was 4.2 wt%, the pure-water contact angle reached 156.8°, the oil contact angle reached 0 °. The prepared PPS@MGFC composite membrane showed strong oil-water separation performance in oil-water separation experiments. It could be used to separate various immiscible oil-water mixtures, the water content was less than 150 ppm and flux was higher than 6429 L·m −2 ·h −1 (gravity drive). For oil-in-water emulsions, the water content was less than 250 ppm, the flux was higher than 2500 L·m −2 ·h −1 (0.1 bar), and the separation efficiency was higher than 99.9%. In addition, the separation efficiency and flux remained stable in extreme environments and after recycling use. These results indicated that PPS@MGFC composite membrane created in this study has a significant deal of promise for use in the field of oil/water separation.
