In this work, fluoride-functionalized glass fiber (F-GF) was prepared, in which glass fiber (GF) was modified with γ-methacryloxy propyltrimethoxy silane (γ-MPS), and then reacted with 2,2,2-trifluoroethyl methacrylate (TFEMA). Subsequently, PTFE/glass fiber microwave composites were prepared by incorporating 5 wt% of the GF, γ-MPS modified GF (M-GF) or F-GF into PTFE. The effect of F-GF on the mechanical and dielectric properties, as well as moisture absorption and coefficient of thermal expansion of the composites were investigated. The results show that fluorine is successfully grafted onto the surface of GF through –CF3 group, and F-GF forms a dense and compact interfacial structure with PTFE. The mechanical properties of PTFE/F-GF, including tensile strength (38.53 MPa) and elongation (226.82%), are obviously higher than those of PTFE/M-GF (34.73 MPa and 179.50%, respectively) and PTFE/GF (34.82 MPa and 174.33%, respectively). In addition, the PTFE/F-GF composite shows improved density (2.174 g cm−3), dielectric constant (2.18), and decreased dielectric loss (0.0009), moisture absorption (0.008%) and temperature coefficient of dielectric constant (−18.6 ppm per °C). The conclusions demonstrate that the method of surface fluorination of glass fibers offers promising application in PTFE based microwave materials.

The use of glass fibers (GFs), molybdenum disulfide (MoS 2 ), and talc was evaluated to reinforce polytetrafluoroethylene (PTFE) for potential applications in automobile shock absorber pistons. The orthogonal experiment results show that the optimal GF/MoS 2 /talc/PTFE weight ratio was 2:3:3:92 for the PTFE composite; this ratio resulted in better mechanical properties, hardness, low linear expansion, and wear rate. Chemical coupling and high-temperature activation treatment on the surface of GF greatly enhanced the interfacial adhesion between the PTFE matrix and GF, as revealed by atomic force microscopy analysis. This resulted in reductions in the wear rate and linear expansion coefficient by two orders of magnitude compared with that of PTFE. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Carbon materials have attracted increasing attention and have been used as extraordinary electrodes for high-performance supercapacitors (SCs) to satisfy the demand for energy reservation and transformation due to their fast current response and excellent cycling stability. Herein, we provided a novel approach to prepare 2D flexible electrode which was composed of glass fabric coated with tannin derived carbon (GFTC). In this strategy, each glass fiber with outstanding mechanical flexibility in the center was served as support and the outer ultrathin carbon coating derived from tannin play the role of active material, forming the coaxial structure. Two pieces of as-prepared GFTC with the highest specific capacitance of 315.7 mF cm − 2 were assembled into a 2D all-solid-state symmetric supercapacitor (ASSC) which possessed the largest energy density of 6.03 μWh cm − 2 and the superior cycling stability with 93% capacitance retention after 10,000 cycles at 2 mA cm − 2 . Furthermore, the 2D ASSC realized practical application by coordinating with solar panels as a power supply. More importantly, this strategy can also be extended to prepare 1D flexible electrode by using glass yarn as support instead of glass fabric. The assembled 1D ASSC could be used as a wristband to be applied in wearable electronics. Thus, this work shows a new way to fabricate 1D/2D flexible electrodes and SCs with high performance for next-generation energy storage devices.

In this work, the antistatic effect of antistatic agent (AA) on semi-aromatic poly (decamethylene terephthalamide) (PA10T) with 30 wt.% glass fiber (GF) was investigated. The PA10T/AGF antistatic composites with excellent thermal characteristics, balanced toughness, and notched impact strength were prepared through one-step melt blending, and added the AA and GF to the PA10T matrix. Meanwhile, the structure, morphology, thermal properties, and mechanical properties were examined in detail by FT-IR, SEM, TGA, DSC, and tensile and impulse testing. The results showed that the antistatic GF dispersed well in the PA10T matrix and interacted well with the PA10T matrix. The antistatic properties increased with the increase of AA content, and AA/GF-5 composites had the best antistatic effect when AA content was 25 wt.%. However, with the increase of AA content, the melt temperature of PA10T/AGF composites decreased, while the machining performance and thermal stability of PA10T/AGF composites increased. The composites' tensile strength and breaking elongation followed a rising and falling pattern with increasing AA concentration. Notwithstanding, the notched impact strength of PA10T/AGF composites decreased and then increased. Therefore, this work provides us with a deep understanding of the antistatic effect of AA on polymers.

Recently, poly(ethylene oxide) (PEO)-based solid polymer electrolytes have been attracting great attention, and efforts are currently underway to develop PEO-based composite electrolytes for next generation high performance all-solid-state lithium metal batteries. In this article, a novel sandwich structured solid-state PEO composite electrolyte is developed for high performance all-solid-state lithium metal batteries. The PEO-based composite electrolyte is fabricated by hot-pressing PEO, LiTFSI and Ti 3 C 2 T x MXene nanosheets into glass fiber cloth (GFC). The as-prepared GFC@PEO-MXene electrolyte shows high mechanical properties, good electrochemical stability, and high lithium-ion migration number, which indicates an obvious synergistic effect from the microscale GFC and the nanoscale MXene. Such as, the GFC@PEO-1 wt% MXene electrolyte shows a high tensile strength of 43.43 MPa and an impressive Young's modulus of 496 MPa, which are increased by 1205% and 6048% over those of PEO. Meanwhile, the ionic conductivity of GFC@PEO-1 wt% MXene at 60 °C reaches 5.01 × 10 −2 S m −1 , which is increased by around 200% compared with that of GFC@PEO electrolyte. In addition, the Li/Li symmetric battery based on GFC@PEO-1 wt% MXene electrolyte shows an excellent cycling stability over 800 h (0.3 mA cm −2 , 0.3 mAh cm −2 ), which is obviously longer than that based on PEO and GFC@PEO electrolytes due to the better compatibility of GFC@PEO-1 wt% MXene electrolyte with Li anode. Furthermore, the solid-state Li/LiFePO 4 battery with GFC@PEO-1 wt% MXene as electrolyte demonstrates a high capacity of 110.2–166.1 mAh g −1 in a wide temperature range of 25–60 °C, and an excellent capacity retention rate. The developed sandwich structured GFC@PEO-1 wt% MXene electrolyte with the excellent overall performance is promising for next generation high performance all-solid-state lithium metal batteries.

Laminated glasses have been widely used in buildings, physical protections, and vehicles because of their safety, sound insulation, thermal insulation, and other performance. In recent years, the high sound insulation performance of laminated glass intermediate films in the frequency range of low or high frequencies has attracted more and more attentions. In this work, a glass fiber/polyurethane elastomer composite (PU-MGF) film with high transparency and impact resistance has been successfully synthesized, 5 dB of the transmission loss increased at 1600–6000 Hz, and 3.6 dB increased at 63–1600 Hz compared with the control polyurethane film. This is a significant progress in the laminated glass industry. In addition, the transmittance of the composite reaches over 75%. The excellent impact resistance of the laminated glass, based on PU-MGF film, has been confirmed through falling ball impact test, demonstrating its ability to withstand multiple impacts without spattering. The PU-MGF film prepared in this work exhibits great potential for applications in building windows, transportation, and soundproof devices.

The flame-retardant performance of carbon fiber-reinforced composites is crucial for ensuring structural stability. Traditional additive flame-retardant methods often struggle to balance structural integrity with fire resistance. Herein, Ni(OH)2and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) were used as flame-retardant agents and mixed with glass fibers to construct the flame-retardant functional fiber veil which was used as the skin layer on the composite surface for fire protection. The structure performance and flame retardancy of composites were characterized via Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and a cone calorimeter test. The results confirmed that a flame-retardant glass fiber mat could effectively improve the flame-retardant and smoke-suppressive properties of the composite material. Due to the synergistic flame-retardant mechanism of Ni(OH)2and DOPO, the C-N3-D2 composite with the highest LOI value of 32.3% has shown significant reduction in peak heat release rate (PHRR) and total smoke production (TSP) by 31.3% and 19.5%, respectively. In addition, due to flame-retardant agents only being employed in the skin layer of the composite, the core layer of a carbon fiber-reinforced structure could be protected without structure disruption. This approach maintained consistent interlayer shear strength, highlighting the effectiveness of using a flame-retardant fiber veil as a protective skin layer. This strategy could offer a viable solution for safeguarding high-performance composite materials from fire hazards without compromising their structural integrity.

To address the challenges of high brittleness and poor crystallization capability in polylactic acid (PLA), glass fiber (GF), and polycaprolactone (PCL) were selected as reinforcing and toughening agents, respectively, for property modification. In the resulting composites, an interfacial layer forms between the polymer matrix and GF, significantly influencing the interfacial adhesion quality and the overall mechanical properties of the material. To enhance interfacial compatibility, oleic acid (OA) was introduced as a coating via the hydrophilic Si O Si bonds on the GF surface. Combined with treatment using a silane coupling agent (KH550), this process resulted in dual-surface modification of glass fiber (OKGF). PLA/PCL/GF (or OKGF) composites with mass fractions of 5%, 10%, 15%, and 20% OKGF were fabricated using solution dissolution and melt blending techniques. Scanning electron microscopy analysis revealed excellent interfacial adhesion between OKGF and the polymer matrix. The composite with 15% OKGF content exhibited optimal mechanical properties, achieving maximum tensile strength (65.5 MPa) and modulus (1113.0 MPa), representing a significant enhancement. Moreover, OKGF served as an effective heterogeneous nucleating agent, resulting in a crystallinity of 19.1% at 15% OKGF content—an 88% increase compared with the PLA/PCL blend (10.2%).

In this study, the refractive index of epoxy resin was adjusted according to the mixing ratio of two types of curing agents, namely 4,4′-diaminodiphenylmethane and poly(propylene glycol) bis(2-aminopropyl ether). The optical properties of the cured pure polymers and transparent glass fiber-reinforced plastics (GFRP) 1 (analyzed with an ultraviolet–visible spectrophotometer) were compared. Epoxy (EP)/P9D1-F exhibited excellent optical properties (transmittance of 89.54 % and a haze of 9.30 %). The small refractive index difference between EP/P9D1 and glass fiber reduced the phase delay and fabricated high-transmittance, transparent GFRP. In addition, EP/P9D1-F exhibited superior mechanical properties, with enhanced flexural strength and fracture toughness owing to the improved stress distribution between the fiber and matrix. These findings suggest that a transparent GFRP with high transmittance and glass-like optical properties, as well as excellent mechanical performance, can be fabricated by appropriately mixing and adjusting two or more types of curing agents.

This paper reports a novel glass fiber membrane with an effective antibacterial performance by chemical grafting of quaternary ammonium salt (QAS) which is enhanced by a plasma bombardment technique. Plasma bombardment as a pretreatment of the membrane can increase the QAS anchored on the membrane from 0.8 to 1.3 wt %. The chemical grafting technique can increase the membrane zeta potential from negative values to positive values in aqueous solutions at various pHs. Furthermore, the plasma-enhanced chemical-grafting membrane has more positive zeta potentials (49.0 mV at pH = 7) than the chemical-grafting membrane without the plasma bombardment technique (38.9 mV at pH = 7). In the antibacterial performance evaluation, the Escherichia coli survival rate decreased from 127.0% of the pristine membrane to 4.1 and 11.3% of the plasma-enhanced chemical-grafting membrane and the chemical-grafting membrane, respectively. In addition, the plasma-enhanced chemical-grafting membrane shows durable antibacterial activity against E. coli with copious water rinsing as much as 3 L·cm–2.

Optically transparent and mechanically strong glass fiber (GF)-reinforced polycarbonate (PC) composites were fabricated via reacting with biorenewable isosorbide (ISB) moiety. While direct copolymerization of ISB and bisphenol A (BPA) by melt transesterification with diphenyl carbonate remained difficult due to the large discrepancy of reactivity and low thermal stability of ISB, we demonstrated in this work that ISB and BPA copolycarbonates with high molecular weight, low discoloration, and excellent optical transparency can be fabricated at 250 °C within 2.5 min by reactive blending of commercially available ISB-based PC and BPA-PC. A systematic study of synthesis, thermal degradation, and reactive blending of ISB-containing PCs was performed to distinguish the reactivity between ISB and BPA, elucidate the effect of catalyst on chain scission, and testify the reaction mechanism of the unexpected asymmetrical inner–inner carbonate exchange. We clarified that the hydroxyl group on BPA exhibited a low reactivity and Lewis acid-catalytic transesterification played a key role in preventing from the chain scission during the asymmetrical inner–inner exchange. Another unexpected factor that effectively suppressed the further chain scission was the miscibility of the ISB-based PC with BPA-PC once each chain on average was carbonate exchanged with its counterpart to form a “biblock” PC. © 2019 Wiley Periodicals, Inc.

Lithium-sulfur batteries are attractive for energy storage due to their ultrahigh theoretical energy density and low material cost. But the biggest factor impeding the development of the batteries is its rapid irreversible capacity decay due to the “shuttle effect.” To inhibit it, the glass fiber membrane modified by magnetic mesoporous Fe 3 O 4 mixed with Ketjen black is designed and used as the separator for lithium-sulfur batteries in this work. The assembled battery using the modified separator exhibits an excellent initial capacity of 1274.5 mA h g −1 and a high coulombic efficiency of about 90% at 0.2 C first cycle. The improved performance of batteries can be ascribed to the good conductivity, mesoporosity, and magnetic property of Fe 3 O 4 nanoparticles on the separator, which enables the trapping and activation of the soluble polysulfides in lithium-sulfur batteries. The work indicates that magnetic mesoporous Fe 3 O 4 can open new avenues to improve the performance of lithium-sulfur batteries.
