Summary: Due to the demand for reliable and economical fuel cells, researchers have focused on improving the durability of hydrocarbon-based proton exchange membranes (PEMs) without compromising performance. Cross-linking and blending techniques show promising potential in creating a 3D network within the membrane structure, resulting in improved long-term stability and durability. These membranes have demonstrated over 4000 hours of durability in hydrogen fuel cells and significantly lower methanol crossover compared to conventional fluorinated membranes, indicating their potential for commercialization.

Summary: SPEEK is recognized as a promising alternative PEM in fuel cell applications due to its advantageous properties, but its proton conductivity is influenced by the degree of sulfonation. While high DS of SPEEK can produce high proton conductivity, excessive production of DS may have side effects on membrane stability. Therefore, finding the optimal DS of SPEEK is crucial for fabricating PEM alternatives.

Summary: This study investigated blend membranes based on sulfonated poly (styrene-isobutylene-styrene) (SIBS) with isopentylamine (IPA) for potential direct methanol fuel cell (DMFC) applications, analyzing the impact of sulfonation level and IPA incorporation percentage on membrane properties. Results showed that IPA incorporation enhanced proton conductivity while slightly increasing methanol permeability. Despite this, the selectivity of the membranes was comparable to Nafion at an optimal IPA incorporation of 3 wt%.

Summary: Poly(fluorenyl terphenyl piperidinium) (PFTP) with an aromatic backbone was synthesized to produce proton exchange membranes (PEMs) with robust mechanical properties. The introduction of propanesulfonic acid side chains enhanced the phosphoric acid (PA) adsorption capacity and proton conductivity of the resulting sulfonated PFTP (SPFTP-x) membranes. These membranes exhibited good thermal, oxidization, and dimensional stabilities, and the SPFTP-x membranes showed higher PA adsorption capacity and higher proton conductivity than the PFTP membrane. A single cell assembled with SPFTP-50 exhibited a maximum power density of 280 mW cm-2 at 100 degrees C, indicating the promising application of SPFTP-x as a membrane material for high-temperature proton membrane fuel cells.

Summary: Mechanically-robust nanocomposite membranes for oil and water separation were developed through crosslinking chemistry and electro-spinning technique. The dispersed phase materials with high Young's modulus, such as graphene and multiwalled carbon nanotubes, were selected to enhance the stiffness of the membranes. Chemical modification and induced roughness of the dispersed phase materials were critical for achieving superhydrophobicity. Surface analytic tools were used to characterize the membranes, and AFM-based nanoindentation and TGA/DSC techniques were employed for stiffness measurement and confirmation of composition and formation, respectively. These membranes showed excellent oil/water separation and have potential application in water purification and remediation.

Summary: In this study, a mild and eco-friendly synergistic treatment strategy was utilized to enhance the interfacial compatibility of bamboo fibers with poly(lactic acid). The treated composites exhibited homogeneous dispersion and excellent interfacial compatibility, as confirmed through characterization of chemical structure, surface morphology, thermal properties, and water resistance properties. The proposed synergistic treatment involving dilute alkali pre-treatment, polydopamine coating, and silane coupling agent modification resulted in a multi-layered coating of bamboo fibers, leading to the superior mechanical properties of the composites. The tensile strength, elongation at break, and tensile modulus of the treated composites were significantly improved compared to the untreated composites, indicating the potential applicability of this synergistic treatment strategy in various bio-composite applications.

Summary: Hybrid graphene oxide-polyethyleneimine-coated carbon fibers (ACF/GO-PEI) were prepared through electrophoretic deposition (EPD) to enhance the interfacial performances between carbon fibers and epoxy matrix. The combination of rigid GO sheets and flexible PEI polymer improved the mechanical performances by providing mechanical interlocking and bridging effects. The uniform distribution of GO-PEI sheets on carbon fiber surface increased the surface roughness and energy, leading to a significant enhancement of the interfacial shear strength (IFSS) of the ACF/GO-PEI reinforced epoxy composite.

Summary: In this study, a single-layer functionalized reduced graphene oxide (FRGO) platelet hybrid functionalized silica (FSiO2) binary hybrid filler (FRGO-h-FSiO2) was successfully prepared and incorporated into natural rubber (NR) using electrostatic self assembly and wet mixing process. The introduction of FSiO2 not only significantly improved the dispersibility of FRGO platelets in the NR matrix, but also acted as nano-synapses to fix more rubber molecular chains and improve the compatibility between FRGO-h-FSiO2 filler and matrix. Compared with pure NR, the FRGO-h-FSiO2/NR composites exhibited increased tensile strength, reduced volume resistivity, and higher thermal conductivity.
