Summary: The effect of chemical composition on the morphology and microstructure of PEEK/RGO nanocomposite coatings was analyzed. RGO induced three main morphological features and modified the surface roughness through the control of RGO content. Additionally, RGO influenced the melting and crystallization behavior of the polymeric matrix and promoted the transcrystallinity of PEEK.

Summary: The thermoelectric properties of melt-processed poly(ether ether ketone) (PEEK) composites with 10 wt.% of carbon nanofibers (CNFs) were investigated at temperatures ranging from 30 degrees C to 100 degrees C. The composites exhibited a negative temperature effect in their electrical conductivity and a lower Seebeck coefficient compared to the as-received CNFs. The negative Seebeck coefficient was attributed to impurities in the CNFs, while the lower Seebeck coefficient was caused by a slight electron withdrawing effect from the PEEK matrix.

Summary: The study demonstrates that adding 20% basalt fibers to PAEK composite can increase crystallization temperature and melting enthalpy, with higher crystallinity. This composite shows good heat resistance and thermal barrier properties, along with better dynamic mechanical performance and the lowest damping coefficient; excessive basalt fiber addition may lead to fiber agglomeration in the matrix.

Summary: This study used PAEK resin with a low melting temperature to prepare laminate for CCF-PAEK composites, followed by injection of high melting temperature PEEK or SCF-PEEK for overmolding. The interface properties of the composites were affected by the interface temperature, which was adjusted by mold temperature. Higher interface temperatures resulted in better interfacial bonding between PAEK and PEEK. The melting temperature did not significantly affect the shear strength of SCF-PEEK/CCF-PAEK short beams.

Summary: This study investigated the mechanical properties of partially crystalline Poly-Ether-Ether-Ketone between the glass transition and the cold crystallization, observing three stiffening behaviors influenced by temperature-induced crystallization. The results show that the stiffening behaviors are connected to the onset of crystallization, providing a new tool to approach and distinguish extrinsic and intrinsic properties during characterization. This conclusion could promote future implementation for constitutive modeling and corresponding simulation replicating the influence of temperature-induced crystallization.

Summary: This study synthesized fluorene-based poly(aryl ether ketone) (aPAEK) to improve the interlayer adhesion of poly (ether ether ketone) (PEEK) parts, with the tensile strength of 30 mol% fluorene-based aPAEK increased to 75 MPa and the interlayer strength of 20 wt% blends increased by 315% compared to PEEK. The selection of an appropriate molecular weight for aPAEK is crucial in maintaining the elevated tensile strength while promoting interlayer diffusion during the printing process.

Summary: This work focuses on evaluating the proton conductivity and dielectric properties of graphene oxide (GO) doped sulfonated poly(ether ether ketone) (SPEEK) electrolytes. The results show that the oxy-groups in the GO structure enhance proton conduction via the Grotthus mechanism, leading to a proton conductivity value four times higher than that of the pure polymer matrix. In addition, GO increases the dielectric constant through its large surface area and polar functional groups.

Summary: Embedding carbon fibers in CNT-PEEK powders can significantly improve the interfacial shear strength between the fiber and the matrix. The interfacial shear strength is negatively correlated with the fiber length, indicating brittle fracture at the fiber-matrix interface. The pulled out carbon fibers are still coated with the matrix, indicating strong adhesion at the interface.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: A variety of hierarchical nanoporous silica aerogels were synthesized from well-dispersed silica sols, exhibiting diversified particle distributions and excellent thermal properties. The silica aerogels showed low thermal conductivity and high-temperature resilience. Surface modification and dilution of silica sols further improved the thermal resistance of the aerogels. The resilient skeleton structure developed from tiny particles effectively restricted heat dissipation and maintained the porous network at high temperatures.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
