Summary: The intrinsic characteristics of the matrix can potentially influence the properties of unidirectional flax/thermoplastic composites manufactured by thermocompression. This study aims to determine the impact of recycled matrix on the performance of flax/MAPP/PP composite. Three PP matrices, including one virgin and two recycled ones, were used in the manufacturing process, and a multi-scale analysis identified the characteristics of the matrices that influence the quality of the composite. Chain length of the polymer was found to affect the interface quality, while high viscosity decreased fiber bundle dispersion but could be corrected by modifying process pressure. The presence of a small amount of PE in recycled PP had no significant effect on the mechanical properties of the composites.

Summary: This paper investigates the effect of carboxylic-acid-modified polypropylene (PP) on the mechanical properties of carbon fiber (CF)/polypropylene (PP) composites, and proposes a new interface design to improve the mechanical properties. The addition of carboxylic-acid-modified PP and poly-2-vinyl-2-oxazoline (Pvozo) coating on CF resulted in better interfacial adhesion and improved tensile properties. Increased entanglement with matrix PP molecules and different bonding modes at the CF/PP interface were suggested to contribute to the mechanical properties of the composite.

Summary: This study investigated the development of composite polypropylene drawn fibers and found that the addition of fillers and other additives can improve the thermal and mechanical properties of the fibers. It was found that it was not feasible to maximize both the tensile strength and thermal stability for composites with talc as filler, but the mechanical strength of the fibers could be improved if low drawing ratios were used. On the other hand, it was feasible to optimize and maximize both the tensile strength and thermal stability for composites with single-wall carbon nanotubes as filler.

Summary: The study focuses on recycling carbon fiber composites generated from aircraft component manufacturing and using them to fabricate vinyl ester composites. The results show an increase in tensile strength with the addition of reinforcement, but a decrease with further reinforcement. The compressive and flexural strength of the composites also increased, but there were weak fiber-matrix bonds as observed in the SEM images.

Summary: In this study, lightweight hybrid composites for relevant industrial applications were prepared using surface functionalized hierarchical carbon fibers (f-CF) and silane treated hollow glass microspheres (HGM). The addition of f-CF and HGM significantly improved the mechanical properties and interfacial adhesion of the composites, and uniform dispersion and distribution of the fillers were observed. Furthermore, the addition of HGM led to a desirable reduction in density and melt viscosity, as well as an improvement in composite stiffness.

Summary: The study reveals that adding both CNTs and PP microfibers to cementitious composites can enhance the compressive and flexural strength of mortar at high temperatures, reduce residual fracture energy, and delay crack formation and propagation. However, the improvement is less significant when exposed to temperatures exceeding the melting point of the fibers.

Summary: Conductive plastics, created by adding conductive fillers to polymer matrices, are more effective when used in binary polymer blends with a co-continuous morphology. Embedding aluminium nano platelets, a relatively low-cost conductive filler, in a 60/40 PBT/PET polymer blend resulted in a reduction of resistivity to the level of an electrostatic charge dissipation material. The dimensional stability of the conductive articles remained above the T-g of PET due to the crystallization of the 60/40 PBT/PET blend during injection molding.

Summary: This study investigates the aging of polypropylene composites reinforced with date palm nanofiber in order to predict their long-term performance. The results show that the thermal and mechanical properties of the composites slightly decrease after accelerated weathering, but they still exhibit excellent stability. This research provides insights into the aging behavior of these composites, which can be useful for applications in dry conditions and nonstructural parts with specified minimum tensile strength.

Summary: In this study, the effects of using a 1-butyl-3-methylimidazolium chloride (BMIM+Cl-) ionic liquid on the conductivity and morphological properties of the hole-transport layer (HTL) made of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films were investigated. The conductivity of the acidic PEDOT:PSS film was decreased, while the conductivity of the pH-neutral PEDOT:PSS film was increased. The surface morphology of the pH-neutral PEDOT:PSS film slightly changed, while the surface morphology of the acidic PEDOT:PSS film remained relatively unchanged. Vacuum-free planar hybrid solar cells using the pH-neutral PEDOT:PSS film showed higher power conversion efficiency compared to those using the acidic PEDOT:PSS film.

Summary: In previous works, the addition of micron-sized, irregular-shaped aluminum powder or aluminum nano platelets improved the mechanical properties and electrical conductivity of polyesters. However, when using nano-spherical particles of aluminum in a PBT/PET polyester blend, the tensile strength and flexural strength decreased gradually with increasing filler loading. The spherical shape and nano size of the Al particle caused it to be less effective than the micron-sized, irregular-shaped Al powder or flakes.

Summary: This study investigates the effects of incorporating stearic acid in candelilla wax and groundnut oil oleogel. The results show that stearic acid modifies the crystal structure of the oleogel and increases ordering within the crystallite network. Interestingly, the firmness of the oleogel remains unaffected, but the spreadability decreases with the addition of stearic acid. The addition of stearic acid also affects the color and crystallization rate of the oleogel.

Summary: This research investigated the effects of stearic acid, sunflower lecithin, and sorbitan monooleate on SYW/RBO-based oleogels. The samples were analyzed using various techniques, including colorimetry, microscopy, FTIR, mechanical testing, crystallization kinetics, X-ray diffraction, and drug release investigation. The results showed that emulsifiers did not affect the appearance or oil binding capacity of the oleogels. Emulsifiers smoothed the surface and influenced the crystallization kinetics of the oleogels. The drug release study indicated that emulsifiers had a significant impact on the release of curcumin from the oleogels.
