“…[16][17][18] They are more and more popular among researchers because their thermal degradation temperature is above 300 C and they do not thermally degrade when used to modify polymer materials, which is more conducive to improving the thermal stability of materials. [19][20][21][22] However, foreign reports on their specific synthesis methods are incomplete, 23 and domestic research is also immature, so the synthesis methods need to be explored in terms of reaction conditions and reaction solvents.…”

In this study, quaternary phosphonium salt (P4) was prepared, vermiculite (VMT) was modified by P4, and P4@VMT/poly (butylene adipate‐co‐terephthalate) (PBAT) composite film was prepared by the solution method. The structure of the synthesized P4 was determined by nuclear magnetic resonance and infrared. The structure and performance of P4 modified vermiculite were explored and analyzed by particle size, XRD, infrared and micro‐morphology. The structure, thermal properties, crystallization properties, rheological properties, cross‐section morphology, tensile properties and antibacterial properties of pure PBAT film and P4@VMT/PBAT composite film were tested and compared. The results show that the crystallization temperature and melting temperature of P4@VMT/PBAT composite film are higher than those of pure PBAT film. With the increase in P4@VMT content, the thermal stability of the composite film becomes worse, and the crystallization enthalpy, melting enthalpy and crystallinity also decrease, while the storage modulus, loss modulus and complex viscosity of P4@VMT/PBAT composite film increase significantly. In addition, compared with pure PBAT film, the tensile strength of P4@VMT/PBAT‐20% composites decreased by 12.0% and the elongation at break decreased by 95.7%.Highlights Successful synthesis of phosphonium quaternary P4 and modification of vermiculite. The properties of P4@VMT/PBAT composite films with different contents were studied.

“…Gas barrier properties of elastomer materials are of significant importance in tire liners, medical packages, mechanical seal products, chemical protective products, etc. − For example, the excellent gas barrier of elastomer is crucial maintaining the tire pressure, which directly impacts the performances of vehicles in terms of stability, energy consumption, handling and riding comfort . However, most diene based pristine rubbers exhibit high permeability to air because of their large fractional free volume, which has been used to determine the gas permeability in polymers chains .…”

Biomass feedstock is an accessible alternative to finite fossil chemical resources for fabricating durable and high-performance polymers. In this study, fully biobased poly(1,5-pentylene succinate-co-itaconate-co-furanoate) (PPeSIFs) copolyesters were synthesized by using transesterification and melt polycondensation methods from dimethyl furandicarboxylate, dimethyl succinate, dimethyl itaconate, and 1,5pentanediol. Dimethyl itaconate was incorporated to provide the cross-linkable reaction sites. Four kinds of monomers were employed to regulate the glass transition temperature and suppress crystallization. Silica/PPeSIF nanocomposites exhibited good mechanical properties, such as an ultimate tensile strength of 17.2 MPa and an elongation at break of 253%. This elastomer displayed outstanding gas barrier properties comparable to those of butyl rubber, with an O 2 permeability 13 times lower than that of natural rubber. Positron annihilation lifetime spectroscopy tests demonstrated that furan moieties significantly reduced the free volume of PPeSIFs. This work provides a promising route for preparing a biobased elastomer with intrinsic high gas barrier properties.

“…Despite these advancements, these polymers face challenges in terms of high costs, environmental concerns, and performance limitations under specific conditions [16][17][18]. For instance, Ali Behnood et al [19] found that polymer-modified asphalt is 1.5 times costlier than traditional asphalt, leading to a 20% increase in the cost of the modified mixtures.…”

This study comprehensively examines the influence of phenol-formaldehyde resin (PF) on the performance of base asphalt and its mixtures for road applications, emphasizing its innovative use in enhancing pavement quality. Optimal PF content was determined through the evaluation of standard indicators and rotational viscosity. In-depth analyses of PF-modified asphalt’s high- and low-temperature rheological properties and viscoelastic behavior were conducted using dynamic shear rheometers and bending beam rheometers. Aging resistance was assessed through short-term aging and performance grade (PG) grading. Moreover, Marshall and water stability tests were performed on PF-modified asphalt mixtures. Findings indicate that the uniform dispersion of PF particles effectively inhibits asphalt flow at high temperatures, impedes oxygen penetration, and delays the transition from elasticity to viscosity. These unique properties enhance the high-temperature stability, rutting resistance, and aging resistance of PF-modified asphalt. However, under extremely low temperatures, PF’s brittleness may impact asphalt flexibility. Nonetheless, the structural advantages of PF-modified asphalt, such as improved mixture density and stability, contribute to enhanced high-temperature performance, water stability, adhesion, and freeze–thaw cycle stability. This research demonstrates the feasibility and effectiveness of using PF to enhance the overall performance of base asphalt and asphalt mixtures for road construction.
