The wear of tires rubber is influenced by various factors such as formula composition (such as butadiene rubber content), rubber strength, heat generation performance, etc. It is a complex problem involving mechanics and thermodynamics. Unfortunately, commonly used wear testing equipment in the tire industry, such as DIN abrasion, Akron abrasion, and Lambourn abrasion, cannot accurately characterize the wear performance of tires. The ABS control slippage during vehicle acceleration and braking provides sufficient grip in contact with the road surface, which is the most critical cause of tire wear. The wear performance of rubber at different slippage is a key factor affecting tire life. In this study, three compounds were developed, differing significantly in hardness, modulus, and the filling ratio of silica, to be manufactured as tire tread. The slippage was calculated with the results of the tire pattern model and pressure blanket tests. Subsequent wear performance tests were conducted on a fully automated wear testing machine under different slippage. Compared to the DIN and Cut-chip test results, the correlation with the taxi road test outcomes was enhanced when different slip rates were considered. This study introduces a novel method for assessing wear by calculating the tire slippage. By accounting for variables such as tire pattern and rubber rigidity, the slippage under ABS-controlled conditions was determined. Consequently, the wear performance demonstrated a stronger correlation with tire mileage as evidenced by the taxi road tests.</div></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"142 ","pages":"Article 108684"},"PeriodicalIF":5.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143172168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods used to analyze the nonlinear viscoelasticity of non-Newtonian fluid under large amplitude oscillatory shear (LAOS) cannot be directly applied to the corresponding situation of solid viscoelastic materials due to strict symmetry of LAOS. In this work, a typical UV-cured resin mainly used for 3D printing is chosen to investigate the nonlinear viscoelasticity and its asymmetry under LAOA loading. Based on Fourier transform, the geometric description of stress–strain curve is used to quantitatively characterize the asymmetric nonlinear viscoelasticity. Further, the global asymmetry ratios of nonlinear viscoelasticity under LAOA loading are developed based on the sequence of physical process (SPP) approach throughout the entire oscillatory cycle. We also define an asymmetric ratio of nonlinear viscoelasticity with clear physical meaning from the perspective of energy, which can comprehensively characterize the nonlinear elastic and viscous behavior during the tensile and compressive phases within an oscillatory cycle. Besides, the influences of oscillatory frequency and UV exposure time on asymmetric nonlinear viscoelasticity of UV-cured resin under LAOA loading can be captured as well. These approaches are suitable for evaluating the asymmetric nonlinear viscoelasticity of a large category of viscoelastic solid materials under LAOA loading, which is crucial for analyzing the nonlinear viscoelastic mechanism and for corresponding engineering applications.</div></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"142 ","pages":"Article 108661"},"PeriodicalIF":5.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A <em>β</em>-nucleating agent (TMB-5) was incorporated into the polypropylene/ethylene–propylene rubber (PP/EPR) system to address the challenges of enhancing low-temperature toughness. Under an extreme low-temperature condition of −40 °C, the PP/EPR/TMB-5 blends exhibit a remarkable enhancement in low-temperature toughness compared with PP/EPR blends, showing a 138 % increase to reach 38.3 kJ/m².

The addition of TMB-5 provides numerous nucleation sites that facilitate the <em>β</em>-crystallization of polypropylene, leading to an increased content of <em>β</em>-crystals and a reduction in crystal grain size. Broadband dielectric relaxation spectroscopy shows that the constrained relaxation of EPR near the crystals shifts to higher temperatures with the formation of <em>β</em>-crystals. The lamellar structure of the <em>β</em>-crystals prevents the aggregation of EPR rubber domains during cooling process, resulting in reduced rubber particle spacing. Observations of remarkable shear deformation and extensive stress-whitening areas on the fracture surfaces of PP/EPR/TMB-5 blends upon impact at −40 °C, as opposed to PP/EPR blends, underpin that the lamellar structure of <em>β</em>-crystals within the composite material efficiently transmits stress further away, facilitating the involvement of more EPR particles in energy dissipation.

The adsorption data follows pseudo-second-order kinetic and Langmuir isotherm models. The adsorption was physical and reversible. As a result, drug release was checked. The Fe₃O₄@MIL-101-OH/Chitosan exhibited a controlled release over the period of 84 h at pH 5 and reached 80 % of the DOX release rate after 60 h.
