The addition of bentonite significantly reduced the tensile strength and elongation at break due to the filler's inherent brittleness. Pure ABS exhibited a tensile strength of 42.2 MPa, which decreased by 16.1% with the incorporation of 20% bentonite (ABS1). Impact strength tests showed that the inclusion of bentonite lowered impact resistance, particularly in notched samples. Bentonite also increased the hardness and density, reflecting improved rigidity but reduced flexibility. Surface gloss changed from semigloss to matte, and FT-IR spectroscopy confirmed the successful integration of bentonite. Water absorption tests revealed that DEHPA-modified bentonite composites had higher absorption over time, highlighting the modification's effect on hydrophilicity. While bentonite improves certain properties, the balance between mechanical strength and flexibility needs to be further explored to meet the requirements of specific applications such as automotive components, electronics casings, and construction materials.","PeriodicalId":16888,"journal":{"name":"Journal of Polymer Science","volume":"63 6","pages":"1505-1517"},"PeriodicalIF":3.9,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pol.20240925","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss the selection of appropriate biopolymers based on their mechanical properties, biocompatibility, and biodegradability, as well as the key functions of ECM structures in cell attachment, migration, and differentiation. We analyze the strengths and limitations of each technique, noting that while ES enhances cellular adhesion and proliferation, it struggles with complex geometries and scalability. In contrast, 3D printing provides strong structural support but faces challenges with resolution and biomaterial compatibility. Our review focuses on the innovative integration of these methods, aiming to merge ES's microstructural precision with 3D printing's structural strength. We evaluate various hybrid combination methods, including sequential and coaxial techniques, and discuss potential solutions to challenges related to ECM scaffold quality, production time, and scalability. Furthermore, we highlight recent discoveries and propose future research directions to enhance further mimicking the ECM scaffold of bone.","PeriodicalId":16888,"journal":{"name":"Journal of Polymer Science","volume":"63 6","pages":"1481-1504"},"PeriodicalIF":3.9,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pol.20241010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorporating maximum silica filler into naturally derived elastomers, particularly cis-1,4-polyisoprene (CPI), presents a significant opportunity for the tyre industry to produce environmentally friendly and sustainable tyres with a reduced carbon footprint. However, achieving uniform dispersion of silica filler in CPI is challenging because of the disruption of silanization reactions by non-rubber substances, primarily proteins and phospholipids, present in CPI. This study explores the introduction of various cost-effective carbohydrates (i.e., Arabinose, Sucrose, Sorbitol, and Xylose) into the CPI matrix at different silica filler loadings to mitigate interference during silanization. Among these, the polyol group sugar alcohol, sorbitol, notably enhanced silica dispersion within the CPI matrix. The inclusion of sorbitol not only minimized rolling resistance but also improved processing behavior and significantly enhanced mechanical properties. The use of bio-based sugar alcohols in tyre production holds promise for advancing the development of eco-friendly and sustainable tyres. Molecular dynamics simulations of CPI with these carbohydrates and silica filler demonstrate minimal structural deviation in CPI and maximum network formation, particularly with sorbitol.

Leveraging the expansive and high-quality experimental data sets generated by fractionating polymers using automated chromatography, this machine-learning method effectively reduces data dimensionality by extracting chemical-independent features from SAXS data. This new approach allows for the rapid and accurate prediction of morphologies without repetitive and time-consuming manual analysis, achieving out-of-sample predictive accuracy of around 95% for both novel and existing materials in the training data set. By focusing on a subset of samples with large predictive uncertainty, only a small fraction of the samples needs to be inspected to further improve accuracy.
