However, differences among organosilanes during energy dissipation remain insufficiently understood at the molecular level. This study combines experimental work and molecular dynamics (MD) simulations to investigate the effects of vinyltrimethoxysilane (VTMS), methyltrimethoxysilane (MTMS), and tetraethyl orthosilicate (TEOS) on the viscoelastic properties and molecular interactions of MREs. The addition of TEOS as a crosslinker increased the loss modulus (G″) of MREs and produced the highest increment in maximum G″, reaching 400 kPa under a 0.6 T magnetic flux density. The damping properties of VTMS-, MTMS- and TEOS-cured MREs increased at high strain, exceeding the commercial -cured MRE. The observed enhancement in damping for MREs could mainly be attributed to enhanced van der Waals interaction, resulting in a more crosslinked polymer network and greater frictional energy dissipation, as observed in the MD simulation. The thermal stability and microscopic analyses results confirm that the TEOS-cured MRE forms a thermally stable and homogenous structure. This study provides guidelines for selecting suitable organosilane crosslinkers to enhance the damping properties of MREs and is valuable for developing adaptive rubber materials in vibration isolation, and smart damping applications.</p>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"32 2","pages":"375-389"},"PeriodicalIF":3.6,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147569071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PUG was synthesized using polycaprolactone (PCL) diol and chain extenders, including castor oil, 1,4-butanediol, and varying glycidol content as a functional group to enhance compatibility with PLA. The blends of different compositions, thermo-mechanical, rheological, morphological, and biodegradation properties were studied. The FTIR results confirmed the reactive blending, while the rheological studies showed the enhanced structural integrity and elasticity at higher PUG loading. PUG3 blends exhibit superior mechanical properties, especially in the 30% blend ratio, compared to the other formulations (PUG1 and PUG2, which have lower glycidol content), due to the higher glycidol content, which facilitates enhanced reactive blending and interfacial adhesion with PLA. Thermal analysis reveals a reduction in crystallinity and an improvement in thermal stability. However, the biodegradation study reveals that the pristine PLA shows a higher degradation rate compared to the blends, possibly due to the elastomeric PUG reducing the hydrolysis of the ester bond. Therefore, this research demonstrates a novel strategy that integrates bio-based and glycidol-functionalized PUG to achieve superior toughness, interfacial compatibility, and thermal resilience in PLA blends, as well as enhanced biodegradation properties, making it a promising candidate for sustainable packaging applications.</p>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"32 2","pages":"336-349"},"PeriodicalIF":3.6,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novelty of this work lies in utilizing silane-treated SCG as a natural filler within PBS/TPS blends, systematically examining its effect on modulus, strength, flowability, and soil biodegradability.

Furthermore, SCG incorporation significantly accelerated biodegradation, with up to ~38% weight loss after 60 days. However, the results also revealed drawbacks: tensile strength and flexural strength decreased with increasing SCG fractions, primarily due to particle agglomeration and limited interfacial adhesion, as confirmed by FE-SEM analysis. Thermal analysis indicated slight reductions in melting enthalpy and crystallinity without significant changes in glass transition temperature. Overall, PBS/TPS/SCG composites demonstrate potential as biodegradable packaging materials, offering both stiffness enhancement and improved degradability.

Chain-extension techniques overcome these issues by raising molecular weight, introducing branching or cross-linking, and adjusting viscoelasticity. This review surveys advances from 2015 to 2024 in PLA chain extension, covering reaction mechanisms, characterization methods, extender types, and effects on performance and sustainability. Chain-extension mechanisms include esterification (epoxide-based), polycondensation (isocyanate- and anhydride-based), and free-radical coupling (peroxide-based). Processing parameters—temperature, extender concentration, and reaction time—influence molecular architecture. Structural analyses, thermal analyses, and mechanical tests quantify increases in molecular weight, crystallinity changes, and property improvements. Chain extension also alters degradation. Higher molecular weight and modified crystallinity slow hydrolytic and enzymatic breakdown, though additives such as diatom frustules or plant fibers can accelerate biodegradation when desired. Thermal and photo-oxidative stability generally improve, while catalyst systems and processing history affect degradation kinetics. Mechanical loading in tissue engineering illustrates the importance of mechanoresponsive degradation. Socio-economic and sustainability aspects highlight the need to balance cost, scalability, and environmental impact. High-performance extenders often raise costs and may hinder end-of-life degradability, whereas bio-based and recyclable extenders remain in development.
